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

2011-12-17Split the Windows toolchain definition into its own file. This isChandler Carruth
especially nice as the Windows toolchain needs the windows header files, and has lots of platform specific hooks in it. To facilitate the split, hoist a bunch of file-level static helpers into class-level static helpers. Spiff up their doxygen comments while there as they're now more likely to be looked up via docs. Hopefully, this will be followed by further breaking apart of the toolchain definitions. Most of the large and complex ones should likely live on their own.
