bbro pass is blindly changing: (jump_insn 55 57 23 2 pr44546.c:10 (set (pc) (if_then_else (unle (reg:CCFP 17 flags) (const_int 0 [0])) (label_ref:SI 28) (pc))) 576 {*jcc_1} (expr_list:REG_DEAD (reg:CCFP 17 flags) (expr_list:REG_BR_PROB (const_int 7929 [0x1ef9]) (nil))) to (jump_insn 55 57 28 2 pr44546.c:10 (set (pc) (if_then_else (gt (reg:CCFP 17 flags) (const_int 0 [0])) (label_ref:SI 89) (pc))) 576 {*jcc_1} (expr_list:REG_DEAD (reg:CCFP 17 flags) (expr_list:REG_BR_PROB (const_int 2071 [0x817]) (nil))) This is not valid insn, since GT condition does not satisfy ix86_trivial_fp_comparison_operator predicate. -- ubizjak at gmail dot com changed: What |Removed |Added ---------------------------------------------------------------------------- Known to fail|4.5.0 |4.5.0 4.6.0 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44546
