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
