--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Stefan Schulze Frielinghaus <stefa...@gcc.gnu.org>: https://gcc.gnu.org/g:4cff794ca18a96ceeb83ccb18b08ffa0a63c58af commit r16-3853-g4cff794ca18a96ceeb83ccb18b08ffa0a63c58af Author: Stefan Schulze Frielinghaus <stefa...@gcc.gnu.org> Date: Mon Sep 15 09:10:53 2025 +0200 Bail out early during gimplify_asm_expr [PR121391] In case an asm operand is an error node, constraints etc. are still validated. Furthermore, all other operands are gimplified, although an error is returned in the end anyway. For hard register constraints an operand is required in order to determine the mode from which the number of registers follows. Therefore, instead of adding extra guards, bail out early. gcc/ChangeLog: PR middle-end/121391 * gimplify.cc (gimplify_asm_expr): In case an asm operand is an error node, bail out early. gcc/testsuite/ChangeLog: * gcc.dg/pr121391-1.c: New test. * gcc.dg/pr121391-2.c: New test.
