This test was assuming that /usr/include was in the system header search path. That assumption should never have been true, but it was until I fixed it. Now that its fixed, add a triple here to get correct behavior even on Windows. llvm-svn: 143863 2011-11-06 14:59:15 +08:00			`// RUN: -isysroot %S/libroot %S/libroot/usr/include/reloc.h`

lib/Frontend/InitHeaderSearch.cpp: Tweak AddPath() to accept "/foo/bar" (not "X:\foo\bar") with -isysroot. test/PCH/reloc.c can pass. FIXME: We should consider better isysroot scheme on Win32 hosts. llvm-svn: 130683 2011-05-02 12:50:10 +08:00
Introduce the notion of "Relocatable" precompiled headers, which are built with a particular system root directory and can be used with a different system root directory when the headers it depends on have been installed. Relocatable precompiled headers rewrite the file names of the headers used when generating the PCH file into the corresponding file names of the headers available when using the PCH file.

Use %S, not `pwd`, and enable a line that does work. - Doug, please check. llvm-svn: 77778 2009-08-01 13:57:38 +08:00			`// expected-note{{previous definition}}`
