* Eliminate the uglified keyword __import_module__ for importingDouglas Gregor2012-01-0328-100/+122
| | | | | | | | | | | | | modules. This leaves us without an explicit syntax for importing modules in C/C++, because such a syntax needs to be discussed first. In Objective-C/Objective-C++, the @import syntax is used to import modules. Note that, under -fmodules, C/C++ programs can import modules via the #include mechanism when a module map is in place for that header. This allows us to work with modules in C/C++ without committing to a syntax. llvm-svn: 147467

* Fix PR11685 by implementing -ffast-math and its various friends in theChandler Carruth2012-01-028-23/+255
| | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 147434

However, note that we're not taking advantage of much of this code yet, because we're still re-using ObjCProtocolDecls. llvm-svn: 147410
