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

2011-11-04Enable -flimit-debug-info by default. Now, clang lazily emits debug info for ↵Devang Patel

2011-11-04[driver] Don't blindly accept all -g options.Chad Rosier
rdar://10383444 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143732 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
2011-11-04Sink the handling of -fobjc-arc-cxxlib to live with the other -fobjc-arcChandler Carruth
implementation in the driver. This cleans up the signature and semantics of the include flag adding component of the toolchain. Another step to ready it for holding all the InitHeaderSearch logic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143686 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-04Add a FIXME to cleanup the CPATH handling. It's currently burried withChandler Carruth
the rest of the mess in InitHeaderSearch.cpp. We could hoist it into the driver profitably, removing more noise from the driver -> frontend communication. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143685 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-04Add a system include management interface to the toolchain, and call itChandler Carruth
and the C++ include management routine from the proper place when forming preprocessor options in the driver. This is the first step to teaching the driver to manage all of the header search paths. Currently, these methods remain just stubs in the abstract toolchain. Subsequent patches will flesh them out with implementations for various toolchains based on the current code in InitHeaderSearch.cpp. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143684 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-02Invoke the Darwin assembler with -g instead of --gdwarf2.Bob Wilson
The -g and --gdwarf2 options are currently synonyms to the Darwin assembler. But clang itself does not recognize --gdwarf2, so if we want to experiment with using clang, with its integrated assembler, to replace the default assembler, it is necessary to use -g. <rdar://problem/10349486> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143533 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-30Stop disabling integrated assembler with -static. <rdar://problem/10175391>Bob Wilson

2011-10-14Use Triple.isOSDarwin() instead of comparing against Triple::Darwin.Bob Wilson
There are now separate Triple::MacOSX and Triple::IOS values for the OS so comparing against Triple::Darwin will fail to match those. Note that I changed the expected output for the Driver/rewrite-objc.m test, which had previously not been passing Darwin-specific options with the macosx triple. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141944 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-11Driver: Add support for a new -nostdlibinc option.Daniel Dunbar
- This disables the system include directories, but not the compiler builtin directories. Useful for projects that want to use things like the intrinsic headers, but are otherwise freestanding. - I'm willing to reconsider the option naming, I also considered providing an explicit -builtinc (which would match -nobuiltininc), but this is more consistent with existing options. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141692 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-02Make -fobjc-nonfragile-abi the -cc1 default, since it's theJohn McCall
increasingly prevailing case to the point that new features like ARC don't even support the fragile ABI anymore. This required a little bit of reshuffling with exceptions because a check was assuming that ObjCNonFragileABI was only being set in ObjC mode, and that's actually a bit obnoxious to do. Most, though, it involved a perl script to translate a ton of test cases. Mostly no functionality change for driver users, although there are corner cases with disabling language-specific exceptions that we should handle more correctly now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140957 91177308-0d34-0410-b5e6-96231b3b80d8

specification flags to cc1. This fixes PR10369 (__builtin_NSStringMakeConstantString() selecting the wrong runtime in C / C++ code and crashing, although it doesn't fix the problem that instantiating the Mac runtime for non-Darwin targets was crashing.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140853 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-22Add support for CPATH and friends.Benjamin Kramer
This moves the existing code for CPATH into the driver and adds the environment lookup and path splitting there. The paths are then passed down to cc1 with -I options (CPATH), added after the normal user-specified include dirs. Language specific paths are passed via -LANG-isystem and the actual filtering is performed in the frontend. I tried to match GCC's behavior as close as possible Fixes PR8971. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140341 91177308-0d34-0410-b5e6-96231b3b80d8

compiler switch: -fms-compatility. Microsoft specific tweaking will now fall into 2 categories: - fms-extension: Microsoft specific extensions that should never change the meaning of an otherwise well formed code. Currently map to LangOptions::Microsoft. (To be clearer, I am planning to change the name to LangOptions::MicrosoftExt). - fms-compatibility: Really a MSVC emulation mode. Map to LangOptions::MicrosoftMode. Can change the meaning of an otherwise standard conformant program. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139978 91177308-0d34-0410-b5e6-96231b3b80d8
