--- 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:801fb71f83624f0bf6d6bd27121d4a332103f7be commit r15-7414-g801fb71f83624f0bf6d6bd27121d4a332103f7be Author: Jakub Jelinek <ja...@redhat.com> Date: Fri Feb 7 14:28:57 2025 +0100 c++: Use cplus_decl_attributes rather than decl_attributes in grokdecl [PR118773] My r15-3046 change regressed the first half of the following testcase. When it calls decl_attributes, it doesn't handle attributes with dependent arguments correctly and so is now rejected that N is not a constant integer during template parsing. I've actually followed the pointer/reference case which did that too and that one has been failing for a couple of years on the second part of the testcase. Note, there is also if (decl_context != PARM && decl_context != TYPENAME) /* Assume that any attributes that get applied late to templates will DTRT when applied to the declaration as a whole. */ late_attrs = splice_template_attributes (&attrs, type); returned_attrs = decl_attributes (&type, attr_chainon (returned_attrs, attrs), attr_flags); returned_attrs = attr_chainon (late_attrs, returned_attrs); call directly to decl_attributes in grokdeclarator, but this one handles the splicing manually, so maybe it is ok as is (and I don't have a testcase of anything misbehaving for that). 2025-02-07 Jakub Jelinek <ja...@redhat.com> PR c++/118773 * decl.cc (grokdeclarator): Use cplus_decl_attributes rather than decl_attributes for std_attributes on pointer and array types. * g++.dg/cpp0x/gen-attrs-87.C: New test. * g++.dg/gomp/attrs-3.C: Adjust expected diagnostics.
