Handling byteswapping of pointers is easy, all we need is to allow them, for the __builtin_bswap* we already use TYPE_PRECISION to determine the precision and we cast the operand and result to the correct type if they aren't uselessly convertible to what the builtin expects. 2021-04-01 Jakub Jelinek <ja...@redhat.com> PR tree-optimization/96573 * gimple-ssa-store-merging.c (init_symbolic_number): Handle also pointer types. * gcc.dg/pr96573.c: New test.
