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. --- gcc/config/aarch64/aarch64.cc | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/gcc/config/aarch64/aarch64.cc b/gcc/config/aarch64/aarch64.cc index 36cd172d182..afdbf4213c1 100644 --- a/gcc/config/aarch64/aarch64.cc +++ b/gcc/config/aarch64/aarch64.cc @@ -8417,8 +8417,7 @@ aarch64_output_probe_sve_stack_clash (rtx base, rtx adjustment, static bool aarch64_needs_frame_chain (void) { - /* Force a frame chain for EH returns so the return address is at FP+8. */ - if (frame_pointer_needed || crtl->calls_eh_return) + if (frame_pointer_needed) return true; /* A leaf function cannot have calls or write LR. */ -- 2.25.1
