--- Comment #9 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Kewen Lin <li...@gcc.gnu.org>: https://gcc.gnu.org/g:c7f17493cc26a4395d549547075603a15f4c94a7 commit r12-8846-gc7f17493cc26a4395d549547075603a15f4c94a7 Author: Kewen Lin <li...@linux.ibm.com> Date: Mon Sep 26 00:33:18 2022 -0500 rs6000: Fix the condition with frame_pointer_needed_indeed [PR96072] As PR96072 shows, the code adding REG_CFA_DEF_CFA reg note makes one assumption that we have emitted one insn which restores the frame pointer previously. That part of code was guarded with flag frame_pointer_needed before, it was consistent, but it was replaced with flag frame_pointer_needed_indeed since commit r10-7981. It caused ICE due to unexpected NULL insn. PR target/96072 gcc/ChangeLog: * config/rs6000/rs6000-logue.cc (rs6000_emit_epilogue): Update the condition for adding REG_CFA_DEF_CFA reg note with frame_pointer_needed_indeed. gcc/testsuite/ChangeLog: * gcc.target/powerpc/pr96072.c: New test. (cherry picked from commit 5be0950d22209f5ba69d244387228e12389a8470)
