The test case is simulated from primal_bea_mpp of 429.mcf. gcc version 7.0.0 20161106 ---- snip from test.c.155t.ifcvt---- ;; basic block 30, loop depth 1, count 0, freq 407, maybe hot ;; prev block 29, next block 31, flags: (NEW, REACHABLE, VISITED) ;; pred: 28 [64.0%] (FALSE_VALUE,EXECUTABLE) _96 = _67 == 2; _29 = if_conversion_var_66 > 0; _12 = _96 & _29; <== Non canonical gimple if (_12 != 0) goto <bb 31>; else goto <bb 32>; -----snip ends-----
