--- Comment #11 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:ce8325e77d923a11dce089a7ef3a24b4737bf95f commit r8-10466-gce8325e77d923a11dce089a7ef3a24b4737bf95f Author: Jakub Jelinek <ja...@redhat.com> Date: Fri Mar 13 11:33:16 2020 +0100 aarch64: Fix another bug in aarch64_add_offset_1 [PR94121] > I'm getting this ICE with -mabi=ilp32: > > during RTL pass: fwprop1 > /opt/gcc/gcc-20200312/gcc/testsuite/gcc.dg/pr94121.c: In function 'bar': > /opt/gcc/gcc-20200312/gcc/testsuite/gcc.dg/pr94121.c:16:1: internal compiler error: in decompose, at rtl.h:2279 That is a preexisting issue, caused by another bug in the same function. When mode is SImode and moffset is 0x80000000 (or anything else with the bit 31 set), we need to sign-extend it. 2020-03-13 Jakub Jelinek <ja...@redhat.com> PR target/94121 * config/aarch64/aarch64.c (aarch64_add_offset_1): Use gen_int_mode instead of GEN_INT. (cherry picked from commit c2f836c413b1e9ae45598338b4a2ecd33bd926fb)
