2013-04-17Extended VerifyDiagnosticConsumer to also verify source file for diagnostic.Andy Gibbs
VerifyDiagnosticConsumer previously would not check that the diagnostic and its matching directive referenced the same source file. Common practice was to create directives that referenced other files but only by line number, and this led to problems such as when the file containing the directive didn't have enough lines to match the location of the diagnostic in the other file, leading to bizarre file formatting and other oddities. This patch causes VerifyDiagnosticConsumer to match source files as well as line numbers. Therefore, a new syntax is made available for directives, for example: // expected-error@file:line {{diagnostic message}} This extends the @line feature where "file" is the file where the diagnostic is generated. The @line syntax is still available and uses the current file for the diagnostic. "file" can be specified either as a relative or absolute path - although the latter has less usefulness, I think! The #include search paths will be used to locate the file and if it is not found an error will be generated. The new check is not optional: if the directive is in a different file to the diagnostic, the file must be specified. Therefore, a number of test-cases have been updated with regard to this. This closes out PR15613. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179677 91177308-0d34-0410-b5e6-96231b3b80d8

When support was added for declaration arguments, the case of variadic declaration arguments was not supported. This patch fixes that problem by not crashing when certain ValueDecl's are null.

2013-03-15Improve template diffing handling of default integer values.Richard Trieu
When the template argument is both default and value dependent, the expression retrieved for the default argument cannot be evaluated, thus never matching any argument value.

Also, output the original expression to provide more information about the argument mismatch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177209 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-30Diagnostics: if a line is longer than 4096 characters, don't print it.Jordan Rose
Specifically, don't print snippets, caret diagnostics, or ranges for lines over 4096 characters. We copy the line around a few times in our diagnostics machinery, and we have to print a caret line that's just as long. This uses a lot of memory just to create a poor user experience as we print out a line much too long for anyone to read...or spend extra energy trying to fit it to -fmessage-length. <rdar://problem/13106850> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173976 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-17Suppress all -Wunused-value warnings from macro body expansions.Matt Beaumont-Gay
This is inspired by a number of false positives in real code, including PR14968. I've added test cases reduced from these false positives to test/Sema/unused-expr.c, as well as corresponding test cases that pass the offending expressions as arguments to a no-op macro to ensure that we do warn there. This also removes my previous tweak from r166522/r166534, so that we warn on unused cast expressions in macro arguments. There were several test cases that were using -Wunused-value to test general diagnostic emission features; I changed those to use other warnings or warn on a macro argument expression. I stared at the test case for PR14399 for a while with Richard Smith and we believe the new test case exercises the same codepaths as before. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172696 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-13More hacking on mapDiagnosticRanges to make it handle more cases.Eli Friedman
This still isn't quite right, but it fixes a crash. I factored out findCommonParent because we need it on the result of getImmediateExpansionRange: for a function macro, the beginning and end of an expansion range can come out of different macros/macro arguments, which means the resulting range is a complete mess to handle consistently. I also made some changes to how findCommonParent works; it works somewhat better in some cases, and somewhat worse in others, but I think overall it's a better balance. I'm coming to the conclusion that mapDiagnosticRanges isn't using the right algorithm, though: chasing the caret is fundamentally more complicated than any algorithm which only considers one FileID for the caret can handle because each SourceLocation doesn't really have a single parent. We need to follow the same path of choosing expansion locations and spelling locations which the caret used to come up with the correct range in the general case.
