Subject: (sched_analyze): Record NOTE_INSN_SETJMP if no CALL_INSN as prev;
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e6e68157d3ff41c37a736656e4f093a41d7c3e28;p=gcc.git

(sched_analyze): Record NOTE_INSN_SETJMP if no CALL_INSN as prev;

preserve CONST_CALL_P bit.
(reemit_notes): Restore CONST_CALL_P.
