--- Comment #13 from Andrey Belevantsev <abel at gcc dot gnu.org> 2012-07-20 09:13:28 UTC ---
The ia64 backend disallows any movements of instructions that depend on a
speculated insns with always returning false in insn_can_be_in_speculative_p,
and this later fails the ia64_speculate_insn hook.  Thus, sel-sched is likely
wrong to move this insn, I will take a look on Monday.
