Reopening for further discussion or clarification. The changes appear to suggest that a PCH file won't be implicitly used when an explicit include for the corresponding header is made via the `-include` option, but that is not correct. $ cat t.h const int i = 0; $ cat t.c int g = i; $ clang t.h $ ls -1 t.c t.h t.h.gch $ clang -c -I. -include t.h t.c $ touch t.h $ clang -c -I. -include t.h t.c fatal error: file '/iusers/thonerma/tmp/pch/t.h' has been modified since the precompiled header 't.h.gch' was built: mtime changed note: please rebuild precompiled header 't.h.gch' 1 error generated. If the ability to include a PCH file via `-include` is intentional behavior (as I have always believed it to be), then I think the documentation should demonstrate both the `-include` and `-include-pch` methods of using a PCH file. Please note that gcc also supports implicit use of a PCH file via its -include option <https://gcc.gnu.org/onlinedocs/gcc/Precompiled-Headers.html>.
