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. Given these input files: :::::::::::::: mydir/myinc.h :::::::::::::: char* mystringh_file = __FILE__; char* mystringh_filename = __FILE_NAME__; char* mystringh_base_file = __BASE_FILE__; :::::::::::::: mydir/mysrc.c :::::::::::::: char* mystring_file = __FILE__; char* mystring_filename = __FILE_NAME__; char* mystring_base_file = __BASE_FILE__; we produce: $ gcc mydir/mysrc.c -I . -E char* mystringh_file = "./mydir/myinc.h"; char* mystringh_filename = "myinc.h"; char* mystringh_base_file = "mydir/mysrc.c"; char* mystring_file = "mydir/mysrc.c"; char* mystring_filename = "mysrc.c"; char* mystring_base_file = "mydir/mysrc.c"; 2021-05-20 Christophe Lyon <christophe.lyon@linaro.org> Torbjörn Svensson <torbjorn.svensson@st.com> PR c/42579 libcpp/ * include/cpplib.h (cpp_builtin_type): Add BT_FILE_NAME entry. * init.c (builtin_array): Likewise. * macro.c (_cpp_builtin_macro_text): Add support for BT_FILE_NAME. gcc/ * doc/cpp.texi (Common Predefined Macros): Document __FILE_NAME__. gcc/testsuite/ * c-c++-common/spellcheck-reserved.c: Add tests for __FILE_NAME__. * c-c++-common/cpp/file-name-1.c: New test. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
