--- Comment #9 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Vladimir Makarov <vmaka...@gcc.gnu.org>: https://gcc.gnu.org/g:df66fa08578a28b3acc8bdb6257b68c245a6a0fa commit r14-5333-gdf66fa08578a28b3acc8bdb6257b68c245a6a0fa Author: Vladimir N. Makarov <vmaka...@redhat.com> Date: Fri Nov 10 11:14:46 2023 -0500 [IRA]: Check autoinc and memory address after temporary equivalence substitution My previous RA patches to take register equivalence into account do temporary register equivalence substitution to find out that the equivalence can be consumed by insns. The insn with the substitution is checked on validity using target-depended code. This code expects that autoinc operations work on register but this register can be substituted by equivalent memory. The patch fixes this problem. The patch also adds checking that the substitution can be consumed in memory address too. gcc/ChangeLog: PR target/112337 * ira-costs.cc: (validate_autoinc_and_mem_addr_p): New function. (equiv_can_be_consumed_p): Use it. gcc/testsuite/ChangeLog: PR target/112337 * gcc.target/arm/pr112337.c: New.
