--- Comment #15 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Kewen Lin <li...@gcc.gnu.org>: https://gcc.gnu.org/g:f0b38334c57a8e92139c22efa82fe96994bb8eb8 commit r11-11074-gf0b38334c57a8e92139c22efa82fe96994bb8eb8 Author: Kewen Lin <li...@linux.ibm.com> Date: Thu Oct 12 00:05:03 2023 -0500 rs6000: Make 32 bit stack_protect support prefixed insn [PR111367] As PR111367 shows, with prefixed insn supported, some of checkings consider it's able to leverage prefixed insn for stack protect related load/store, but since we don't actually change the emitted assembly for 32 bit, it can cause the assembler error as exposed. Mike's commit r10-4547-gce6a6c007e5a98 has already handled the 64 bit case (DImode), this patch is to treat the 32 bit case (SImode) by making use of mode iterator P and ptrload attribute iterator, also fixes the constraints to match the emitted operand formats.
