--- Comment #7 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-8 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:3549a5cabdfd4ebb197da99f247d0abad0ba55b5 commit r8-10455-g3549a5cabdfd4ebb197da99f247d0abad0ba55b5 Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Mar 3 10:42:34 2020 +0100 explow: Fix ICE caused by plus_constant [PR94002] The following testcase ICEs in cross to riscv64-linux. The problem is that we have a DImode integral constant (that doesn't fit into SImode), which is pushed into a constant pool and later access just the first half of it using a MEM. When plus_constant is called on such a MEM, if the constant has mode, we verify the mode, but if it doesn't, we don't and ICE later on when we think the CONST_INT is a valid SImode constant. 2020-03-03 Jakub Jelinek <ja...@redhat.com> PR rtl-optimization/94002 * explow.c (plus_constant): Punt if cst has VOIDmode and get_pool_mode is different from mode. * gcc.dg/pr94002.c: New test. (cherry picked from commit e913d4f4771e04d4254bf6c0e720fec5e324a898)
