* Use std::error_code instead of llvm::error_code.Rafael Espindola2014-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea of this patch is to turn llvm/Support/system_error.h into a transitional header that just brings in the erorr_code api to the llvm namespace. I will remove it shortly afterwards. The cases where the general idea needed some tweaking: * std::errc is a namespace in msvc, so we cannot use "using std::errc". I could add an #ifdef, but there were not that many uses, so I just added std:: to them in this patch. * Template specialization had to be moved to the std namespace in this patch set already. * The msvc implementation of default_error_condition doesn't seem to provide the same transformations as we need. Not too surprising since the standard doesn't actually say what "equivalent" means. I fixed the problem by keeping our old mapping and using it at error_code construction time. Despite these shortcomings I think this is still a good thing. Some reasons: * The different implementations of system_error might improve over time. * It removes 925 lines of code from llvm already. * It removes 6313 bytes from the text segment of the clang binary when it is built with gcc and 2816 bytes when building with clang and libstdc++. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210687 91177308-0d34-0410-b5e6-96231b3b80d8

* [X86] Refactor the logic to select horizontal adds/subs to a helper function.Andrea Di Biagio2014-06-11
| | | | | | | | | | | | | | | | | This patch moves part of the logic implemented by the target specific combine rules added at r210477 to a separate helper function. This should make easier to add more rules for matching AVX/AVX2 horizontal adds/subs. This patch also fixes a problem caused by a wrong check performed on indices of extract_vector_elt dag nodes in input to the scalar adds/subs. New tests have been added to verify that we correctly check indices of extract_vector_elt dag nodes when selecting a horizontal operation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210644 91177308-0d34-0410-b5e6-96231b3b80d8

* MC: add enumeration of WinEH data encodingSaleem Abdulrasool2014-06-11
| | | | | | | | | | | | | | | Most Windows platforms use auxiliary data for unwinding. This information is stored in the .pdata section. The encoding format for the data differs between architectures and Windows variants. Windows MIPS and Alpha use identical formats; Alpha64 is the same with different widths. Windows x86_64 and Itanium share the representation. All Windows CE entries are identical irrespective of the architecture. ARMv7 (Windows [NT] on ARM) has its own format. This enumeration will become the differentiator once the windows EH emission infrastructure is generalised, allowing us to emit the necessary unwinding information for Windows on ARM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210634 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove support for runtime multi-threading.Zachary Turner2014-06-10
| | | | | | | | | | | | | | | | | | | | | This patch removes the functions llvm_start_multithreaded() and llvm_stop_multithreaded(), and changes llvm_is_multithreaded() to return a constant value based on the value of the compile-time definition LLVM_ENABLE_THREADS. Previously, it was possible to have compile-time support for threads on, and runtime support for threads off, in which case certain mutexes were not allocated or ever acquired. Now, if the build is created with threads enabled, mutexes are always acquired. A test before/after patch of compiling a very large TU showed no noticeable performance impact of this change.
