2009-05-08initial support for ObjC exceptions with the GNU runtime:Chris Lattner
"This patch is a first pass at adding support for exceptions for the GNU runtime. There are a few limitations at present: - @synchronized() is not yet supported at all. gcc currently emits calls to runtime library functions that don't exist for this directive. - Only id @catch statements are currently working. This is enough for NS_DURING and friends, but I need to spend more time reading the output from gcc -S to work out how it finds the class pointer to make arbitrary class type catch statements work. - I've tested it with a few common cases[1] and the clang test suite (which doesn't test exceptions for the GNU runtime, but shows I haven't broken anything else), but there are probably a lot of cases I've missed."

2009-05-06Refactor BugReporter interface to have a new 'BugReporterContext' andTed Kremenek
'BugReporterVisitor'. This simplifies callbacks from BugReporter to BugReports (via VisitNode). It also lays the foundation for arbitrary visitor "call backs" that can be registered to a BugReporterContext as a PathDiagnostic is constructed. These call backs can help operate as separate "experts" that can work on constructed pieces of a PathDiagnostic for which they possess special knowledge. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71121 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-06More x86 target feature support.Daniel Dunbar
- Apologies for the extremely gross code duplication, I want to get this working and then decide how to get this information out of the back end. - This replaces -m[no-]sse4[12] by -m[no-]sse4, it appears gcc doesn't distinguish them? - -msse, etc. now properly disable/enable related features. - Don't always define __SSE3__... - The main missing functionality bit here is that we don't initialize the features based on the CPU for all -march options. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71117 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-06Improve handling of (X86) target features.Daniel Dunbar
- This is a WIP... - This adds -march= handling to the driver, and fixes the defaulting of -mcpu on Darwin (which was using the wrong test). Instead of handling -m{sse, ...} in the driver, pass them to clang-cc as -target-feature [+-]name In clang-cc, communicate with the (clang) target to discover the legal features of a target, and the features which are enabled based on -mcpu. This is currently hardcoded just enough to not be a feature regression, we need to get this information from the backend's TableGen information somehow. This is used to construct the full list of features which are being used, which is in turn used to initialize the predefines. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@71061 91177308-0d34-0410-b5e6-96231b3b80d8
