GCC 4.3.3 is being released, adjusting target milestone.
This may be more a change than is acceptable right now for 4.4. If so
I will sit on this patch until 4.5 opens up. The patch is basically a
complete rewrite of the part of invoke.texi that deals with dump options
for the rtl pass. This section had badly rotted.
I started from a grep of the sources looking for rtl_opt_pass and
documented all of the passes that i found in mostly alphabetical
order. Where the old version documented several passes together, I
kept that unless things had changed. In total there were about a half
dozen passes that were no longer there and about a dozen new passes that
had not been documented.
I did make some changes in the code, which is the reason that this may
not be acceptable to 4.4. The changes are pretty harmless: all of them
involve either removing the pass name or changing it.
1) Pass names that contained dashes had the dashes changed to
underscores. About half used slashes and half underscores and I went
with underscores to avoid a possible ambiguity with the options parsing.
2) I also removed the pass name from 6 passes that do not print anything
or dump the code.
I think this change is agains what was asked for in the past. We want to have
pass names for all passes.
3) Files that contained multiple passes with names of the form xx,
xx2... were renamed xx1,xx2.
This later change causes a test suit failure which was fixed.
All of these changes are pretty minor. The only possible failure these
can cause are in the test suite where dump files are scanned.
I tested this on x86 and ppc both 32 and 64. It is possible that there
are platform specific regression tests that scan for dump files that
were not caught on these four targets.
I also left in lreg and greg.These are at the end and need to be
deleted along with those passes.
I have enclosed a copy of the new text. The diff is unreadable.
ok for 4.4 or should i wait for 4.5?
This is ok for 4.4 if you remove the parts that remove pass names. Please
wait a day for comments from others.
Thanks,
Richard.
I put those pass names back, but I documented them as producing no
output. I also removed the lreg and greg part since the RA removal
patch has been approved.
