* gcse.c: Update comment at top.
Update comment on mem handling.
mem_last_set, mem_first_set, mem_set_in_block: gone.
Declaration of reg_set_info: gone.
(oprs_unchanged_p): Don't use mem_*set_* anymore. They are
pointless with load_killed_in_block_p (they are *more*
conservative then it, not less, and less accurate).
(oprs_not_set_p): Ditto.
(alloc_gcse_mem): Don't allocate mem_set_in_block
(free_gcse_mem): Don't free it, either.
(record_last_mem_set_info): Update comment in front, remove
mem_*set_* stuff. Note the reason we don't handle stores directly
here.
(compute_hash_table): Update comments to reflect reality. Remove
mem_*set_* references.
(reset_opr_set_tables): Remove mem_*set_* references.
(mark_call): Ditto.
(mark_set): Ditto. Also remove double sets of bitmaps for REG's.
(mark_clobber): Ditto (on both parts, we double set here too).
(expr_killed_p): Remove mem_set_in_block test.
(compute_transp): Remove mem_set_in_block test.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
