* [Driver] Refactor clang driver to use LLVM's Option libraryReid Kleckner2013-06-142-44/+67
| | | | | | | | | | | | | | | | | | The big changes are: - Deleting Driver/(Arg|Opt)* - Rewriting includes to llvm/Option/ and re-sorting - 'using namespace llvm::opt' in clang::driver - Fixing the autoconf build by adding option everywhere As discussed in the review, this change includes using directives in header files. I'll make follow up changes to remove those in favor of name specifiers. Reviewers: espindola Differential Revision: http://llvm-reviews.chandlerc.com/D975 llvm-svn: 183989

| | | | | | | | | | | A while ago we allowed libclang to build a PCH that had compiler errors; this was to retain the performance afforded by a PCH even if the user's code is in an intermediate state. Extend this for the precompiled preamble as well. rdar://14109828 llvm-svn: 183717

* Remove DiagnosticConsumer::clone(), a bad idea that is now unused.Douglas Gregor2013-05-037-47/+5
| | | | llvm-svn: 181070
* When building a module, forward diagnostics to the outer diagnostic consumer.Douglas Gregor2013-05-034-10/+44
| | | | | | | | | | | | | | | Previously, we would clone the current diagnostic consumer to produce a new diagnostic consumer to use when building a module. The problem here is that we end up losing diagnostics for important diagnostic consumers, such as serialized diagnostics (where we'd end up with two diagnostic consumers writing the same output file). With forwarding, the diagnostics from all of the different modules being built get forwarded to the one serialized-diagnostic consumer and are emitted in a sane way. Fixes <rdar://problem/13663996>. llvm-svn: 181067

* [driver] Improve the implementation of the -Ofast option.Chad Rosier2013-04-241-11/+2
| | | | | | | | | | | | Specifically, allow the flags that fall under this umbrella (i.e., -O3, -ffast-math, and -fstrict-aliasing) to be overridden/disabled with the individual -O[0|1|2|s|z]/-fno- flags. This also fixes the handling of various floating point optimization flags that are modified by -ffast-math (and thus -Ofast as well). Part of rdar://13622687 llvm-svn: 180204

* Dropped the parentheses for #pragma message and its kin in the -E output ↵Andy Gibbs2013-04-181-5/+3

* Fix off-by-one error in #pragma clang system_header.Jordan Rose2013-04-171-5/+6
| | | | | | | | | | | The system_header pragma (from GCC) is implemented using line notes in the source manager. However, a line note's line number specifies the number not for the current line, but for the next line. This was making all line numbers appear off by one after the pragma. Reported by Andy Gibbs, uncovered during r179677. llvm-svn: 179709
* Implemented #pragma GCC warning/error in the same mould as #pragma message.Andy Gibbs2013-04-171-4/+18

* Extended VerifyDiagnosticConsumer to also verify source file for diagnostic.Andy Gibbs2013-04-171-12/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 179677

* [Modules] Convert module specific -fno-modules-autolink into -fno-autolink.Daniel Dunbar2013-04-161-1/+1
| | | | | | | | | - There is no reason to have a modules specific flag for disabling autolinking. Instead, convert the existing flag into -fno-autolink (which should cover other autolinking code generation paths like #pragmas if and when we support them). llvm-svn: 179612

| | | | | | | | | This is a Darwin-SDK-specific hash criteria used to identify a particular SDK without having to hash the contents of all of its headers. If other platforms have such versioned files, we should add those checks here. llvm-svn: 179346
