Oh, well, gcc implementation is rather generic, it relies on gcc's config.gcc to detect glibc and then it adds a hook that unconditionally provides stdc-predef.h (TARGET_C_PREINCLUDE). Currently config.gcc does that for the following pattern of triples: *-*-linux* | frv-*-*linux* | *-*-kfreebsd*-gnu | *-*-knetbsd*-gnu | *-*-gnu* | *-*-kopensolaris*-gnu) I'm not sure how far into that do you really want to dive.... :-/ https://reviews.llvm.org/D34158 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
