Subject: [Bug target/107678] [13 Regression] Segfault in aarch64_fallback_frame_state when running SVE code
Date: Mon, 14 Nov 2022 17:45:03 +0000 [thread overview]
Message-ID: <bug-107678-4-KubC03Xc0T@http.gcc.gnu.org/bugzilla/> (raw)
In-Reply-To: <bug-107678-4@http.gcc.gnu.org/bugzilla/>
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107678
--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note aarch64_fallback_frame_state segfault is
if (pc[0] != MOVZ_X8_8B || pc[1] != SVC_0)
pc comes from:
unsigned *pc = context->ra;
>so the size of the vectors could be a hint?
It is not in this case.
But it might be a hint on maybe the dwarf2 stack unwinding output is not fully
correct for non-constant offsets ...
