Hello and Happy New Year, as https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79106 is still open, I wanted to again bump this patch I provided a while back. It was earmarked for gcc-11 in https://gcc.gnu.org/pipermail/gcc-patches/2020-January/539201.html but did not make it into the release.
Original submission: https://gcc.gnu.org/legacy-ml/gcc-patches/2019-12/msg01113.html Please let me know if something is missing.

When GCC produces advanced diagnostics (with -fdiagnostics-show-caret), e.g. prints out the affected source line and fixit hints, it attempts to read the source file again, even when compiling a preprocessed file (-fpreprocessed). This leads to wrong diagnostics when building with a compile cluster, or, more generally, when changing or deleting the original source file. This patch attempts to alter the behavior by implementing a location_get_source_line_preprocessed function that can be used in diagnostic-show-locus.c in case a preprocessed file is compiled. There was some previous discussion on this behavior on PR preprocessor/79106. This is my first patch to GCC, so in case something is wrong with the format, please let me know. Best regards Lucas
