commonizatio pass and support for specifying default record
equal and hash procedures:
- 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.

- 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.

- fixed substring-fill! and vector-fill! to return void, reflecting the
documented return value of unspecified value. Also changes substring-fill!
to use define-who instead of repeating 'substring-fill! in all the error
messages.
5_4.ss, 5_6.ss
original commit: 3f65788b5422693f3648a9e2fe575f464eb31ccd
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.

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 simpl
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.
