--- Comment #4 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:22aede7a1228617661105048a91fddd8797e141b commit r11-8108-g22aede7a1228617661105048a91fddd8797e141b Author: Jakub Jelinek <ja...@redhat.com> Date: Sat Apr 10 12:49:01 2021 +0200 expand: Fix up LTO ICE with COMPOUND_LITERAL_EXPR [PR99849] The gimplifier optimizes away COMPOUND_LITERAL_EXPRs, but they can remain in the form of ADDR_EXPR of COMPOUND_LITERAL_EXPRs in static initializers. By the TREE_STATIC check I meant to check that the underlying decl of the compound literal is a global rather than automatic variable which obviously can't be referenced in static initializers, but unfortunately with LTO it might end up in another partition and thus be DECL_EXTERNAL instead. 2021-04-10 Jakub Jelinek <ja...@redhat.com> PR lto/99849 * expr.c (expand_expr_addr_expr_1): Test is_global_var rather than just TREE_STATIC on COMPOUND_LITERAL_EXPR_DECLs. * gcc.dg/lto/pr99849_0.c: New test.
