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

2011-11-14Don't track depfiles as result files which need to be cleaned up on failure.Matt Beaumont-Gay
This is a partial revert of r143846. While cleaning up after a crash is probably a good idea, we were also deleting .d files if the compilation failed due to invalid input, which is not the desired behavior. The test is XFAIL'd until the cleanup code can be reworked to do the right thing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144590 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-05Move the Linux header searching from the Frontend to the Driver. This isChandler Carruth
the first (and diff-noisiest) step to making Linux header searching tremendously more principled and less brittle. Note that this step should have essentially no functional impact. We still search the exact same set of paths in the exact same order. The only change here is where the code implementing such a search lives. This has one obvious negative impact -- we now pass a ludicrous number of flags to the CC1 layer. That should go away as I re-base this logic on the logic to detect a GCC installation. I want to do this in two phases so the bots can tell me if this step alone breaks something, and so that the diffs of the refactoring make more sense. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143822 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-04Sink the strange '-stdlib=...' flag handling into the C++ includeChandler Carruth
handling logic of the generic ToolChain. This flag, despite its name, has *nothing* to do with the GCC flag '-nostdlib' that relates (exclusively) to the linking behavior. It is a most unfortunate name in that regard... It is used to tell InitHeaderSearch.cpp *which* set of C++ standard library header search paths to use -- those for libstdc++ from GCC's installation, or those from a libc++ installation. As this logic is hoisted out of the Frontend, and into the Driver as part of this ToolChain, the generic method will be overridden for the platform, where it can implement this logic directly. As such, hiding the CC1 option passing in the generic space is a natural fit despite the odd naming. Also, expand on the comments to clarify whats going on, and tidy up the Tools.cpp code now that its simpler. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143687 91177308-0d34-0410-b5e6-96231b3b80d8
