--- Comment #2 from GCC 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:0b58219fe112c01ff335edf699c4fc69e718c75b commit r15-7069-g0b58219fe112c01ff335edf699c4fc69e718c75b Author: Jakub Jelinek <ja...@redhat.com> Date: Mon Jan 20 18:00:43 2025 +0100 c++: Handle RAW_DATA_CST in make_tree_vector_from_ctor [PR118528] This is the first bug discovered today with the https://gcc.gnu.org/pipermail/gcc-patches/2025-January/673945.html hack but then turned into proper testcases where embed-21.C FAILed since introduction of optimized #embed support and the other when optimizing large C++ initializers using RAW_DATA_CST. The problem is that the C++ FE calls make_tree_vector_from_ctor and uses that as arguments vector for deduction guide handling. The call.cc code isn't prepared to handle RAW_DATA_CST just about everywhere, so I think it is safer to make sure RAW_DATA_CST only appears in CONSTRUCTOR_ELTS and nowhere else. Thus, the following patch expands the RAW_DATA_CSTs from initializers into multiple INTEGER_CSTs in the returned vector. 2025-01-20 Jakub Jelinek <ja...@redhat.com> PR c++/118528 * c-common.cc (make_tree_vector_from_ctor): Expand RAW_DATA_CST elements from the CONSTRUCTOR to individual INTEGER_CSTs. * g++.dg/cpp/embed-21.C: New test. * g++.dg/cpp2a/class-deduction-aggr16.C: New test.
