From: Szabolcs Nagy <nsz@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc(refs/vendors/ARM/heads/gcs-13)] aarch64: Do not force a stack frame for EH returns Date: Wed, 14 Feb 2024 15:35:11 +0000 (GMT) [thread overview] Message-ID: <20240214153511.64020385E456@sourceware.org> (raw) https://gcc.gnu.org/g:f6d55bdfef950282f2fc2a15dbda3dbfd324e876 commit f6d55bdfef950282f2fc2a15dbda3dbfd324e876 Author: Szabolcs Nagy <szabolcs.nagy@arm.com> Date: Tue May 9 11:07:05 2023 +0100 aarch64: Do not force a stack frame for EH returns EH returns no longer rely on clobbering the return address on the stack so forcing a stack frame is not necessary. This does not actually change the code gen for the unwinder since there are calls before the EH return. gcc/ChangeLog: * config/aarch64/aarch64.cc (aarch64_needs_frame_chain): Do not force frame chain for eh_return.
