OFFSET_TYPE is signed though, so unlike POINTER_TYPE/REFERENCE_TYPE it can also trigger with the x < 0 && y < 0 && z < 0 to (x | y | z) < 0 optimization. 2022-09-27 Jakub Jelinek <jakub@redhat.com> PR tree-optimization/107029 * tree-ssa-reassoc.cc (optimize_range_tests_cmp_bitwise): Treat OFFSET_TYPE like POINTER_TYPE, except that OFFSET_TYPE may be signed and so can trigger even the (b % 4) == 3 case. * g++.dg/torture/pr107029.C: New test. ^ permalink raw reply [flat|nested] 5+ messages in thread
