--- 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:eb45d151fa1780d01533d9fc9545fec50bfd7152 commit r15-5189-geb45d151fa1780d01533d9fc9545fec50bfd7152 Author: Jakub Jelinek <ja...@redhat.com> Date: Wed Nov 13 09:41:41 2024 +0100 c: Implement C2Y N3298 - Introduce complex literals [PR117029] The following patch implements the C2Y N3298 paper Introduce complex literals by providing different (or no) diagnostics on imaginary constants (except for integer ones). For _DecimalN constants we don't support _Complex _DecimalN and error on any i/j suffixes mixed with DD/DL/DF, so nothing changed there. 2024-11-13 Jakub Jelinek <ja...@redhat.com> PR c/117029 libcpp/ * include/cpplib.h (struct cpp_options): Add imaginary_constants member. * init.cc (struct lang_flags): Add imaginary_constants bitfield.
