- 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.

- Separate 64 and 32 bit MSIs
- Add wix bundle to combine MSIs into single installer
- Use basic wix UI
- Use merge modules to install vcredist package
- Add script to locate vcredist merge modules
- Fix installer status text by adding WixUI_ErrorProgressText ref
Merge modules seems to be the preferred method for installing the
redistributable package, which should decrease the package size and
speed up installation. This commit also addresses a bug where the
installer does not work when VC redistributable is not already
installed.
The 32 and 64 bit components were split into separate MSIs because
Windows Installer only officially supports packages containing a
single architecture. A package bundle is then created containing both
MSIs so only a single file needs to be distributed.
There seemed to be no trivial way to get the path to the vcredist
merge modules bundled with visual studio so I added a script
(locate-vcredist.bat) that handles this. It will need to be updated in
the future for compatibility with newer VS platform toolsets.
Some paths and name were changed, here's a summary:
32-bit install path: C:\Program Files (x86)\Chez Scheme 9.4.1\
64-bit install path: C:\Program Files\Chez Scheme 9.4.1\
installer file name: ChezScheme.exe

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.

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.

Check both the beginning file pointer (bfp) and end file pointer (efp)
of the source location associated with a profile counter when updating
its count.
Assuming that each expression has a unique bfp with respect to profiling
seems to give accurate execution counts for s-expression-based source
locations as in Scheme, but causes problems when targeting other kinds
of syntax. For instance, a C-style function call, referencing the called
function by name, such as "fn(arg)", can logically have profile counters
associated with 1) the function name reference ("fn") and 2) the entire
function call expression ("fn(arg)"), both of which begin at the same
source location. Only the bfp is checked when updating profile counters,
so the two source locations are conflated, and only one counter is
incremented, which gives inaccurate execution counts for both locations;
approximately twice as many for one, and zero for the other.

original commit: 0a6a1e14e7ecb9e39fa7a10a8584ed2fec24cbf4
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.

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@<a> and <m>@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 actually produces a number. added some related new tests,
including several found lacking by profiling. added a couple of
checks to number->string whose absence 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 pdtml flag, which if set to t causes profile-dump-html to be
called at the end of a mat run.

"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.

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 writeable.
6.ms
original commit: b90a037c9fac18fdcbce73a42f28940e85a6c07b
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.
