* bootstrap/Makefile.am (GUILE_OPTIMIZATIONS): Change to just -O1.
* module/language/tree-il/spec.scm (choose-compiler): Use CPS for -O2
and higher.
* module/system/base/optimize.scm (available-optimizations): CPS for -O2
and higher, but -Oresolve-primitives now at -O1 also.
* module/language/tree-il/analyze.scm (make-analyzer): Expect an int for
optimization level.
* module/scripts/compile.scm (%options, show-warning-help): No more
-Wnone / Wall; use -W0 or -W9 instead.
* module/system/base/compile.scm (level-validator): Validate small int.
(compute-analyzer, add-default-optimizations): Likewise.
* test-suite/tests/optargs.test (without-compiler-warnings):
* test-suite/tests/tree-il.test (call-with-warnings): Parameterize level
to 0, not #f.
* bootstrap/Makefile.am (GUILE_WARNINGS): Use -W0, not -Wnone.
* am/guilec (GUILE_WARNINGS):
* am/bootstrap.am (GUILE_WARNINGS): Explictly default to -W1.
* bootstrap/Makefile.am (GUILE_WARNINGS): Set to -Wnone, as the meaning
of "no -W flags" has changed to be effectively -W1.
* module/scripts/compile.scm (%options): Adapt to parse -Wnone, -W2, and
so on.
(parse-args): Default to (default-warning-level).
(show-warning-help): Add more warning help.
(compile): Pass #:warning-level.
* bootstrap/Makefile.am: Build both eval.go and psyntax-pp.go before
the rest of the .go files so that they are handled by a fast macro
expander. This saves time for a parallel build.
* am/bootstrap.am: New file, factored out of bootstrap/Makefile.am.
* bootstrap/Makefile.am: Use bootstrap.am.
* prebuilt/Makefile.am:
* prebuilt/i686-pc-linux-gnu/Makefile.am:
* prebuilt/mips-unknown-linux-gnu/Makefile.am:
* prebuilt/x86_64-unknown-linux-gnu/Makefile.am: New files.
* configure.ac: Output the prebuilt/ makefiles.
* Makefile.am: Descend into prebuilt/ when making dist.
* meta/uninstalled-env.in: Arrange to put prebuilt/ in the beginning of
the GUILE_LOAD_COMPILED_PATH. Also fix a case where bootstrap/ wasn't
being correctly added to the load path.
* bootstrap/Makefile.am: Don't serialize the build through
psyntax-pp.scm. On a multicore make, this will result in higher total
CPU time as multiple processes use an interpreted expander, but lower
total build time, as all processes will take approximately the same
time to load and run the compiler.
* module/language/cps/specialize-numbers.scm: New pass, to turn "add"
into "fadd", and similarly for sub, mul, and div.
* module/language/cps/optimize.scm:
* module/Makefile.am:
* bootstrap/Makefile.am: Wire up the new pass.
* bootstrap/Makefile.am (.scm.go): Fix -L options to point to /module.
(SOURCES): Move up psyntax-pp.scm. Sadly a bug while I was developing
the bootstrap makefile meant that there was a stale psyntax-pp.go from
module/ that the build was picking up, leading to invalid
bootstrap timing measurements.
This reduces total build time to around 30 minutes or so.
* Makefile.am (SUBDIRS): Visit bootstrap/ before module/.
* bootstrap/Makefile.am: New file.
* configure.ac: Generate bootstrap/Makefile.
* meta/uninstalled-env.in (top_builddir): Add bootstrap/ to the
GUILE_LOAD_COMPILED_PATH.
* module/Makefile.am: Simplify to just sort files in alphabetical order;
since bootstrap/ was already compiled, we don't need to try to
optimize compilation order. Although the compiler will get faster as
more of the compiler itself is optimized, this isn't a significant
enough effect to worry about.
