--- Comment #9 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Christophe Lyon <cl...@gcc.gnu.org>: https://gcc.gnu.org/g:1a9b3f04c11eb467a8dc504a37dad57a371a0d4c commit r12-938-g1a9b3f04c11eb467a8dc504a37dad57a371a0d4c Author: Christophe Lyon <christophe.l...@linaro.org> Date: Thu May 20 08:10:50 2021 +0000 c: Add support for __FILE_NAME__ macro (PR c/42579) The toolchain provided by ST for stm32 has had support for __FILENAME__ for a while, but clang/llvm has recently implemented support for __FILE_NAME__, so it seems better to use the same macro name in GCC. It happens that the ST patch is similar to the one proposed in PR c/42579.
