--- Comment #2 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Sandiford <rsand...@gcc.gnu.org>: https://gcc.gnu.org/g:248e357f6941fe9409658386dc9b86b75dfd96c6 commit r11-269-g248e357f6941fe9409658386dc9b86b75dfd96c6 Author: Fei Yang <felix.y...@huawei.com> Date: Mon May 11 15:18:47 2020 +0100 aarch64: Fix ICE when expanding scalar floating move with -mgeneral-regs-only. [PR94991] In the testcase for PR94991, we are doing FAIL for scalar floating move expand pattern since TARGET_FLOAT is false with option -mgeneral-regs-only. But move expand pattern cannot fail. It would be better to replace the FAIL with code that bitcasts to the equivalent integer mode using gen_lowpart. 2020-05-11 Felix Yang <felix.y...@huawei.com> gcc/ PR target/94991 * config/aarch64/aarch64.md (mov<mode>): Bitcasts to the equivalent integer mode using gen_lowpart instead of doing FAIL for scalar floating point move. gcc/testsuite/ PR target/94991 * gcc.target/aarch64/mgeneral-regs_5.c: New test.
