Use the -E option when invoking clang. Only the preprocessor is required to perform this test. llvm-svn: 48636 2008-03-21 15:02:04 +08:00			`/* RUN: clang -E %s 2>&1 >/dev/null \| grep error: \| count 3`
If we see an invalid #ifdef directive, enter a conditional compilation region so that we don't emit an error on the #endif. Suggestion by Neil. llvm-svn: 42258 2007-09-24 13:14:57 +08:00			`*/`

Fix PR1936, a crash on malformed #if. Thanks to Neil for noticing this! llvm-svn: 46256 2008-01-23 03:34:51 +08:00			`/* End of function-like macro invocation in #ifdef */`
