Fix crash on invalid if we can't find a suitable PCH file in a specified directory, and our frontend action cares whether the frontend setup actually succeeded. llvm-svn: 246881
2015-09-05 05:44:32 +08:00
// RUN: rm -rf %t.h.gch
If the precompiled header named by "-include" is actually a directory, check each of the files within that directory to determine if any of them is an AST file that matches the language and target options. If so, the first matching AST file is loaded. This fixes a longstanding discrepency with GCC's precompiled header implementation. llvm-svn: 166469

//
Teach the PCH validator to check the preprocessor options, especially the macros that are #define'd or #undef'd on the command line. This checking happens much earlier than the current macro-definition checking and is far cleaner, because it does a direct comparison rather than a diff of the predefines buffers. Moreover, it allows us to use the result of this check to skip over PCH files within a directory that have non-matching -D's or -U's on the command line. Finally, it improves the diagnostics a bit for mismatches, fixing <rdar://problem/8612222>. The old predefines-buffer diff'ing will go away in a subsequent commit. llvm-svn: 166641

Explicitly specify C++98 when building the C++ precompiled header for this test, so that the test will work on Windows. llvm-svn: 166601

Fix FileCheck --check-prefix lines. Various tests had sprung up over the years which had --check-prefix=ABC on the RUN line, but "CHECK-ABC:" later on. This happened to work before, but was strictly incorrect. FileCheck is getting stricter soon though. Patch by Ron Ofir. llvm-svn: 188174
