mats/bldnt.bat workarea c/scheme.rc s/7.ss s/cmacros.ss
release_notes/release_notes.stex csug/csug.stex
- added missing include
killme.c
- added new mat verifying that primitives raise exceptions for invalid
arguments based on primdata.ss signatures. fixed some of those
signatures, which weren't otherwise used except for arity checking.
fixed some issues turned up by the test with who reports errors
and how.
primdata.ss, 5_1.ss, 7.ss, compile.ss, cpnanopass.ss, fasl.ss,
interpret.ss, io.ss, record.ss, syntax.ss,
primvars.ms, 5_1.ms, 7.ms, 8.ms, record.ms, mats/Mf-base,
root-experr*, patch*
- string comparisons (string=?, string-ci<?, etc.) now get out fast
when handed eq arguments.
5_4.ss
- changed representation of most-negative iptr, I32, and I64 to make
Visual C compiler happy. updated windows make files, which had
fallen out of date. added missing hsrc= files sort.h and thread.h
so they show up in the Windows workarea c directory.
cmacros.ss,
fasl.c, number.c, c/Mf-base, c/Makefile.{t,}{i3,a6}nt
- The scheme.h definition of Sfixnum(x) now uses multiply rather than
left shift to avoid counting on the behavior of << on negative numbers,
which is undefined in C.
mkheader.ss
- Fixed a couple of casts, one harmless and the other causing
Sinteger64_value to return 0 for the most-negative I64 on 32-bit
builds.
number.c
- The configure-generated Makefile distclean target no longer removes
zlib and nanopass, since they are logically part of the git clone.
It does run make distclean in zlib.
makefiles/Makefile.in
- converted s_test_schlib shifts of -1 to equivalent shifts of 1 to
avoid undefined left-shift behavior on negative numbers.
prim5.c
- added if(---) {} wrapper around call to WRITE in display macro to
silence unused return-value warnings.
prim5.c
- liberalized get-mode check for ../mats. it's not our business whether
people make their directories group and/or other writable.
6.ms
- make test now prints the actual relative path to summary in the
"check summary" message, whether invoked from the top-level directory
or from the workarea.
Makefile.in, Makefile-workarea.in
- configure now just uses cat to copy Makefile-workarea.in to $w/workarea,
since the file is presently the same regardless of the configuration.
configure
- fixed time-utc->date test in mat time&date-printing to work regardless of
what locale (and time zone) the host machine has set.
date.ms
- fixed date->time-utc to honor the zone-offset field when converting a date
object to a time-utc object.
stats.c,
date.ms
- fixed incorrect handling of library-extension when searching wpo files
compile.ss,
7.ms
- modified floatify_normalize to properly round denormalized results.
obviated scale_float in the process.
number.c,
ieee.ms
- fixed 0eNNNN for large NNNN to produce 0.0 rather than infinity
strnum.ss,
5_3.ms
- the reader now raises an exception with condition type implementation
restriction (among the other usual lexical condition types), and
string->number now raises #f, for #e<m>@<a>, where <m> and <a> are
nonzero integers, since Chez Scheme can't represent polar numbers other
than 0@<n> and <n>@0 exactly. <m>@<a> still produces an inexact result,
i.e., we're still extending the set of inexact numeric constants beyond
what R6RS dictates. doing this required a rework of $str->num, which
turned into a fairly extensive rewrite that fixed up a few other minor
issues (like r6rs:string->number improperly allowing 1/2e10) and
eliminated the need for consumers to call $str->num twice in cases
where it can actually produce a number. added some related new tests,
including several found missing by profiling. added a couple of
checks to number->string the absence of which was causing argument
errors to be reported by other routines.
strnum.ss, exceptions.ss, read.ss
5_3.ms, 6.ms, root-experr*, patch*
- added pdhtml flag, which if set to t causes profile-dump-html to be
called at the end of a mat run.
mats/Mf-base
- compile-whole-program and compile-whole-library now copy the hash-bang
line from the wpo file (if it has one) to the object file.
compile.ss,
7.ms
- stex is now a submodule. csug/Makefile and release_notes/Makefile
set and use the required Scheme and STEXLIB variables accordingly.
they default the machine type to a6le, but this can be overridden
and is by the generated top-level Makefile. the generated top-level
Makefile now has a new docs target that runs make in both csug and
release_notes, and an updated distclean target that cleans the same.
the annoying csug Makefile .fig.pdf rule redefinition is now gone.
copyright.stex and csug.stex now list May 2016 as the revision month
and date; this will have to be updated for future releases.
configure, makefiles/Makefile.in,
csug/Makefile, copyright.stex, csug.stex,
release_notes/Makefile
- added custom install options. workarea creates an empty config.h,
and configure creates a config.h that sets the default scheme heap
path and scheme-script name based on the actual configuration.
configure, newrelease, workarea, checkin,
c/Mf-base, scheme.c, main.c,
Mf-install.in
- renamed the installed example directory from lib to examples.
Mf-install.in,
scheme.1.in
- added force option to gzip during man page install to prevent gzip from
asking for permission to overwrite existing man page files.
Mf-install.in
- removed ~/lib/csv%v/%m from the default scheme heap path on unix-like
systems. documented inclusion of %x\..\..\boot\%m in the Windows
default scheme heap path.
main.c,
use.stex
- added new configuration options: --installbin, --installlib,
--installschemename, --installpetitename, and --installscriptname.
configure
- updated the example library link to the nanopass framework.
CONTRIBUTING.md
- now cleaning up petite.1 and scheme.1 left behind by make install
Makefile-workarea.in, checkin
- now removing workarea after cleaning csug and release_notes so
Mf-stex (included from csug/Makefile and release_notes/Makefile)
doesn't complain trying to determine the machine type.
Makefile.in
- added installsh support for --ifdiff so the csug make file can use it
for the install target.
installsh,
csug/Makefile
- added instructions for building (cross-compiling) a boot file for
a supported machine type for which a boot file is not built by default.
BUILDING
- corrected CHEZSCHEMELIBS and CHEZSCHEMEEXTS index entries to be
CHEZSCHEMELIBDIRS and CHEZSCHEMELIBEXTS.
use.stex
- updated to curl stex version 1.2.1
configure
- updated the fix to S_mktime to work on windows. the struct tm
structure on windows does not have the tm_gmtoff field used in the
mac and linux version of the code.
stats.c
- updated the Windows makefiles for building and testing to remove links for
files that no longer exist, which was getting in the way of creating links
for files that do exist. Also updated the build batch file for Windows to
compile the nanopass framework separately before building the rest of the
scheme compiler and libraries.
s/Mf-{a6,i3,ta6,ti3}nt, s/bldnt.bat,
mats/Mf-{a6,i3,ta6,ti3}nt
- updated the read me to include a link to the Chez Scheme project page.
README.md
- fixed embarrassing typo in read me.
README.md
- profiler's html output refresh: mark the files as HTML5 rather
than HTML4; use target attributes rather than onclick events to
open links in specific windows; add a missing table row element;
replace the deprecated name attribute with an id attribute (and
replace the anchors with spans); and replace the deprecated valign
attribute with a style attribute.
pdhtml.ss
9.4.1 changes:
- updated version to 9.4.1
bintar BUILDING NOTICE makefiles/Mf-install.in scheme.1.in
c/Makefile.i3nt c/Makefile.a6nt c/Makefile.ti3nt c/Makefile.ta6nt
mats/bldnt.bat workarea c/scheme.rc s/7.ss s/cmacros.ss
release_notes/release_notes.stex csug/csug.stex
- updated newrelease to produce the correct log-entry format and
fixed the existing 9.4.1 log entry
newrelease, LOG
- replaced a couple of tabs
number.c
- updated the descriptions of statistics and related functions to
reflect the Version 9.3.1 change from sstats structures to sstats
records, with sstats times represented as time objects and sstats
bytes and counts represented as exact integers; also updated the
sstats-difference description to reflect that it no longer coerces
negative differences to zero. added a corresponding release note.
system.stex,
release_notes.stex
- added a cast to eliminate a warning
c/number.c
- fixed bug in Windows version of directory-separator-predicate when
path-* procedures are passed a path that is not a string.
s/6.ss
- fixed bug in cp0 on Windows with $foreign-wchar?.
s/cp0.ss
- Cygwin is now used on Windows, updated mats, eliminated unused killme
BUILDING c/*nt c/Mf-base c/scheme.exe.manifest configure
examples/Makefile mats/6.ms mats/Mf-* mats/foreign.ms mats/ftype.ms
mats/patch-* mats/windows.ms s/Mf-*nt s/Mf-base workarea
release_notes.stex
- fixed spelling of non-existent
s/syntax.ss
- now forcing zlib configuration before compiling files that depend on
the zlib header files, since zlib's configure script can modify the
header files. removed ZlibInclude variable, which no longer serves
a purpose.
c/Mf-*, c/Makefile.*nt
- removed unnecessary datestamp.c target
c/Mf.*nt
- fixed unnecessary blocking in expeditor on Windows.
c/expeditor.c
- eliminated a couple of thread-safety issues and limitations on the
sizes of pathnames produced by expansion of tilde (home-directory)
prefixes by replacing S_pathname, S_pathname_impl, and S_homedir
with S_malloc_pathname, which always mallocs space for the result.
one thread-safety issue involved the use of static strings for expanded
pathnames and affected various file-system operations. the other
affected the file open routines and involved use of the incoming
pathname while deactivated. the incoming pathname is sometimes if not
always a pointer into a Scheme bytevector, which can be overwritten if a
collection occurs while the thread is deactivated. the size limitation
corresponded to the use of the static strings, which were limited to
PATH_MAX bytes. (PATH_MAX typically isn't actually the maximum path
length in contemporary operating systems.) eliminated similar issues
for wide pathnames under Windows by adding S_malloc_wide_pathname.
consumers of the old routines have been modified to use the new
routines and to free the result strings. the various file operations
now consistently treat a pathname with an unresolvable home directory
as a pathname that happens to start with a tilde. eliminated unused
foreign-symbol binding of "(cs)pathname" to S_pathname.
io.c, externs.h, new_io.c, prim5.c, scheme.c, prim.c
- various places where a call to close or gzclose was retried when
the close operation was interrupted no longer do so, since this can
cause problems when another thread has reallocated the same file
descriptor.
new_io.c
- now using vcvarsall type x86_amd64 rather than amd64 when the
former appears to supported and the latter does not, as is the
case with VS Express 2015.
c/Mf-a6nt, c/Mf-ta6nt
- commented out one of the thread mats that consistently causes
indefinite delays under Windows and OpenBSD due to starvation.
thread.ms
- increased wait time for a couple of subprocess responses
6.ms
- added call to collector to close files opened during iconv mats
specifically for when mats are run under Windows with no iconv dll.
io.ms
- fixed typo: VC/bin/vcvars64.bat => VC/bin/amd64/vcvars64.bat
c/Mf-a6nt, c/Mf-ta6nt
- scheme_mutex_t now uses volatile keyword for owner and count fields
because these fields can be accessed from multiple threads
concurrently. Updated $yield and $thread-check in mats/thread.ms to
be more tolerant of timing variability.
c/types.h, mats/thread.ms, release_notes.stex
- fixed three instances of unchecked mallocs reported by laqrix in
github issue #77.
io.c, schlib.c, thread.c
- continue the profiler's html output refresh: refine the styling
(and palette) and update CSUG to match. update the CSUG screenshots
to reflect the refined look.
s/pdhtml.ss
csug/system.stex
csug/canned/profilehtml-orig.png
csug/canned/profilehtml.png
csug/canned/fatfibhtml-orig.png
csug/canned/fatfibhtml.png
- add unicode support to the expression editor. entry and display now work
except that combining characters are not treated correctly for
line-wrapping. this addresses github issue #32 and part of issue #81.
c/expeditor.c, s/expeditor.ss
- moved s_ee_write_char function within the WIN32 check to allow the unicode
change to compile on windows. unicode is not yet supported in the windows
version of the repl.
c/expeditor.c
- reworked the S_create_thread_object to print an error and exit when
allocating the thread context fails from Sactivate_thread. before
this change, the error was raised on the main thread, which resulted
in strange behavior at best. also added who argument to
S_create_thread_object to allow it to report either Sactivate_thread
or fork-thread led to the error.
externs.h, schsig.c, scheme.c, thread.c
- fixed a bug in cpvalid resulting in it leaving behind a cpvalid-defer
form for later passes to choke on. also fixed cp0 to print the correct
name for cpvalid when it does this.
cpvalid.ss, cp0.ss,
misc.ms
- updated the prototype for s_ee_write_char to match the definition
expeditor.c
- fixed a side-effect preservation bug with non-trivial test-context
not-like patterns.
cp0.ss,
cp0.ms, 4.ms
- instead of default-exception handler, new-cafe establishes a handler
that calls the current value of base-exception-handler so the handler
can be overridden, as we do in our own make files.
cafe.ss,
7.ms
- fixed a bug in case and exclusive-cond syntax-error calls causing an
exception in syntax-error instead of the intended error message.
syntax.ss
- added tests for the case and exclusive-cond syntax-error calls
4.ms, root-experr-compile-0-f-f-f
- added print-extended-identifiers parameter. when #t, symbols like
1+ and +++ print without escapes.
priminfo.ss, print.ss,
6.ms
- added descriptions of print-extended-identifiers to the user's guide
and release notes. updated the release notes to account for a couple
of other log entries.
release_notes.stex,
intro.stex, io.stex
- updated the sockets example to work with the current version of Chez.
Change the foreign procedure definitions to use the more portable int
rather than integer-32. Switch to a custom port
[make-custom-binary-input/output-port] rather than a generic port
[make-input/output-port], which resulted in deleting quite a bit of
code. Fix various compiler warnings in the C code, and along the way,
fix a signedness bug in c_write that could have resulted in not writing
the full buffer (but reporting that it did) in the case of errors from
write.
examples/csocket.c, examples/socket.ss
- use high-precision clock time on Windows 8 and up
c/stats.c
- fixed profiling code that keyed profiling locations off of only the
bfp to instead key off of both the bfp and efp.
pdhtml.ss
- added Windows installer using the WiX Toolset
BUILDING, install/* (new)
- fix typo in ordinal format for 12
format.ss,
format.ms
- renamed install directory to wininstall to avoid conflict with
top-level Makefile
BUILDING, install/* (removed), wininstall/* (new)
- updated zlib to version 1.2.11
configure
- added procedure-arity-mask to report the allowed argument counts of
a compiled function. On a procedure from interpret or from one of
the trace procedures or syntactic forms, procedure-arity-mask
may report counts that are not actually allowed by the source
procedure.
cmacros.ss, compile.ss, cpnanopass.ss, mkheader.ss, primdata.ss,
prims.ss, strip.ss,
fasl.c, gc.c, globals.h, prim.c, prim5.c, scheme.c, schsig.c,
misc.ms, root-experr*,
objects.stex
- for non-win32 systems, now setting al register to a count of the
floating-point register arguments as required for varargs functions
by the System V ABI.
x86_64.ss,
foreign.ms
- added a missing quote mark in new printf mat Windows case
foreign.ms
- added travis-ci automation script and a 'partialx' testing target to
allow us to perform more than a single run of testing without running
afoul of travis-ci's 50-minute build timeout. 'partialx' tests six
of the twelve configurations tested by 'allx'.
.travis.yml (new),
mats/Mf-base
- paired the 'partialx' down to just four test configurations, with one
interpreter run, to try to get the threaded builds into line with
travis-ci's timeout.
mats/Mf-base
- eliminated some direct assumptions that a vector's type/length field
is a fixnum and added meta-asserts to verify that it is in a couple of
others, to facilitate future changes to vector typing. vectors are
now treated essentially like fxvectors, strings, and bytevectors.
cmacros.ss, cpnanopass.ss, prims.ss, mkheader.ss,
alloc.c, gc.c, scheme.c
- fixed a few comments to refer to scheme.c rather than main.c
externs.h, globals.h, thread.c
- for 64-bit Windows systems, now copying foreign-procedure
double-precision floating-point register arguments to integer
registers as required for varargs functions. Windows does not
support single-precision floating-point arguments as varargs.
foreign.ms, np-languages.ss, x86_64.ss
- added an optional timeout argument to condition-wait
externs.h, stats.c, thread.c, thread.h, csug/threads.stex,
primvars.ms, thread.ms, release_notes.stex,
date.ss, primdata.ss, prims.ss
- added immutable strings, vectors, fxvector, bytevectors, and boxes
5_4.ss, 5_6.ss, bytevector.ss, cmacros.ss, cpnanopass.ss,
fasl.ss, library.ss, mkheader.ss, primdata.ss, prims.ss,
externs.h, types.h, alloc.c, fasl.c, gc.c, scheme.c,
5_5.ms, 5_6.ms, bytevector.ms, misc.ms, root-experr*
objects.stex
- various tweaks to the immutable object support; also taught cp0
to simplify ($fxu< (most-positive-fixnum) e) => (fx< e 0) so we
don't have any incentive in special casing length checks where
the maximum length happens to be (most-positive-fixnum).
5_4.ss, 5_6.ss, bytevector.ss, cmacros.ss, cp0.ss, cpnanopass.ss,
mkheader.ss, primdata.ss, prims.ss,
fasl.c, gc.c, types.h
root-experr*, patch*
- generated bytevector=? procedure now gets out quickly on eq
arguments. cp0 optimizes away a number of additional equality
operations at optimize-level 3 (including bytevector=?) when
applied to the same variable references, as it already did for
eq?, eqv?, and equal?, at all optimize levels.
cpnanopass.ss, cp0.ss, primdata.ss,
cp0.ms
- updated bullyx patches
patch*
- updated release notes and tweaked user's guide.
release-notes.stex, objects.stex
- fixed typo: fxvector-immutable-flag used in place of
bytevector-immutable-flag in computation of type-immutable-bytevector
cmacros.ss
- reallocated typed-object types, using previously unused tag #b010
for strings and giving bytevectors both #b001 and #b101 (the
latter for immutable bytevectors) so that the maximum bytevector
length on 32-bit machines is once again the most-positive fixnum.
treating bytevectors rather than strings or fxvectors (or even
vectors) special in this regard is appropriate since the maximum
number of bytes in a bytevector is maximum-length x 1 rather than
maximum-length x 4 for strings, fxvectors, and vectors on 32-bit
machines. with this change on 32-bit machines, a vector can
occupy up to 1/2 of virtual memory, strings and fxvectors 1/4,
and bytevectors 1/8.
cmacros.ss
- added record-type-equal-procedure, record-type-hash-procedure,
record-equal-procedure, and record-hash-procedure to enable
per-type customization of the behavior of equal? and equal-hash
for a record value
5_1.ss, newhash.ss, primdata.ss,
record.ms, root-experr*,
objects.stex
- adding dropped changes
record.ss,
root-experr*
- added entry for record-type-equal-procedure and friends
release_notes.stex
- changed copyright year to 2017
7.ss, scheme.1.in, comments of many files
- expanded the CSUG description of the handling of command-line
arguments not recognized as standard options and added a description
of the same to the COMMAND-LINE OPTIONS section of the man page.
did a bit of minor cleanup elsewhere in the man page.
use.stex, scheme.1.in
- destroy_thread now processes guardian entries
thread.c, 4.ms, release_notes.stex
- mutexes and conditions are now freed when no longer used via
$close-resurrected-mutexes&conditions, $keep-live primitive added
externs.h, prim5.c, thread.c, 4.ms, thread.ms, release_notes.stex,
7.ss, cpnanopass.ss, np-languages.ss, primdata.ss, prims.ss
- fix reduction for map and for-each with optimization level 3
to drop the expression, check that procedure has the correct
arity and is discardable or unsafe.
Also add a simplification for for-each with empty lists
with optimization level 2.
cp0.ss, 4.ms, primdata.ss
- fix invalid memory reference when enum-set-indexer procedure is not
passed a symbol
enum.ss, enum.ms, root-experr*, release_notes.stex
- fix overflow detection for fxsll, fxarithmetic-shift-left, and
fxarithmetic-shift
library.ss, fx.ms, release_notes.stex
- added ephemeron pairs and changed weak hashtables to use
ephemeron pairs for key--value mapping to avoid the key-in-value
problem
prims.ss, primdata.ss, newhash.ss, fasl.ss, mkheader.ss
cmacro.ss, prim5.c, fasl.c, gc.c, gcwrapper.c, types.h,
4.ms, hash.ms, objects.stex, smgmt.stex, csug.bib
- check_dirty_ephemeron now puts ephemerons whose keys haven't yet
been seen on the pending list rather than the trigger lists.
gc.c
- removed scan of space_ephemeron from check_heap because check_heap
as written can't handle the two link fields properly.
gcwrapper.c
- in the ephemerons mat that checks interaction between mutation and
collection, added generation arguments to the first two collect
calls so they always collect into the intended generation.
4.ms
- updated allx and bullyx patches
patch*
- fix strip-fasl-file for immutable strings and vectors,
fix an $oops call, and fix a vector-index increment in hashing
strip.ss, 7.ss, newhash.ss, misc.ms
- fix signature of fxbit-set?
primdata.ss
- more optimizations for map and for-each with explicit list
extend the reductions for map and for-each when the arguments are
explicit lists like (list 1 2 3 ...) or '(1 2 3 ...).
cp0.ss,
4.ms
- reverted to the preceding version of cp0 due to failure to preserve
the expected evaluation order in one of the mats; removed the
corresponding equivalent-expansion tests.
cp0.ss,
4.ms
- restored the map and for-each optimizations with a fix for the
evaluation-order bug.
cp0.ss,
4.ms
- added date-dst? to access the previously-hidden DST information in
date records, and added date-zone-name to provide a time zone name.
date.ss, primdata.ss,
stats.c,
date.ms, root-experr*, patch-compile*,
system.stex
- fixed a bug in flonum-extractor, which on 64-bit machines was using an
8-byte read instead of a 4-byte read to pick up the 4 highest-order
bytes of a little-endian flonum, potentially reading past the end of
mapped memory for flonums produced by taking the imaginary part of an
inexact complexnum (which, unlike other flonums, are not aligned on
16-byte boundaries). The 8-byte load would also have failed to produce
correct results on 64-bit big-endian machines (of which we presently
have none) because the offsets passed to flonum-extractor assume the
bits are in the lowest-order 4 bytes of the extracted field.
cp0.ss,
misc.ms,
release_notes.stex

locate-source-object-source function that uses the new components,
a current-locate-source-object-source parameter to control looking up
line and column information, a current-make-source-object parameter to
control location recording, an optional use-cache argument to

- added support for Microsoft Visual Studio 2017 on Windows
BUILDING, c/Mf-a6nt, c/Mf-ta6nt, c/vs.bat,
mats/Mf-a6nt, mats/Mf-ta6nt, mats/ftype.ms
- added support for building Windows installs with Bash/WSL
wininstall/Makefile, candle.bat, light.bat
- added support for building with Visual Studio 2017's BuildTools
c/vs.bat
- check for git before using to get submodules
configure
- fixed windows installer failure when vcredist is not preinstalled by
using the vcredist merge module, split the 32 and 64 bit MSIs and
added a wix bundle to combine the MSIs into a single exe installer,
added a batch script for locating Visual Studio's vcredist merge
modules, updated installer paths and names.

- the $case macro used by r6rs:case and case now unconditionally trims
redundant keys and expands into exclusive-cond rather than cond.
it catches references to => before expanding into exclusive-cond
to avoid supporting => as an undocumented and useless extension
of the case syntax. the r6rs:case and case macros now require
multiple clauses rather than leaving the enforcement to exclusive-cond,
and the exclusive-cond macro now requires multiple clauses rather
than leaving the enforcement to cond.
syntax.ss,

- ifdef'd out include of xlocale.h for glibc, since the glibc
locale.h includes xlocale.h or, in glibc 2.26, its replacement.
expeditor.c
- Updated CSUG to replace \INSERTREVISIONMONTHSPACEYEAR with the current
month and year at the time of generation.
csug.stex, copyright.stex

make files, and updated distclean target to remove these files.
configure, makefiles/Makefile-csug.in (renamed from csug/Makefile),

- added pass-time tracking for pre-cpnanopass passes to compile.
compile.ss
- added inline handler for fxdiv-and-mod
cp0.ss, primdata.ss
- changed order in which return-point operations are done (adjust
sfp first, then store return values, then restore local saves) to
avoid storing return values to homes beyond the end of the stack
in cases where adjusting sfp might result in a call to dooverflood.
cpnanopass.ss, np-languages.ss
- removed unused {make-,}asm-return-registers bindings
cpnanopass.ss
- corrected the max-fv value field of the lambda produced by the
hand-coded bytevector=? handler.
cpnanopass.ss
- reduced live-pointer and inspector free-variable mask computation
overhead
cpnanopass.ss
- moved regvec cset copies to driver so they aren't copied each
time a uvar is assigned to a register. removed checks for
missing register csets, since registers always have csets.
cpnanopass.ss
- added closure-rep else clause in record-inspector-information!.
cpnanopass.ss
- augmented tree representation with a constant representation
for full trees to reduce the overhead of manipulating trees or
subtrees with all bits set.
cpnanopass.ss
- tree-for-each now takes start and end offsets; this cuts the
cost of traversing and applying the action when the range of
applicable offsets is other than 0..tree-size.
cpnanopass.ss
- introduced the notion of poison variables to reduce the cost of
register/frame allocation for procedures with large sets of local
variables. When the number of local variables exceeds a given
limit (currently hardwired to 1000), each variable with a large
live range is considered poison. A reasonable set of variables
with large live ranges (the set of poison variables) is computed
by successive approximation to avoid excessive overhead. Poison
variables directly conflict with all spillables, and all non-poison
spillables indirectly conflict with all poison spillables through
a shared poison-cset. Thus poison variables cannot live in the
same location as any other variable, i.e., they poison the location.
Conflicts between frame locations and poison variables are handled
normally, which allows poison variables to be assigned to
move-related frame homes. Poison variables are spilled prior to
register allocation, so conflicts between registers and poison
variables are not represented. move relations between poison
variables and frame variables are recorded as usual, but other
move relations involving poison variables are not recorded.
cpnanopass.ss, np-languages.ss
- changed the way a uvar's degree is decremented by remove-victim!.
instead of checking for a conflict between each pair of victim
and keeper and decrementing when the conflict is found, remove-victim!
now decrements the degree of each var in each victim's conflict
set. while this might decrement other victims' degrees unnecessarily,
it can be much less expensive when large numbers of variables are
involved, since the number of conflicts between two non-poison
variables should be small due to the selection process for
(non-)poison variables and the fact that the unspillables introduced
by instruction selection should also have few conflicts. That
is, it reduces the worst-case complexity of decrementing degrees
from O(n^2) to O(n).
cpnanopass.ss
- took advice in compute-degree! comment to increment the uvars in
each registers csets rather than looping over the registers for
each uvar asking whether the register conflicts with the uvar.
cpnanopass.ss
- assign-new-frame! now zeros out save-weight for local saves, since
once they are explicitly saved and restored, they are no longer
call-live and thus have no save cost.

- updated newrelease to handle mats/Mf-*nt
newrelease mats/Mf-a6nt mats/Mf-i3nt mats/Mf-ta6nt mats/Mf-ti3nt
- fixed gather-filedata's sort of profile entries. for any two
entries x and y in the list produced by the sort call, if x's
bfp = y's bfp, x should come before y if x's efp < y's efp.
The idea is that enclosing entries should always come later
in the list. this affects only languages where two expressions
can start at the same character position.
pdhtml.ss
- expanded capability of ez-grammar with support for simple
parsing of binary operators w/precedence and associativity
and automatically generated markdown grammar descriptions.
ez-grammar-test.ss now also doubles as a test of pdhtml for
algebraic languages.
mats/examples.ms,
examples/ez-grammar.ss, examples/ez-grammar-test.ss,

- maybe-compile-{file,program,library} and automatic import
compilation now treat a malformed object file as if it were
not present and needs to be regenerated. A malformed object
file (particularly a truncated one) might occur if the compiling
processes is killed or aborts before it has a chance to delete
a partial object file.

primdata.ss
- more staid and consistent Mf-cross main target
Mf-cross
- cpletrec now replaces the incoming prelexes with new ones so
that it doesn't have to alter the flags on the incoming ones, since
the same expander output is passed through the compiler twice while
compiling a file with macro definitions or libraries. we were
getting away without this just by luck.
cpletrec.ss
- pure? and ivory? now return #t for a primref only if the prim is
declared to be a proc, since some non-proc prims are mutable, e.g.,
$active-threads and $collect-request-pending.
cp0.ss
- $error-handling-mode? and $eol-style? are now properly declared to
be procs rather than system state variables.
primdata.ss
- the new pass $check-prelex-flags verifies that prelex referenced,
multiply-referenced, and assigned flags are set when they
should be. (it doesn't, however, complain if a flag is set
when it need not be.) when the new system parameter
$enable-check-prelex-flags is set, $check-prelex-flags is
called after each major pass that produces Lsrc forms to verify
that the flags are set correctly in the output of the pass.
this parameter is unset by default but set when running the
mats.
cprep.ss, back.ss, compile.ss, primdata.ss,
mats/Mf-base
- removed the unnecessary set of prelex referenced flag from the
build-ref routines when we've just established that it is set.
syntax.ss, compile.ss
- equivalent-expansion? now prints differences to the current output
port to aid in debugging.
mat.ss
- the nanopass that patches calls to library globals into calls to
their local counterparts during whole-program optimization now
creates new prelexes and sets the prelex referenced, multiply
referenced, and assigned flags on the new prelexes rather than
destructively setting flags on the incoming prelexes. The
only known problems this fixes are (1) the multiply referenced
flag was not previously being set for cross-library calls when
it should have been, resulting in overly aggressive inlining
of library exports during whole-program optimization, and (2)
the referenced flag could sometimes be set for library exports
that aren't actually used in the final program, which could
prevent some unreachable code from being eliminated.
compile.ss
- added support for specifying default record-equal and
record-hash procedures.
primdata.ss, cmacros.ss, cpnanopass.ss, prims.ss, newhash.ss,
gc.c,
record.ms
- added missing call to relocate for subset-mode tc field, which
wasn't burning us because the only valid non-false value, the
symbol system, is in the static generation after the initial heap
compaction.
gc.c
- added a lambda-commonization pass that runs after the other
source optimizations, particularly inlining, and a new parameter
that controls how hard it works. the value of commonization-level
ranges from 0 through 9, with 0 disabling commonization and 9
maximizing it. The default value is 0 (disabled). At present,
for non-zero level n, the commonizer attempts to commonize
lambda expressions consisting of 2^(10-n) or more nodes.
commonization of one or more lambda expressions requires that
they have identical structure down to the leaf nodes for quote
expressions, references to unassigned variables, and primitives.
So that various downstream optimizations aren't disabled, there
are some additional restrictions, the most important of which
being that call-position expressions must be identical. The
commonizer works by abstracting the code into a helper that
takes the values of the differing leaf nodes as arguments.
the name of the helper is formed by concatenating the names of
the original procedures, separated by '&', and this is the name
that will show up in a stack trace. The source location will
be that of one of the original procedures. Profiling inhibits
commonization, because commonization requires profile source
locations to be identical.
cpcommonize.ss (new), compile.ss, interpret.ss, cprep.ss,
primdata.ss, s/Mf-base,
mats/Mf-base
- cpletrec now always produces a letrec rather than a let for
single immutable lambda bindings, even when not recursive, for
consistent expand/optimize output whether the commonizer is
run or not.
cpletrec.ss,
record.ms
- trans-make-ftype-pointer no longer generates a call to
$verify-ftype-address if the address expression is a call to
ftype-pointer-address.
ftype.ss
- Remove special case for (#2%map p '()) in cp0
so the reduced version checks that p is a procedure.
Also make the same change for #2%for-each.

- added identifier? checks to detect attempts to use non-identifier
field names in define-record-type field specs.
syntax.ss,
record.ms, root-experr*
- fixed an issue with the library system where an exception that occurs
during visit or revisit left the library in an inconsistent state that
caused it to appear that it was still in the process of running. This
manifested in it raising a cyclic dependency exception, even though
there really is not a cyclic dependency. The various library
management functions involved will now reset the part of the library
when an exception occurs. This also means that if the library visit
or revisit failed for a transient reason (such as a missing or
incorrect library version that can be fixed by updating the
library-directories) it is now possible to recover from these errors.

- when thread_get_room exhausts the local allocation area, it now
goes through a common path with S_get_more_room to allocate a new

the use of global allocation (and the number of tc mutex acquires
in threaded builds) when a lot of small objects are allocated by
C code with no intervening Scheme-side allocation or dirty writes.
alloc.c, types.h, externs.h

one of the first base fields in the case of unions) of which must
be a word-sized integer with native endianness representing a
reference count. ftype pointers are registered with and retrieved
from the guardian just like objects are registered with and
retrieved from any guardian. the difference is that the garbage
collector decrements the reference count before resurrecting an
ftype pointer and resurrects only those whose reference counts
become zero, i.e., are ready for deallocation.

- the compiler now generates better inline code for the bytevector
procedure. instead of one byte memory write for each argument,
it writes up to 4 (32-bit machines) or 8 (64-bit machines) bytes

fewer writes.
cpnanopass.ss,

libraries.stex
- added fix for whole program/library compilation bug with help from
@owaddell who originally reported the problem in issue 386. this bug
arises from the way the parts of the combined library, and their
binary dependencies, are invoked when one of the constituent libraries
is invoked. consider, for example, a combined library that contains
(A) and (B), where (B) depends on a binary library (C). depending on
the sort order of (A) and (B), which may be unconstrained in the
partial ordering established by library dependencies, invoking (A) may
result in the invoke code for (B) being run first, without (B) ever
being explicitly invoked. this can result in bindings required from
(C) by the invoke code in (B) to be unbound. even in the case where
(A) comes before (B) in the topological sort, if they are combined
into the same cluster, (B)'s invoke code will be run as part of
invoking (A). the solution is two part: first we extend the invoke
requirements of the first library in the cluster to include the binary
libraries that precede it in the topological sort and add a dependency
on the first library in the cluster to all of the other libraries in
the cluster. this means no matter which library in the cluster is
invoked first, it will cause the first library to be invoked, in turn
ensuring the binary libraries that precede it are invoked. when there
are multiple clusters, a dependency is added from each cluster to the
first library in the cluster that precedes it. this ensures that
invoking a library in a later cluster first, will still cause all of
the dependencies of the previous clusters to be invoked. ultimately,
these extra dependencies enforce an ordering on the invocation of the
source and binary libraries that matches the topological sort, even if
the topological sort was under constrained. to maintain the property
that import requirements are a superset of the invoke and visit
requirements, we also extend the import requirements to include the
extended invoke requirements. the import requirements are also added
to the dependency graph to further constrain the topological sort and
ensure that we do not introduce artificial cycles in the import graph.

and make file for creating OSX packages via "make create-pkg".
bintar (removed), bintar/Makefile (new), rpm/Makefile (new),
pkg/Makefile (new), pkg/rmpkg (new), workarea, checkin, newrelease,
Makefile.in, Makefile-workarea.in.
- improved error message for compile-whole-program and
compile-whole-library when a top-level expression is discovered while
processing a wpo file.
compile.ss

- fixed a bug in the fasl representation and reading of mutually
recursive ftypes where one of the members of the cycle is the
parent of another, which manifested in the fasl reader raising
bogus "incompatible record type" exceptions. (The bug could also
affect other record-type descriptors with cycles involving parent
rtds and "extra" fields.) object files created before this fix
are incompatible with builds with this fix, and objects files
created after this fix are incompatible builds without this fix.

printed, which is useful for debugging

- added compress-level parameter to select a compression level for
file writing and changed the default for lz4 compression to do a
better job compressing. finished splitting glz input routines
apart from glz output routines and did a bit of other restructuring.
removed gzxfile struct-as-bytevector wrapper and moved its fd
into glzFile. moved DEACTIVATE to before glzdopen_input calls
in S_new_open_input_fd and S_compress_input_fd, since glzdopen_input
reads from the file and could block. the compress format and now
level are now recorded directly the thread context. replaced
as-gz? flag bit in compressed bytevector header word with a small
number of bits recording the compression format at the bottom of
the header word. flushed a couple of bytevector compression mats
that depended on the old representation. (these last few changes
should make adding new compression formats easier.) added
s-directory build options to choose whether to compress and, if
so, the format and level.

- improved the effectiveness of LZ4 boot-file compression to within
15% of gzip by increasing the lz4 output-port in_buffer size to
1<<18. With the previous size (1<<14) LZ4-compressed boot files
were about 50% larger. set the lz4 input-port in_buffer and
out_buffer sizes to 1<<12 and 1<<14. there's no clear win at
present for larger input-port buffer sizes.
compress-io.c
- To reduce the memory hit for the increased output-port in_buffer
size and the corresponding increase in computed out_buffer size,
one output-side out_buffer is now allocated (lazily) per thread
and stored in the thread context. The other buffers are now
directly a part of the lz4File_out and lz4File_in structures
rather than allocated separately.
compress-io.c, scheme.c, gc.c,
cmacros.ss
- split out the buffer emit code from glzwrite_lz4 into a
separate glzemit_lz4 helper that is now also used by gzclose
so we can avoid dealing with a NULL buffer in glzwrite_lz4.
glzwrite_lz4 also uses it to writing large buffers directly and
avoid the memcpy.
compress-io.c
- replaced lz4File_out and lz4File_in mode enumeration with the
compress format and inputp boolean. using switch to check and
raising exceptions for unexpected values to further simplify
adding new compression formats in the future.
compress-io.c
- replaced the never-defined struct lz4File pointer in glzFile
union with the more specific struct lz4File_in_r and Lz4File_out_r
pointers.
compress-io.h, compress-io.c
- added free of lz4 structures to gzclose. also changed file-close
logic generally so that (1) port is marked closed before anything is
freed to avoid dangling pointers in the case of an interrupt or
error, and (2) structures are freed even in the case of a write
or close error, before the error is reported. also now mallocing
glz and lz4 structures after possibility of errors have passed where
possible and freeing them when not.
compress-io.c,
io.ss
- added return-value checks to malloc calls and to a couple of other
C-library calls.
compress-io.c
- corrected EINTR checks to look at errno rather than return codes.
compress-io.c
- added S_ prefixes to the glz* exports
externs.h, compress-io.c, new-io.c, scheme.c, fasl.c
- added entries for mutex-name and mutex-thread
threads.stex
- fix record-ref reduction in cp0
in expressions like
(record-ref ... (begin (newline) (record ...)))
the reduction was dropping the possible side effect expressions
in this case the (newline).
cp0.ss
- zero?, fxzero?, positive?, fxpositive?, etc., now go through
(a suitably modified) relop-length so that, for example,
(zero? (length x)) results in the same code as (null? x). added
correctness tests for these and all of the other predicates that
go through relop-length.
cpnanopass.ss, 5_2.ms
- assertion-violationf and friends now show the who, message, and
irritants in the original call when who or message is found not to
be of the right type.

- annotations are now preserved in object files for debug
only, for profiling only, for both, or not at all, depending
on the settings of generate-inspector-information and
compile-profile. in particular, when inspector information
is not enabled but profiling is, source information does
not leak into error messages and inspector output, though it is
still available via the profile tools. The mechanics of this
involved repurposing the fasl a? parameter to hold an annotation
flags value when it is not #f and remaking annotations with
new flags if necessary before emitting them.
compile.ss, fasl.ss, misc.ms
- altered a number of mats to produce correct results even
when the 's' directory is profiled.
misc.ms, cp0.ms, record.ms
- profile-release-counters is now generation-friendly; that is,
it doesn't look for dropped code objects in generations that have
not been collected since the last call to profile-release-counters.
also, it no longer allocates memory when it releases counters.
pdhtml.ss,
gc.c, gcwrapper.c, globals.h, prim5.c
- removed unused entry points S_ifile, S_ofile, and S_iofile
alloc.c, externs.h
- mats that test loading profile info into the compiler's database
to guide optimization now weed out preexisting entries, in case
the 's' directory is profiled.
4.ms, mat.ss, misc.ms, primvars.ms
- counters for dropped code objects are now released at the start
of each mat group.
mat.ss
- replaced ehc (enable-heap-check) option with hci (heap-check-interval)
option that allows heap checks to be performed periodically rather
than on each collection. hci=0 is equivalent to ehc=f (disabling
heap checks) and hci=1 is equivalent to ehc=t (enabling heap
checks every collection), while hci=100 enables heap checks only
every 100th collection. allx and bullyx mats use this feature
to reduce heap-checking overhead to a more reasonable level. this
is particularly important when the 's' directory is profiled,
since the amount of static memory to be checked is greatly increased
due to the counters.
mats/Mf-base, mat.ss, primvars.ms
- added a mat that calls #%show-allocation, which was otherwise not
being tested.
misc.ms
- removed a broken primvars mat and updated two others. in each case,
the mat was looking for information about primitives in the wrong
(i.e., old) place and silently succeeding when it didn't find any
primitives to test. the revised mats (along with a few others) now
check to make sure at least one identifier has the information they
look for. the removed mat was checking for library information that
is now compiled in, so the mat is now unnecessary. the others were
(not) doing argument-error checks. fixing these turned up a handful of
problems that have also been fixed: a couple of unbound variables in the
mat driver, two broken primdata declarations, a tardy argument check
by profile-load-data, and a bug in char-ready?, which was requiring
an argument rather than defaulting it to the current input port.
primdata.ss, pdhtml.ss, io.ms,
primdvars.ms, 4.ms, 6.ms, misc.ms, patch*
- added initial support for recording coverage information. when the
new parameter generate-covin-files is set, the compiler generates
.covin files containing the universe of all source objects for which
profile forms are present in the expander output. when profiling
and generation of covin files are enabled in the 's' directory, the
mats optionally generate .covout files for each mat file giving
the subset of the universe covered by the mat file, along with an
all.covout in each mat output directory aggregating the coverage
for the directory and another all.covout in the top-level mat
directory aggregating the coverage for all directories.
back.ss, compile.ss, cprep.ss, primdata.ss, s/Mf-base,
mat.ss, mats/Mf-base, mats/primvars.ms
- support for generating covout files is now built in. with-coverage-output
gathers and dumps coverage information, and aggregate-coverage-output
combines (aggregates) covout files.
pdhtml.ss, primdata.ss, compile.ss,
mat.ss, mats/Mf-base, primvars.ms
- profile-clear now adjusts active coverage trackers to avoid losing
coverage information.
pdhtml.ss,
prim5.c
- nested with-coverage calls are now supported.
pdhtml.ss
- switched to a more compact representation for covin and covout files;
reduces disk space (compressed or not) by about a factor of four
and read time by about a factor of two with no increase in write time.
primdata.ss, pdhtml.ss, cprep.ss, compile.ss,
mat.ss, mats/Mf-base
- added support for determining coverage for an entire run, including
coverage for expressions hit during boot time. 'all' mats now produce
run.covout files in each output directory, and 'allx' mats produce
an aggregate run.covout file in the mat directory.
pdhtml.ss,
mat.ss, mats/Mf-base
- profile-release-counters now adjusts active coverage trackers to
account for the counters that have been released.
pdhtml.ss,
prim5.c
- replaced the artificial "examples" target with a real "build-examples"
target so make won't think it always has to mats that depend upon
the examples directory having been compiled. mats make clean now
runs make clean in the examples directory.
mats/Mf-base
- importing a library from an object file now just visits the object
file rather than doing a full load so that the run-time code for
the library is not retained. The run-time code is still read
because the current fasl format forces the entire file to be read,
but not retaining the code can lower heap size and garbage-collection
cost, particularly when many object-code libraries are imported.
The downside is that the file must be revisited if the run-time
code turns out to be required. This change exposed several
places where the code was failing to check if a revisit is needed.
syntax.ss,
7.ms, 8.ms, misc.ms, root-experr*
- fixed typos: was passing unquoted load rather than quoted load
to $load-library along one path (where it is loading source code
and therefore irrelevant), and was reporting src-path rather than
obj-path in a message about failing to define a library.
syntax.ss
- compile-file and friends now put all recompile information in
the first fasl object after the header so the library manager can
find it without loading the entire fasl file. The library manager
now does so. It also now checks to see if library object files
need to be recreated before loading them rather than loading them and
possibly recompiling them after discovering they are out of date, since
the latter requires loading the full object file even if it's out of
date, while the former takes advantage of the ability to extract just
recompile information. as well as reducing overhead, this eliminates
possibly undesirable side effects, such as creation and registration
of out-of-date nongenerative record-type descriptors. because the
library manager expects to find recompile information at the front of
an object file, it will not find all recompile information if object
files are "catted" together. also, compile-file has to hold in memory
the object code for all expressions in the file so that it can emit the
unified recompile information, rather than writing to the object file
incrementally, which can significantly increase the memory required
to compile a large file full of individual top-level forms. This does
not affect top-level programs, which were already handled as a whole,
or a typical library file that contains just a single library form.
compile.ss, syntax.ss
- the library manager now checks include files before library dependencies
when compile-imported-libraries is false (as it already did when
compile-imported-libraries is true) in case a source change affects
the set of imported libraries. (A library change can affect the set
of include files as well, but checking dependencies before include
files can cause unneeded libraries to be loaded.) The include-file
check is based on recompile-info rather than dependencies, but the
library checks are still based on dependencies.
syntax.ss
- fixed check for binding of scheme-version. (the check prevents
premature treatment of recompile-info records as Lexpand forms
to be passed to $interpret-backend.)
scheme.c
- strip-fasl-file now preserves recompile-info when compile-time info
is stripped.
strip.ss
- removed include-req* from library/ct-info and ctdesc records; it
is no longer needed now that all recompile information is maintained
separately.
expand-lang.ss, syntax.ss, compile.ss, cprep.ss, syntax.ss
- changed the fasl format and reworked a lot of code in the expander,
compiler, fasl writer, and fasl reader to allow the fasl reader
to skip past run-time information when it isn't needed and
compile-time information when it isn't needed. Skipping past
still involves reading and decoding when encrypted, but the fasl
reader no longer parses or allocates code and data in the portions
to be skipped. Side effects of associating record uids with rtds
are also avoided, as are the side effects of interning symbols
present only in the skipped data. Skipping past code objects
also reduces or eliminates the need to synchronize data and
instruction caches. Since the fasl reader no longer returns
compile-time (visit) or run-time (revisit) code and data when not
needed, the fasl reader no longer wraps these objects in a pair
with a 0 or 1 visit or revisit marker. To support this change,
the fasl writer generates separate top-level fasl entries (and
graphs) for separate forms in the same top-level source form
(e.g., begin or library). This reliably breaks eq-ness of shared
structure across these forms, which was previously broken only
when visit or revisit code was loaded at different times (this
is an incompatible change). Because of the change, fasl "groups"
are no longer needed, so they are no longer handled.
7.ss, cmacros.ss, compile.ss, expand-lang.ss, strip.ss,
externs.h, fasl.c, scheme.c,
hash.ms
- the change above is surfaced in an optional fasl-read "situation"
argument (visit, revisit, or load). The default is load. visit
causes it to skip past revisit code and data; revisit causes it
to skip past visit code and data; and load causes it not to skip
past either. visit-revisit data produced by (eval-when (visit
revisit) ---) is never skipped.
7.ss, primdata.ss,
io.stex
- to improve compile-time and run-time error checking, the
Lexpand recompile-info, library/rt-info, library-ct-info, and
program-info forms have been replaced with list-structured forms,
e.g., (recompile-info ,rcinfo).
expand-lang.ss, compile.ss, cprep.ss, interpret.ss, syntax.ss
- added visit-compiled-from-port and revisit-compiled-from-port
to complement the existing load-compiled-from-port.
7.ss, primdata.ss,
7.ms,
system.stex
- increased amount read when seeking an lz4-compressed input
file from 32 to 1024 bytes at a time
compress-io.c
- replaced the fasl a? parameter value #t with an "all" flag value
so it's value is consistently a mask.
cmacros.ss, fasl.ss, compile.ss
- split off profile mats into a separate file
misc.ms, profile.ms (new), root-experr*, mats/Mf-base
- added coverage percent computations to mat allx/bullyx output
mat.ss, mats/Mf-base, primvars.ms
- replaced coverage tables with more generic and generally useful
source tables, which map source objects to arbitrary values.
pdhtml.ss, compile.ss, cprep.ss, primdata.ss,
mat.ss, mats/Mf-base, primvars.ms, profile.ms,
syntax.stex
- reduced profile counting overhead by using calls to fold-left
instead of calls to apply and map and by using fixnum operations
for profile counts on 64-bit machines.
pdhtml.ss
- used a critical section to fix a race condition in the calculations
of profile counts that sometimes resulted in bogus (including
negative) counts, especially when the 's' directory is profiled.
pdhtml.ss
- added discard flag to declaration for hashtable-size
primdata.ss
- redesigned the printed representation of source tables and rewrote
get-source-table! to read and store incrementally to reduce memory
overhead.
compile.ss
- added generate-covin-files to the set of parameters preserved
by compile-file, etc.
compile.ss,
system.stex
- moved covop argument before the undocumented machine and hostop
arguments to compile-port and compile-to-port. removed the
undocumented ofn argument from compile-to-port; using
(port-name ip) instead.
compile.ss, primdata.ss,
7.ms,
system.stex
- compile-port now tries to come up with a file position to supply
to make-read, which it can do if the port's positions are character
positions (presently string ports) or if the port is positioned
at zero.
compile.ss
- audited the argument-type-error fuzz mat exceptions and fixed a
host of problems this turned up (entries follow). added #f as
an invalid argument for every type for which #f is indeed invalid
to catch places where the maybe- prefix was missing on the argument
type. the mat tries hard to determine if the condition raised
(if any) as the result of an invalid argument is appropriate and
redirects the remainder to the mat-output (.mo) file prefixed
with 'Expected error', causing them to show up in the expected
error output so developers will be encouraged to audit them in
the future.
primvars.ms, mat.ss
- added an initial symbol? test on machine type names so we produce
an invalid machine type error message rather than something
confusing like "machine type #f is not supported".
compile.ss
- fixed declarations for many primitives that were specified as
accepting arguments of more general types than they actually
accept, such as number -> real for various numeric operations,
symbol -> endianness for various bytevector operations,
time -> time-utc for time-utc->date, and list -> list-of-string-pairs
for default-library-search-handler. also replaced some of the
sub-xxxx types with specific types such as sub-symbol -> endianness
in utf16->string, but only where they were causing issues with
the primvars argument-type-error fuzz mat. (this should be done
more generally.)
primdata.ss
- fixed incorrect who arguments (was map instead of fold-right,
current-date instead of time-utc->date); switched to using
define-who/set-who! generally.
4.ss, date.ss
- append! now checks all arguments before any mutation
5_2.ss
- with-source-path now properly supplies itself as who for the
string? argument check; callers like load now do their own checks.
7.ss
- added missing integer? check to $fold-bytevector-native-ref whose
lack could have resulted in a compile-time error.
cp0.ss
- fixed typo in output-port-buffer-mode error message
io.ss
- fixed who argument (was fx< rather than fx<?)
library.ss
- fixed declaration of first source-file-descriptor argument (was
sfd, now string)
primdata.ss
- added missing article 'a' in a few error messages
prims.ss
- fixed the copy-environment argument-type error message for the list
of symbols argument.
syntax.ss
- the environment procedure now catches exceptions that occur and
reraises the exception with itself as who if the condition isn't
already a who condition.
syntax.ss
- updated experr and allx patch files for changes to argument-count
fuzz mat and fixes for problems turned up by them.
root-experr*, patch*
- fixed a couple of issues setting port sizes: string and bytevector
output port put handlers don't need room to store the character
or byte, so they now set the size to the buffer length rather
than one less. binary-file-port-clear-output now sets the index
rather than size to zero; setting the size to zero is inappropriate
for some types of ports and could result in loss of buffering and
even suppression of future output. removed a couple of redundant
sets of the size that occur immediately after setting the buffer.
io.ss
- it is now possible to return from a call to with-profile-tracker
multiple times and not double-count (or worse) any counts.
pdhtml.ss, profile.ms
- read-token now requires a file position when it is handed a
source-file descriptor (since the source-file descriptor isn't
otherwise useful), and the source-file descriptor argument can
no longer be #f. the input file position plays the same role as
the input file position in get-datum/annotations. these extra
read-token arguments are now documented.
read.ss,
6.ms,
io.stex
- the source-file descriptor argument to get-datum/annotations can
no longer be #f. it was already documented that way.
read.ss
- read-token and do-read now look for the character-positions port
flag before asking if the port has port-position, since the latter
is slightly more expensive.
read.ss
- rd-error now reports the current port position if it can be determined
when fp isn't already set, i.e., when reading from a port without
character positions (presently any non string port) and fp has not
been passed in explicitly (to read-token or get-datum/annotations).
the port position might not be a character position, but it should be
better than nothing.
read.ss
- added comment noting an invariant for s_profile_release_counters.
prim5.c
- restored accidentally dropped fasl-write formdef and dropped
duplicate fasl-read formdef
io.stex
- added a 'coverage' target that tests the coverage of the Scheme-code
portions of Chez Scheme by the mats.
Makefile.in, Makefile-workarea.in
- added .PHONY declarations for all of the targets in the top-level
and workarea make files, and renamed the create-bintar, create-rpm,
and create-pkg targets bintar, rpm, and pkg.
Makefile.in, Makefile-workarea.in

primvars.ms
- used with-object-file to restore accidentally dropped close-port in
compile-whole-program and compile-whole-library
compile.ss
- initialized variable to enable compilation with gcc 9.1.0 at -O3
c/scheme.c

library-rt-info records in the code for compile-whole-xxx.
compile.ss,

- local-eval-hook now calls eval rather than interpret when profiling
is enabled, so local transformer code can be profiled.
syntax.ss,
profile.ms
- fix compiler bug related to call-with-values and a first argument
whose body result is compiled to an allocation, inline form, or
foreign call
cpnanopass.ss, 3.ms
- improved error reporting for library compilation-instance errors:
now including the name of the object file from which the "wrong"
compilation instance was loaded, if it was loaded from (or compiled
to) an object file and the original importing library, if it was
previously loaded from an object file due to a library import.
syntax.ss, 7.ss, interpret.ss,

smgmt.stex, threads.stex
- added verify-loadability. given a situation (visit, revisit,
or load) and zero or more pathnames (each of which may be optionally
paired with a library search path), verity-loadability checks
whether the set of object files named by those pathnames and any
additional object files required by library requirements in the
given situation can be loaded together. it raises an exception
in each case where actually attempting to load the files would
raise an exception and additionally in cases where loading files
would result in the compilation or loading of source files in
place of the object files. if the check is successful,
verity-loadability returns an unspecified value. in either case,
although portions of the object files are read, none of the
information read from the object files is retained, and none of
the object code is read, so there are no side effects other than
the file operations and possibly the raising of an exception.
library and program info records are now moved to the top of each
object file produced by one of the file compilation routines,
just after recompile info, with a marker to allow verity-loadability
to stop reading once it reads all such records. this change is
not entirely backward compatible; the repositioning of the records
can be detected by a call to list-library made from a loaded file
before the definition of one or more libraries. it is fully
backward compatible for typical library files that contain a
single library definition and nothing else. adding this feature
required changes to the object-file format and corresponding
changes in the compiler and library manager. it also required
moving cross-library optimization information from library/ct-info
records (which verity-loadability must read) to the invoke-code
for each library (which verity-loadability does not read) to
avoid reading and permanently associating record-type descriptors
in the code with their uids.
compile.ss, syntax.ss, expand-lang.ss, primdata.ss, 7.ss,
7.ms, misc.ms, root-experr*, patch*,

- fixed a bug that bit only with the compiler compiled at
optimize-level 2: add-library/rt-records was building a library/ct-info
wrapper rather than a library/rt-info wrapper.
compile.ss
- fixed a bug in visit-library that could result in an indefinite
recursion: it was not checking to make sure the call to $visit
actually added compile-time info to the libdesc record. it's not
clear, however, whether the libdesc record can be missing
compile-time information on entry to visit-library, so the code
that calls $visit (and now checks for compile-time information
having been added) might not be reachable. ditto for
revisit-library.
syntax.ss

- libraries contained within a whole program or library are now
marked pending before their invoke code is run so that invoke
cycles are reported as such rather than as attempts to invoke
while still loading.
compile.ss, syntax.ss, primdata.ss,
7.ms, root-experr*
- the library manager now protects against unbound references
from separately compiled libraries or programs to identifiers
ostensibly but not actually exported by (invisible) libraries
that exist only locally within a whole program. this is done by
marking the invisibility of the library in the library-info and
propagating it to libdesc records; the latter is checked upon
library import, visit, and invoke as well as by verify-loadability.
the import and visit code of each invisible no longer complains
about invisibility since it shouldn't be reachable.
syntax.ss, compile.ss, expand-lang.ss,
7.ms, 8.ms, root-experr*, patch*
- documented that compile-whole-xxx's linearization of the
library initialization code based on static dependencies might
not work for dynamic dependencies.
system.stex
- optimized bignum right shifts so the code (1) doesn't look at
shifted-off bigits if the bignum is positive, since it doesn't
need to know in that case if any bits are set; (2) doesn't look
at shifted-off bigits if the bignum is negative if it determines
that at least one bit is set in the bits shifted off the low-order
partially retained bigit; (3) quits looking, if it must look, for
one bits as soon as it finds one; (4) looks from both ends under
the assumption that set bits, if any, are most likely to be found
toward the high or low end of the bignum rather than just in the
middle; and (5) doesn't copy the retained bigits and then shift;
rather shifts as it copies. This leads to dramatic improvements
when the shift count is large and often significant improvements
otherwise.
number.c,
5_3.ms,
release_notes.stex
- threaded tc argument through to all calls to S_bignum and
S_trunc_rem so they don't have to call get_thread_context()
when it might already have been called.
alloc.c, number.c, fasl.c, print.c, prim5.c, externs.h
- added an expand-primitive handler to partially inline integer?.
cpnanopass.ss
- added some special cases for basic arithmetic operations (+, -, *,
/, quotient, remainder, and the div/div0/mod/mod0 operations) to
avoid doing unnecessary work for large bignums when the result
will be zero (e.g,. multiplying by 0), the same as one of the
inputs (e.g., adding 0 or multiplying by 1), or the additive
inverse of one of the inputs (e.g., subtracting from 0, dividing
by -1). This can have a major beneficial affect when operating
on large bignums in the cases handled. also converted some uses
of / into integer/ where going through the former would just add
overhead without the possibility of optimization.
5_3.ss,
number.c, externs.h, prim5.c,
5_3.ms, root-experr, patch*,

- added a queue to hold pending signals for which handlers have
been registered via register-signal-handler so up to 63 (configurable

- bytevector-compress now selects the level of compression based
on the compress-level parameter. Prior to this it always used a
default setting for compression. the compress-level parameter
can now take on the new minimum in addition to low, medium, high,
and maximum. minimum is presently treated the same as low
except in the case of lz4 bytevector compression, where it
results in the use of LZ4_compress_default rather than the
slower but more effective LZ4_compress_HC.

primdata.ss
- console I/O on Windows now supports Unicode characters in the BMP
expeditor.c, new-io.c, release_notes.stex
- the collector now releases bignum temporaries in the collector
rather than relocating them so we don't keep around huge bignum
temporaries forever.
gc.c
- removed the presumably useless vector-handling code from load()
which used to be required to handle fasl groups.
scheme.c
- object files are no longer compressed as a whole, and the parameter
compile-compressed is no longer defined. instead, the individual
fasl objects within an object file are compressed whenever the
new parameter fasl-compressed is set to its default value, #t.
this allows the fasl reader to seek past portions of an object
file that are not of interest, i.e., visit-only code and data
when "revisiting" an object file and revisit-only code and data
when "visiting" an object file. the compressed portions are
compressed using the format and level specified by the compress-format
and compress-level parameters. the C-coded fasl reader and
boot-file loader no longer handle compressed files; these are
handled, less efficiently, by the Scheme entry point (fasl-read).
a warning exception is raised the first time a program attempts
to create or read a compressed fasl file.

- added begin wrappers around many of the Scheme source files that
contained multiple expressions to cut down the number of top-level
fasl objects and increase compressibility. also removed the
string filenames for debugging at the start of each file that had
one---these are best inserted universally by a modified compile-file
during a debugging session when desired. also removed unnecessary
top-level placeholder definitions for the assignments that follow.

- fixed build on Linux with musl libc
expeditor.c
- extended primitive folding to primitives that return multiple
values.
cp0.ss, primdata.ss,
cp0.ms
- fix handling of calling code's address for locking around a callable
that has a u8*, u16*, or u32* argument, which could cause the
cp register copy in the thread context to be changed before
S_call_help gets it
cpnanopass.ss, schlib.c, foreign2.c, foreign.ms
- the collector now promotes objects one generation higher at a time
by default. previously, it promoted every live oldspace object to
the selected target generation, which could result in objects
prematurely skipping one or more generations and thus being
retained longer than their ages justify. the biggest cost in
terms of code complexity and performance is the recording of
pointers from older newspace objects to younger newspace objects
that could not previously occur.
gc.c, alloc.c, externs.h
- the collect procedure now takes an additional optional minimum
target generation argument to allow the new default behavior to
be overridden.
7.ss, primdata.ss,
gcwrapper.c,
7.ms, root-experr*
- added cn flag to control collect-notify
mats/Mf-base
- resweep_weak_pairs now sets sweep_loc to orig_next_loc rather than
first_loc since the latter could result in unnecessary sweeping of
existing target-generation weak pairs.
gc.c
- added set of S_child_processes[newg] to S_child_processes[oldg]
in S_do_gc code handling decreases in the maximum generation.
gcwrapper.c
- a specialized variant of the collector is used in the common case
where the max copied generation is 0, the min and max target
generations are 1, and there are no locked generation 0 objects
is now used. with the default collection parameters and no locking
of generation 0 objects, these collections account for 3/4 of all
collections.
gc.c, gc-011.c (new), gcwrapper.c, externs.h, c/Mf-base
- maybe-fire-collector no longer tries to be so precise and instead
just counts the number of generation-bytes allocated since the
last gc. surprisingly, rebuilding the s directory requires about
the same number of collections with this coarser (and less
expensive) measurement. this change also fixes a problem with
too-frequent collections when the maximum-generation is set to
zero. to make the determination even less expensive, a running
total of bytes in each generation is now maintained in a new
bytes_of_generation vector, and maybe-fire-collector is no longer
called when the collector is running.
alloc.c, gc.c, gcwrapper.c, globals.h
- copy now copies two pairs at once only if they are in the same
segment, which saves a few memory references and tests and turns
out not to reduce the number of opportunities significantly in
tested programs.
gc.c
- occupied_segments, first_loc, base_loc, next_loc, bytes_left,
bytes_of_space, sweep_loc, and orig_next_loc are now indexed
by [g][s] rather than [s][g] to improve locality in the default
(and common) case where there are only a handful of active
generations.
globals.h, types.h, segment.c, gc.c, gcwrapper.c, prim5.c
- documented change to collect procedure
smgmt.stex, release_notes.stex
- now maintaining 16-byte architectural stack alignment (if the
incoming stack is so aligned) on all x86 platforms except
i3nt/ti3nt. more recent versions of gcc sometimes generate sse
instructions that require 16-byte stack alignment.
x86.ss

print.ss,
record.ms, root-experr*
- now using 64-bit arithmetic for seconds in S_condition_wait to
prevent a potential 2038 bug, at least on platforms where time_t
is 64 bits. also now rounding rather than truncating nanoseconds
in the conversion to milliseconds on Windows.
thread.c
- fixed a bug in arm32 that caused an error when generating
instructions with immediate operands where the immediate was larger
than 8 bits.
arm32.ss

non-ftype syntactic binding for the type exists. for instance, if a
syntactic binding for integer-32 is introduced which is not bound to
an ftd, using integer-32 in the context of an ftype will still work.
this change also allows an ftype binding to be created for a native
