2011-02-28Make -fobjc-nonfragile-abi and -fgnu-runtime imply -fblocks (unless ↵David Chisnall
-fno-blocks is specified), because this combination of flags defines an Objective-C runtime that includes a blocks runtime. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126654 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-28Fix a tiny goof in the Driver's logic which caused the explicit presenceChandler Carruth
of -fexceptions to disably C++ exceptions. The correct code was in the ObjC branch, this just mirrors that logic on the C++ side of things. Thanks to John Wiegley for pointing this out. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126640 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-28Add a -fcxx-exceptions flag to the frontend, which can be used to enableAnders Carlsson
C++ exceptions, even when exceptions have been turned off using -fno-exceptions. Make the -fobjc-exceptions flag do the same thing, but for Objective-C exceptions. C++ and Objective-C exceptions can also be disabled using -fno-cxx-excptions and -fno-objc-exceptions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126630 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-14[analyzer] Overhauling of the checker registration mechanism.Argyrios Kyrtzidis
-Checkers will be defined in the tablegen file 'Checkers.td'. -Apart from checkers, we can define checker "packages" that will contain a collection of checkers. -Checkers can be enabled with -analyzer-checker=<name> and disabled with -analyzer-disable-checker=<name> e.g: Enable checkers from 'cocoa' and 'corefoundation' packages except the self-initialization checker: -analyzer-checker=cocoa -analyzer-checker=corefoundation -analyzer-disable-checker=cocoa.SelfInit -Introduces CheckerManager and CheckerProvider. CheckerProviders get the set of checker names to enable/disable and register them with the CheckerManager which will be the entry point for all checker-related functionality. Currently only the self-initialization checker takes advantage of the new mechanism. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125503 91177308-0d34-0410-b5e6-96231b3b80d8

to allow us to explicitly control whether or not Objective-C properties are default synthesized.
