--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:2472dcaa8cb9e02e902f83d419c3ee7e0f3d9041 commit r12-7513-g2472dcaa8cb9e02e902f83d419c3ee7e0f3d9041 Author: Jakub Jelinek <ja...@redhat.com> Date: Mon Mar 7 11:14:04 2022 +0100 s390: Fix up *cmp_and_trap_unsigned_int<mode> constraints [PR104775] The following testcase fails to assemble due to clgte %r6,0(%r1,%r10) insn not being accepted by assembler. My rough understanding is that in the RSY-b insn format the spot in other formats used for index registers is used instead for M3 what kind of comparison it is, so this patch follows what other similar instructions use for constraint (i.e. one without index register). 2022-03-07 Jakub Jelinek <ja...@redhat.com> PR target/104775 * config/s390/s390.md (*cmp_and_trap_unsigned_int<mode>): Use S constraint instead of T in the last alternative. * gcc.target/s390/pr104775.c: New test.
