exposed the default-library-search-handler and a library-search-handler
parameter to permit more control over the search for libraries during
import, compile-whole-library, and compile-whole-program

controversial, unless I damaged something in the process of integrating
them with other recent changes. the user's guide and release notes
have been updated as well to reflect the changes of interest to end
users.
- the body of load-library is now wrapped in a $pass-time with
to show the time spent loading libraries separately from the time
spent in expand.
syntax.ss
- interpret now plays the pass-time game
interpret.ss
- added compile-time-value? predicate and
compile-time-value-value accessor
syntax.ss, primdata.ss,
8.ms, primvars.ms, root-experr*
- $pass-stats now returns accurrate stats for the currently timed
pass.
7.ss
- compile-whole-program and compile-whole-library now propagate
recompile info from the named wpo file to the object file
to support maybe-compile-program and maybe-compile-library in
the case where compile-whole-{program,library} overwrites the
original object file.
compile.ss,
7.ms, mat.ss, primvars.ms
- replaced the ancient and unusable bintar with one that creates
a useful tarball for binary installs
bintar
- generated Mf-install InstallBin (InstallLib, InstallMan) now
correctly indirects through InstallPrefix if the --installbin
(--installlib, --installman) configure flag is not present.
src/configure
- removed definition of generate-procedure-source-information
patch.ss
- guardian tconc cells are now allocated in generation 0 in the hope
that they can be released more quickly.
gc.c
- added ftype-guardian syntax: (ftype-guardian A) creates a new
guardian for ftype pointers of type A, the first base field (or
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.
ftype.ss, cp0.ss, cmacros.ss, cpnanopass.ss, prims.ss, primdata.ss,
gc.c,
4.ms, root-experr*
- fixed a bug in automatic recompilation handling of missing include
files specified with absolute pathnames or pathnames starting with
"./" or "..": was erroring out in file-modification-time with a
file-not-found or other exception rather than recompiling.
syntax.ss,
7.ms, root-experr*, patch*
- changed inline vector-for-each and string-for-each code to
put the last call to the procedure in tail position, as was
already done for the library definitions and for the inline
code for for-each.
cp0.ss,
5_4.ms, 5_6.ms
- 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
at a time, which almost always results in fewer instructions and
fewer writes.
cpnanopass.ss,
bytevector.ms
- packaged unchanging implicit reader arguments into a single record
to reduce the number of arguments.
read.ss
- recoded run-vector to handle zero-length vectors. it appears
we're not presently generating empty vectors (representing empty
groups), but the fasl format permits them.
7.ss
original commit: 7be1d190de7171f74a1ee71e348d3e6310392686
Add a parameter to constrain the compiler (off by default) to
implement `+`, `*`, and variants as left-associative when given
multiple arguments.
original commit: d126ba3364893e66263c65af1cd6dbdd8b021439
reclaimed by the collector and must be released explicitly by the
programmer via (profile-release-counters).
pdhtml.ss, primdata.ss,
globals.h, externs.h, fasl.c, prim5.c, prim.c, alloc.c, scheme.c,
misc.ms,
release_notes.stex, system.stex
original commit: 68e20f721618dbaf4c1634067c2bee24a493a750
Also adds `get-initial-thread`, since threa values are useful with
`compute-size[-increments]`.
Changes the compiler to inline `weak-pair?` and `ephemeron-pair?`,
since that provides better performance for `compute-size-increments`.
original commit: 57d0cc13f8e932972cba3837b4f54e9c86786091
updated descriptions of standard-input-port and standard-output-port;
fixed a missing "and" in the description of utf-16-codec,
original commit: a5db479b68b74dda9f62665c44cfad2b1baf322e
The `object-references` function is intended to support debugging of
memory leaks by providing a mapping from each live object to the
object that retained it.
original commit: 61f6602b7e6c388c529f3c5995dcf71a7c42e005
A program can use `make-arity-wrapper-procedure` to synthesize a
function that reports a given arity mask (without calling `compile`).
In addition, `set-arity-wrapper-procedure!` suports modifying the
implementation of a synthesized procedure. Although similar
functionality could be achieved with `(lambda args (apply (unbox proc)
args))`, an arity wrapper procedure can dispatch to another procedure
without allocating a list for the arguments.
The interpreter now uses an internal variant of arity wrappers to
cooperate with `procedure-arity-mask`.
