2012-03-06Add new code migrator support for migrating existing Objective-C code to useTed Kremenek
the new Objective-C NSArray/NSDictionary/NSNumber literal syntax. This introduces a new library, libEdit, which provides a new way to support migration of code that improves on the original ARC migrator. We now believe that most of its functionality can be refactored into the existing libraries, and thus this new library may shortly disappear. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152141 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-06Add clang support for new Objective-C literal syntax for NSDictionary, NSArray,Ted Kremenek
NSNumber, and boolean literals. This includes both Sema and Codegen support. Included is also support for new Objective-C container subscripting. My apologies for the large patch. It was very difficult to break apart. The patch introduces changes to the driver as well to cause clang to link in additional runtime support when needed to support the new language features. Docs are forthcoming to document the implementation and behavior of these features. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152137 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-01Add a flag -fthread-sanitizer.Kostya Serebryany
This flag enables ThreadSanitizer instrumentation committed to llvm as r150423. The patch includes one test for -fthread-sanitizer and one similar test for -faddress-sanitizer. This patch does not modify the linker flags (as we do it for -faddress-sanitizer) because the run-time library is not yet committed and it's structure in compiler-rt is not 100% clear. The users manual wil be changed in a separate commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151846 91177308-0d34-0410-b5e6-96231b3b80d8

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.

2012-01-25Delete the driver's HostInfo class. This abstraction just never reallyChandler Carruth
did anything. The two big pieces of functionality it tried to provide was to cache the ToolChain objects for each target, and to figure out the exact target based on the flag set coming in to an invocation. However, it had a lot of flaws even with those goals: - Neither of these have anything to do with the host, or its info. - The HostInfo class was setup as a full blown class *hierarchy* with a separate implementation for each "host" OS. This required dispatching just to create the objects in the first place. - The hierarchy claimed to represent the host, when in fact it was based on the target OS. - Each leaf in the hierarchy was responsible for implementing the flag processing and caching, resulting in a *lot* of copy-paste code and quite a few bugs. - The caching was consistently done based on architecture alone, even though *any* aspect of the targeted triple might change the behavior of the configured toolchain. - Flag processing was already being done in the Driver proper, separating the flag handling even more than it already is. Instead of this, we can simply have the dispatch logic in the Driver which previously created a HostInfo object create the ToolChain objects. Adding caching in the Driver layer is a tiny amount of code. Finally, pulling the flag processing into the Driver puts it where it belongs and consolidates it in one location. The result is that two functions, and maybe 100 lines of new code replace over 10 classes and 800 lines of code. Woot. This also paves the way to introduce more detailed ToolChain objects for various OSes without threading through a new HostInfo type as well, and the accompanying boiler plate. That, of course, was the yak I started to shave that began this entire refactoring escapade. Wheee! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148950 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-13remove assertions in the Hexagon backend specific clang driverSebastian Pop
Patch from Jyotsna Verma: I have made the changes to remove assertions in the Hexagon backend specific clang driver. Instead of asserting on invalid arch name, it has been modified to use the default value. I have changed the implementation of the CPU flag validation for the Hexagon backend. Earlier, the clang driver performed the check and asserted on invalid inputs. In the new implementation, the driver passes the last CPU flag (or sets to "v4" if not specified) to the compiler (and also to the assembler and linker which perform their own check) instead of asserting on incorrect values. This patch changes the setCPU function for the Hexagon backend in clang/lib/Basic/Targets.cpp which causes the compiler to error out on incorrect CPU flag values. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148139 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-02Fix PR11685 by implementing -ffast-math and its various friends in theChandler Carruth
Clang driver. This involves a bunch of silly option parsing code to try to carefully emulate GCC's options. Currently, this takes a conservative approach, and unless all of the unsafe optimizations are enabled, none of them are. The fine grained control doesn't seem particularly useful. If it ever becomes useful, we can add that to LLVM first, and then expose it here. This also fixes a few tiny bugs in the flag management around -fhonor-infinities and -fhonor-nans; the flags now form proper sets both for enabling and disabling, with the last flag winning. I've also implemented a moderately terrifying GCC feature where a language change is also provided by the '-ffast-math' flag by defining the __FAST_MATH__ preprocessor macro. This feature is tracked and serialized in the frontend but it isn't used yet. A subsequent patch will add the preprocessor macro and tests for it. I've manually tested that codegen appears to respect this, but I've not dug in enough to see if there is an easy way to test codegen options w/o relying on the particulars of LLVM's optimizations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147434 91177308-0d34-0410-b5e6-96231b3b80d8
