There are some problems here, this should fix one of them: the getFilename function returns "<stdin>" for spelling locations, because the input to clang is sort of preprocessed via -frewrite-includes if icecream is used and the file is built on a remote host (whereas it's apparently not preprocessed if the file is compiled locally by icecream). Using getPresumedLoc() uses the #line directives in the preprocessed input, which avoids the problem but is more expensive, so try to use it only when necessary. The getFileEntry(getMainFileID())->getName() pattern will also result in "<stdin>", but fortunately icecream passes -main-file-name, which oddly enough isn't used by the SourceManager's spelling locations, but is available separately via CodeGenOptions. This builds everything successfully with clang version 6.0.0: ICECC_PREFERRED_HOST=myremote make check gb_SUPPRESS_TESTS=t Change-Id: Ic121511683e5302d7b9d85186c8b9c4a5443fa1b Reviewed-on: https://gerrit.libreoffice.org/54993 Tested-by: Jenkins Reviewed-by: Thorsten Behrens <Thorsten.Behrens@CIB.de>
