--- Comment #2 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:0b7a11874d4eb428c18a91f38786032ce0e77a96 commit r12-2313-g0b7a11874d4eb428c18a91f38786032ce0e77a96 Author: Jason Merrill <ja...@redhat.com> Date: Wed Jul 14 17:10:49 2021 -0400 c++: fix tree_contains_struct for C++ types [PR101095] Many of the types from cp-tree.def were only marked as having tree_common, when actually most of them have type_non_common. This broke g++.dg/modules/xtreme-header-2, as the modules code relies on tree_contains_struct to know what bits it needs to stream. We don't seem to use type_non_common for TYPE_ARGUMENT_PACK, so I bumped it down to TS_TYPE_COMMON. I tried doing the same in cp_tree_size, but that breaks without more extensive changes to tree_node_structure. Why do we need the init_ts function anyway? It seems redundant with tree_node_structure. PR c++/101095 gcc/cp/ChangeLog: * cp-objcp-common.c (cp_common_init_ts): Mark types as types. (cp_tree_size): Remove redundant entries.
