--- Comment #7 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:1a132c4d7cdb22cbab85b8596418daa2c3157812 commit r11-7295-g1a132c4d7cdb22cbab85b8596418daa2c3157812 Author: Jakub Jelinek <ja...@redhat.com> Date: Fri Feb 19 13:05:47 2021 +0100 arm: Fix ICE with -fstack-protector -mpure-code [PR98998] The vla15.C testcase ICEs with -mcpu=cortex-m1 -mpure-code -fstack-protector -mthumb as what force_const_mem returns (a SYMBOL_REF) is not a valid memory address. Previously the code was moving the address of the force_const_mem into a register rather than the content of that MEM, so that instruction must have been supported and loading from a MEM with a single REG base ought to be valid too. 2021-02-19 Jakub Jelinek <ja...@redhat.com> PR target/98998 * config/arm/arm.md (*stack_protect_combined_set_insn, *stack_protect_combined_test_insn): If force_const_mem result is not valid general operand, force its address into the destination register first. * gcc.target/arm/pure-code/pr98998.c: New test.
