--- Comment #10 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:455f165fd86f50163d2147b669edcc2e9bf5b0f8 commit r8-10867-g455f165fd86f50163d2147b669edcc2e9bf5b0f8 Author: Jakub Jelinek <ja...@redhat.com> Date: Fri Dec 4 12:18:21 2020 +0100 debug: Fix another vector DECL_MODE ICE [PR98100] The PR88587 fix changes DECL_MODE of vars with vector type during inlining/cloning when the vars are copied, so that their DECL_MODE matches their TYPE_MODE in the new function. Unfortunately, the following testcase still ICEs, the var isn't really used in the new function and so it isn't copied, but becomes just a nonlocalized var. So we can't adjust its DECL_MODE because it appears in multiple functions and needs different modes in between them. The following patch changes the DEBUG_INSN creation to use TYPE_MODE instead of DECL_MODE for vars with vector types. 2020-12-04 Jakub Jelinek <ja...@redhat.com> PR target/98100 * cfgexpand.c (expand_gimple_basic_block): For vars with vector type, use TYPE_MODE rather than DECL_MODE. * gcc.target/i386/pr98100.c: New test.
