--- Comment #9 from Uroš Bizjak <ubizjak at gmail dot com> --- Created attachment 41826 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=41826&action=edit Adjust INCOMING_FRAME_SP_OFFSET for TYPE_EXCEPTION functions How about something like attached patch? The patch adjusts INCOMING_FRAME_SP_OFFSET of an exception handler to 2 * UNITS_PER_WORD. The resulting code reads: .cfi_startproc subq $392, %rsp .cfi_def_cfa_offset 400 fxsave64 -120(%rsp) addq $400, %rsp .cfi_def_cfa_offset 0 iretq .cfi_endproc Patch is otherwise untested. Probably, function argument parsing code has to be adjusted as well. I'm also not sure if all .cfi directives are correct.
