[Bug rtl-optimization/45136] -fcompare-debug failure with -Os -fschedule-insns

[jakub at gcc dot gnu dot org]

------- Comment #5 from jakub at gcc dot gnu dot org  2010-07-30 09:40 -------
Confirmed, this seems to be sched1 fault.
In bb5 we have 2 normal insns, followed by (-g only) a debug_insn, followed by
two NOTE_INSN_DELETED created by combine (do we ever remove these from the
IL?),
followed again (-g only) by debug_insn and then other insns.
sched1 moves those two NOTE_INSN_DELETED in -g case to the start of the block,
keeps them where they were otherwise.

Alex, can you please have a look?
