--- Comment #19 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:bd0485f20f4794f9787237706a6308473a8e9415 commit r13-4565-gbd0485f20f4794f9787237706a6308473a8e9415 Author: Jason Merrill <ja...@redhat.com> Date: Tue Dec 6 18:10:48 2022 -0500 c++: build initializer_list<string> in a loop [PR105838] The previous patch avoided building an initializer_list<string> at all when building a vector<string>, but in situations where that isn't possible, we could still build the initializer_list with a loop over a constant array. This is represented using a VEC_INIT_EXPR, which required adjusting a couple of places that expected the initializer array to have the same type as the target array and fixing build_vec_init not to undo our efforts. PR c++/105838 gcc/cp/ChangeLog: * call.cc (convert_like_internal) [ck_list]: Use maybe_init_list_as_array. * constexpr.cc (cxx_eval_vec_init_1): Init might have a different type. * tree.cc (build_vec_init_elt): Likewise. * init.cc (build_vec_init): Handle from_array from a TARGET_EXPR. Retain TARGET_EXPR of a different type. gcc/testsuite/ChangeLog: * g++.dg/tree-ssa/initlist-opt2.C: New test.
