Since memory reference rtx may trap, this patch is to ensure we copy REG_EH_REGION reg_note while replacing swapped aligned load or store. PR target/106091 gcc/ChangeLog: * config/rs6000/rs6000-p8swap.cc (replace_swapped_aligned_store): Copy REG_EH_REGION when replacing one store insn having it. (replace_swapped_aligned_load): Likewise. gcc/testsuite/ChangeLog: * gcc.target/powerpc/pr106091.c: New test.
