--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:a964f494cd5a90f631b8c0c01777a9899e0351ce commit r10-9467-ga964f494cd5a90f631b8c0c01777a9899e0351ce Author: Jakub Jelinek <ja...@redhat.com> Date: Wed Feb 10 19:52:37 2021 +0100 varasm: Fix ICE with -fsyntax-only [PR99035] My FE change from 2 years ago uses TREE_ASM_WRITTEN in -fsyntax-only mode more aggressively to avoid "expanding" functions multiple times. With -fsyntax-only nothing is really expanded, so I think it is acceptable to adjust the assert and allow declare_weak at any time, with -fsyntax-only we know it is during parsing only anyway. 2021-02-10 Jakub Jelinek <ja...@redhat.com> PR c++/99035 * varasm.c (declare_weak): For -fsyntax-only, allow even TREE_ASM_WRITTEN function decls. * g++.dg/ext/weak6.C: New test. (cherry picked from commit 0f39fb7b001df7cdba56cd5c572d0737667acd2c)
