--- Comment #2 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Patrick Palka <ppa...@gcc.gnu.org>: https://gcc.gnu.org/g:843710c037c1396dcdbc23e5b6b456b8ae6e2b8b commit r11-2546-g843710c037c1396dcdbc23e5b6b456b8ae6e2b8b Author: Patrick Palka <ppa...@redhat.com> Date: Tue Aug 4 10:11:35 2020 -0400 c++: Member initializer list diagnostic locations [PR94024] This patch preserves the source locations of each node in a member initializer list so that during processing of the list we can set input_location appropriately for generally more accurate diagnostic locations. Since TREE_LIST nodes are tcc_exceptional, they can't have source locations, so we instead store the location in a dummy tcc_expression node within the TREE_TYPE of the list node. gcc/cp/ChangeLog: PR c++/94024 * init.c (sort_mem_initializers): Preserve TREE_TYPE of the member initializer list node. (emit_mem_initializers): Set input_location when performing each member initialization. * parser.c (cp_parser_mem_initializer): Attach the source location of this initializer to a dummy EMPTY_CLASS_EXPR within the TREE_TYPE of the list node. * pt.c (tsubst_initializer_list): Preserve TREE_TYPE of the member initializer list node. gcc/testsuite/ChangeLog: PR c++/94024 * g++.dg/diagnostic/mem-init1.C: New test.
