Wilco <wilco at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Assignee|unassigned at gcc dot gnu.org |wilco at gcc dot gnu.org --- Comment #6 from Wilco <wilco at gcc dot gnu.org> --- So the issue is that AArch64 return address signing was using the loc.offset field which is now uninitialized. The fix is to check for REG_UNSAVED first and use that to initialize the offset. I'm testing a patch.
