Stat system dependencies when using -verify-pch We don't stat the system headers to check for stalenes during regular PCH loading for performance reasons. When explicitly saying -verify-pch, we want to check all the dependencies - user or system. llvm-svn: 200979

// Setup:
// RUN: rm -rf %t
// RUN: mkdir -p %t/usr/include
// RUN: echo '// empty' > %t/usr/include/sys_header.h
Add a CC1 option -verify-pch This option will: - load the given pch file - verify it is not out of date by stat'ing dependencies, and - return 0 on success and non-zero on error llvm-svn: 200884

test: Disable standard system includes in %clang_cc1 This adds -nostdsysteminc to the %clang_cc1 expansion, which should make it harder to accidentally write tests that depend on headers in /usr/include. It also updates a few tests that use -isysroot <x> and a darwin triple to omit the triple and use -isystem <x>/usr/include instead, making them a little bit more general. Incidentally, this fixes a test failure I'm seeing on darwin in Modules/stddef.c, that happens because my system finds a stddef.h in /usr/include. llvm-svn: 219030

Fix test from r200979 on Windows Hopefully the last tweak needed to get this test working everywhere. Remove matching of the prefix of sys_header.h, which was never the point of the test anyway. This avoids dealing with path separators. llvm-svn: 200987
