The following patch fixes that. Didn't use INTEGRAL_TYPE_P because bswapping bools is just too weird. 2020-03-31 Jakub Jelinek <ja...@redhat.com> PR tree-optimization/94403 * gimple-ssa-store-merging.c (verify_symbolic_number_p): Allow also ENUMERAL_TYPE lhs_type. * g++.dg/tree-ssa/pr94403.C: New test.
