--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Hans-Peter Nilsson <h...@gcc.gnu.org>: https://gcc.gnu.org/g:9a2ae08b02d185a11e3e525e100ba637ce81c7ff commit r11-2050-g9a2ae08b02d185a11e3e525e100ba637ce81c7ff Author: Hans-Peter Nilsson <h...@axis.com> Date: Sun Jul 12 18:41:25 2020 +0200 cris: Add new pass eliminating compares after delay-slot-filling Delayed-branch-slot-filling a.k.a. reorg or dbr, often causes opportunities for more compare-elimination than were visible for the cmpelim pass. With cc0, these were caught by the elimination pass run in "final", thus the missed opportunities is a regression. A simple reorg-aware pass run just after reorg handles most of them, if not all. I chose to keep the "mach2" pass identifier string I copy-pasted from the SPARC port instead of inventing one like "postdbr_cmpelim". Note the gap in numbers in the test-case file names. gcc: PR target/93372 * config/cris/cris-passes.def: New file. * config/cris/t-cris (PASSES_EXTRA): Add cris-passes.def. * config/cris/cris.c: Add infrastructure bits and pass execute function cris_postdbr_cmpelim. * config/cris/cris-protos.h (make_pass_cris_postdbr_cmpelim): Declare. gcc/testsuite: * gcc.target/cris/pr93372-44.c, gcc.target/cris/pr93372-46.c: New.
