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
2013-04-16rewrite-includes: Rewrite __has_include(_next) to get rid of a host dependency.Benjamin Kramer
This broke e.g. compiling a crash report from a glibc system on Darwin. Sadly, the implementation had to game the lexer a lot as we're not using a real preprocessor here. It also doesn't handle special cases like arbitrary macros in __has_include, but since this macro isn't common outside of clang's headers we can get away with that. Fixes PR14422.

2012-10-24A number of test cases assume that an "int" parameter or return valueUlrich Weigand
will be represented in the IR as a plain "i32" type. This causes the tests to spuriously fail on platforms where int is not a 32-bit type, or where the ABI requires attributes like "signext" or "zeroext" to be used. This patch adds -triple or -target parameters to force those tests to use the i386-unknown-unknown target. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166551 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-19Change VerifyDiagnosticConsumer so that it *must* contain at least one ↵Andy Gibbs
"expected-*" directive. As a result, for test-cases that are not expected to generate any diagnostics, an additional directive "expected-no-diagnostics" has been implemented which can then be included in such test-cases. This new directive may not be used in conjunction with any other "expected-*" directive. This change was initially proposed as a solution to the problem highlighted by check-in r164677, i.e. that -verify will not cause a test-case failure where the compile command does not actually reference the file.

2012-08-10Update VerifyDiagnosticConsumer to only get directives during parsing.Jordan Rose
The old behavior was to re-scan any files (like modules) where we may have directives but won't actually be parsing during the -verify invocation. Now, we keep the old behavior in Debug builds as a sanity check (though modules are a known entity), and expect all legitimate directives to come from comments seen by the preprocessor. This also affects the ARC migration tool, which captures diagnostics in order to filter some out. This change adds an explicit cleanup to CaptureDiagnosticsConsumer in order to let its sub-consumer handle the real end of diagnostics. This was originally split into four patches, but the tests do not run cleanly without all four, so I've combined them into one commit. Patches by Andy Gibbs, with slight modifications from me. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161650 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-11Allow -verify directives to be filtered by preprocessing.Jordan Rose
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!

2012-02-15Remove the unuseful -fdiagnostics-show-nameDavid Blaikie
This option was added in r129614 and doesn't have any use case that I'm aware of. It's possible that external tools are using these names - and if that's the case we can certainly reassess the functionality, but for now it lets us shave out a few unneeded bits from clang. Move the "StaticDiagNameIndex" table into the only remaining consumer, diagtool. This removes the actual diagnostic name strings from clang entirely.
