2013-04-20Supports Sourcery CodeBench Mips toolchain directories tree.Simon Atanasyan
Sourcery CodeBench and modern FSF Mips toolchains require a bit more complicated algorithm to calculate headers, libraries and sysroot paths than implemented by Clang driver now. The main problem is that all these paths depend on a set of command line arguments additionally to a target triple value. For example, let $TC is a toolchain installation directory. If we compile big-endian 32-bit mips code, crtbegin.o is in the $TC/lib/gcc/mips-linux-gnu/4.7.2 folder and the toolchain's linker requires --sysroot=$TC/mips-linux-gnu/libc argument. If we compile little-endian 32-bit soft-float mips code, crtbegin.o is in the $TC/lib/gcc/mips-linux-gnu/4.7.2/soft-float/el folder and the toolchain's linker requires --sysroot=$TC/mips-linux-gnu/libc/soft-float/el argument. 1. Calculate MultiarchSuffix using all necessary command line options and use this MultiarchSuffix to detect crtbegin.o location in the GCCInstallationDetector::ScanLibDirForGCCTriple() routine. 2. If a user does not provide --sysroot argument to the driver explicitly, calculate new sysroot value based on command line options. Then use this calculated sysroot path: a. To populate a file search paths list in the Linux::Linux() constructor. b. To find Mips toolchain specific include headers directories in the Linux::AddClangSystemIncludeArgs() routine. c. To provide -–sysroot argument for a linker. Note: - The FSF's tree slightly differs (folder names) and is not supported yet. - New addExternCSystemIncludeIfExits() routine is a temporary solution. I plan to move path existence check to the addExternCSystemInclude() routine by a separate commit.

2013-03-20Remove the Tools DensMap from the toolchain.Rafael Espindola
Each toolchain has a set of tools, but they are all of known types. It can have a linker, an assembler, a "clang" (compile, analyze, ...) a non-clang compiler, etc. Instead of keeping a map, just have member variable for each type of tool. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177479 91177308-0d34-0410-b5e6-96231b3b80d8

svn 170909 added support for cortex-r5 but in this case it was done incorrectly.

2012-11-21Fix the '-fuse-init-array' option to actually be an option.Chandler Carruth
Previously, this flag to CC1 was never exposed at the clang driver layer, and if you happened to enable it (by being on Android or GCC 4.7 platform), you couldn't *disable* it, because there was no 'no' variant. The whole thing was confusingly implemented. Now, the target-specific flag processing gets the driver arg list, and we use standard hasFlag with a default based on the GCC version and/or Android platform. The user can still pass the 'no-' variant to forcibly disable the flag, or pass the positive variant to clang itself to enable the flag. The test has also been substantially cleaned up and extended to cover these use cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168473 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-04Driver: Link crtfastmath.o if it's available and -ffast-math is specified.Benjamin Kramer
crtfastmath.o contains routines to set the floating point flags to a faster, unsafe mode. Linking it in speeds up code dealing with denormals significantly (PR14024). For now this is only enabled on linux where I can test it and crtfastmath.o is widely available. We may want to provide a similar file with compiler-rt eventually and/or enable it on other platforms too. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165240 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-20Restructure how the driver communicates information about theJohn McCall
target Objective-C runtime down to the frontend: break this down into a single target runtime kind and version, and compute all the relevant information from that. This makes it relatively painless to add support for new runtimes to the compiler. Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z, available at the driver level as a better and more general alternative to -fgnu-runtime and -fnext-runtime. This new concept of an Objective-C runtime also encompasses what we were previously separating out as the "Objective-C ABI", so fragile vs. non-fragile runtimes are now really modelled as different kinds of runtime, paving the way for better overall differentiation. As a sort of special case, continue to accept the -cc1 flag -fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak. I won't go so far as to say "no functionality change", even ignoring the new driver flag, but subtle changes in driver semantics are almost certainly not intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158793 91177308-0d34-0410-b5e6-96231b3b80d8

option. On the driver, check if we are using libraries from gcc 4.7 or newer and if so pass -fuse-init-array to the frontend. The crtbegin*.o files in gcc 4.7 no longer call the constructors listed in .ctors, so we have to use .init_array. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158694 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-21Duplicated code is bad. At least make it consistent.Bob Wilson
The getARMTargetCPU and getLLVMArchSuffixForARM functions exist in both Toolchain.cpp and Tools.cpp. This stuff needs a thorough overhaul. In the meantime, this patch at least makes them consistent. One version had been converted to use StringSwitch, and the other version had new Cortex M-series processors added. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153202 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-21For Darwin, do not let -mcpu override the -arch option. <rdar://11059238>Bob Wilson
On Darwin the architecture and the corresponding Mach-O slice is typically specified with -arch. If not, it defaults to the current host architecture. Do not use -mcpu to override the -arch value. This is only an issue when people need to use specialized code for a non-default CPU (hopefully guarded by run-time checks to detect the current processor). The -mcpu option is still used for the -target-cpu option to clang, but this patch causes it to not be used to set the architecture in the target triple. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153197 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-31Revert r149083 which is not the direction we're going in the ClangChandler Carruth
driver based on discussions with Doug Gregor. There are several issues: 1) The patch was not reviewed prior to commit and there were review comments. 2) The design of the functionality (triple-prefixed tool invocation) isn't the design we want for Clang going forward: it focuses on the "user triple" rather than on the "toolchain triple", and forces that bit of state into the API of every single toolchain instead of handling it automatically in the common base classes. 3) The tests provided are not stable. They fail on a few Linux variants (Gentoo among them) and on mingw32 and some other environments. I *am* interested in the Clang driver being able to invoke triple-prefixed tools, but we need to design that feature the right way. This patch just extends the previous hack without fixing the underlying problems with it. I'm working on a new design for this that I will mail for review by tomorrow. I am aware that this removes functionality that NetBSD relies on, but this is ToT, not a release. This functionality hasn't been properly designed, implemented, and tested yet. We can't "regress" until we get something that really works, both with the immediate use cases and with long term maintenance of the Clang driver. For reference, the original commit log: Keep track of the original target the user specified before normalization. This used to be captured in DefaultTargetTriple and is used for the (optional) $triple-$tool lookup for cross-compilation.

2012-01-25Switch the ToolChain types to all store a Driver reference rather thanChandler Carruth
a HostInfo reference. Nothing about the HostInfo was used by any toolchain except digging out the driver from it. This just makes that a lot more direct. The change was accomplished entirely mechanically. It's one step closer to removing the shim full of buggy copy/paste code that is HostInfo. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148945 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.

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
