Rozycki <ma...@gcc.gnu.org>: https://gcc.gnu.org/g:3cf0e6ab2aa9e7cb9a406079ff19856a6461d9f0 commit r15-6833-g3cf0e6ab2aa9e7cb9a406079ff19856a6461d9f0 Author: Maciej W. Rozycki <ma...@orcam.me.uk> Date: Sun Jan 12 16:48:53 2025 +0000 Alpha: Restore frame pointer last in `builtin_longjmp' [PR64242] Add similar arrangements to `builtin_longjmp' for Alpha as with commit 71b144289c1c ("re PR middle-end/64242 (Longjmp expansion incorrect)") and commit 511ed59d0b04 ("Fix PR64242 - Longjmp expansion incorrect"), so as to restore the frame pointer last, so that accesses to a local buffer supplied can still be fulfilled with memory accesses via the original frame pointer, fixing: FAIL: gcc.c-torture/execute/pr64242.c -O0 execution test FAIL: gcc.c-torture/execute/pr64242.c -O1 execution test FAIL: gcc.c-torture/execute/pr64242.c -O2 execution test FAIL: gcc.c-torture/execute/pr64242.c -O3 -g execution test FAIL: gcc.c-torture/execute/pr64242.c -Os execution test FAIL: gcc.c-torture/execute/pr64242.c -O2 -flto -fno-use-linker-plugin -flto-partition=none execution test FAIL: gcc.c-torture/execute/pr64242.c -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects execution test and adding no regressions in `alpha-linux-gnu' testing. gcc/ PR middle-end/64242 * config/alpha/alpha.md (`builtin_longjmp'): Restore frame pointer last. Add frame clobber and schedule blockage.
