For non-Altivec compiles when we emit ROP mitigation instructions, we use a default offset of zero which corresponds to the backchain save location which will get clobbered on any call. The fix is to compute the ROP hash save location for all compiles. 2024-06-14 Peter Bergner <berg...@linux.ibm.com> gcc/ PR target/115389 * config/rs6000/rs6000-logue.cc (rs6000_stack_info): Compute rop_hash_save_offset for non-Altivec compiles. gcc/testsuite PR target/115389 * gcc.target/powerpc/pr115389.c: New test.
