Switch test over to using -verify instead of using grep. PR11552. llvm-svn: 146544 2011-12-14 10:16:13 +08:00			`// RUN: %clang_cc1 %s -Eonly -verify`
Avoid testing / ## * in the lexer. This will cause an unhelpful error message to be emitted from the lexer. This fixes macro_paste_c_block_comment.c llvm-svn: 38737 2006-07-19 14:32:35 +08:00
Allow -verify directives to be filtered by preprocessing. This is accomplished by making VerifyDiagnosticsConsumer a CommentHandler, which then only reads the -verify directives that are actually in live blocks of code. It also makes it simpler to handle -verify directives that appear in header files, though we still have to manually reparse some files depending on how they are generated. This requires some test changes. In particular, all PCH tests now have their -verify directives outside the "header" portion of the file, using the @line syntax added in r159978. Other tests have been modified mostly to make it clear what is being tested, and to prevent polluting the expected output with the directives themselves. Patch by Andy Gibbs! (with slight modifications) The new Frontend/verify-* tests exercise the functionality of this commit, as well as r159978, r159979, and r160053 (Andy's other -verify enhancements). llvm-svn: 160068 2012-07-12 03:58:23 +08:00			`// expected-error@9 {{EOF}}`

Fix issue where a token paste which forms a /* or // would discard the rest of the input: token-pasting was producing a tok::eof. Patch by Andy Gibbs! llvm-svn: 158412 2012-06-14 03:02:56 +08:00			`// Demonstrate that an invalid preprocessing token`
