--- Comment #20 from Jakub Jelinek <jakub at gcc dot gnu.org> --- -O3 -g testcase from PR64817 showing probably the same issue as #c0 with reorder_operands reverted: int a, b, d; void foo (void) { for (b = 0; b < 9; b++) { int e; for (d = 0; d < 5; d++) { a &= 231; a ^= 14; } a ^= 1; e = (a < 0) + a; } }
