* Using an invalid -O falls back on -O3 instead of an errorSylvestre Ledru2013-11-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Currently with clang: $ clang -O20 foo.c error: invalid value '20' in '-O20' With the patch: $ clang -O20 foo.c warning: optimization level '-O20' is unsupported; using '-O3' instead. 1 warning generated.

* Move remaining %clang_cc1 tests out of test/DriverAlp Toker2013-11-163-0/+60
| | | | | | | | | | | | | | clang -cc1 skips the driver so it never made sense to include these with the Driver tests. Basic type tests and flag tests generally both go in Frontend. Now that the final -cc1 tests have been moved out of test/Driver, add a local substitution to enforce and detect future mistakes. These miscategorized tests were probably the source of confusion in r194817. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@194919 91177308-0d34-0410-b5e6-96231b3b80d8

* Move -mfpmath handling to -cc1 and implement it for x86.Rafael Espindola2013-08-211-0/+43
| | | | | | | | | | | | | | | | | | | | | | | The original idea was to implement it all on the driver, but to do that the driver needs to know the sse level and to do that it has to know the default features of a cpu. Benjamin Kramer pointed out that if one day we decide to implement support for ' __attribute__ ((__target__ ("arch=core2")))', then the frontend needs to keep its knowledge of default features of a cpu. To avoid duplicating which part of clang handles default cpu features, it is probably better to handle -mfpmath in the frontend. For ARM this patch is just a small improvement. Instead of a cpu list, we check if neon is enabled, which allows us to reject things like -mcpu=cortex-a9 -mfpu=vfp -mfpmath=neon For X86, since LLVM doesn't support an independent ssefp feature, we just make sure the selected -mfpmath matches the sse level. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@188939 91177308-0d34-0410-b5e6-96231b3b80d8

* Extended VerifyDiagnosticConsumer to also verify source file for diagnostic.Andy Gibbs2013-04-171-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* rewrite-includes: Rewrite __has_include(_next) to get rid of a host dependency.Benjamin Kramer2013-04-163-0/+41
| | | | | | | | | | | | | | 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.

* Change VerifyDiagnosticConsumer so that it *must* contain at least one ↵Andy Gibbs2012-10-193-5/+48
| | | | | | | | | | "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.

* Update VerifyDiagnosticConsumer to only get directives during parsing.Jordan Rose2012-08-103-0/+39
| | | | | | | | | | | | | | | | | | | | 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
* Allow -verify directives to be filtered by preprocessing.Jordan Rose2012-07-113-0/+124
| | | | | | | | | | | | | | | | | | | | | 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!
