Fix PCH/preprocess test to be more useful, and unbreak -E mode with implicit PCH, which I broke. llvm-svn: 86921
2009-11-12 09:36:20 +08:00
// Check that -E mode is invariant when using an implicit PCH.
Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446

// RUN: %clang_cc1 -include %S/preprocess.h -E -o %t.orig %s
// RUN: %clang_cc1 -emit-pch -o %t %S/preprocess.h
// RUN: %clang_cc1 -include-pch %t -E -o %t.from_pch %s

Make precompiled headers work with -E. When we're only preprocessing (with -E), we turn the PCH include into an implicit include of the file from which the PCH file was generated. llvm-svn: 71534
