[SystemZ] Support transactional execution on zEC12 The zEC12 provides the transactional-execution facility. This is exposed to users via a set of builtin routines on other compilers. This patch adds clang support to enable those builtins. In partciular, the patch: - enables the transactional-execution feature by default on zEC12 - allows to override presence of that feature via the -mhtm/-mno-htm options - adds a predefined macro __HTM__ if the feature is enabled - adds support for the transactional-execution GCC builtins - adds Sema checking to verify the __builtin_tabort abort code - adds the s390intrin.h header file (for GCC compatibility) - adds s390 sections to the htmintrin.h and htmxlintrin.h header files Since this is first use of target-specific intrinsics on the platform, the patch creates the include/clang/Basic/BuiltinsSystemZ.def file and hooks it up in TargetBuiltins.h and lib/Basic/Targets.cpp. An associated LLVM patch adds the required LLVM IR intrinsics. For reference, the transactional-execution instructions are documented in the z/Architecture Principles of Operation for the zEC12: http://publibfp.boulder.ibm.com/cgi-bin/bookmgr/download/DZ9ZR009.pdf The associated builtins are documented in the GCC manual: http://gcc.gnu.org/onlinedocs/gcc/S_002f390-System-z-Built-in-Functions.html The htmxlintrin.h intrinsics provided for compatibility with the IBM XL compiler are documented in the "z/OS XL C/C++ Programming Guide". llvm-svn: 233804 2015-04-01 20:54:25 +08:00			`/*===---- s390intrin.h - SystemZ intrinsics --------------------------------===`

Move the builtin headers to use the new license file header. Summary: These all had somewhat custom file headers with different text from the ones I searched for previously, and so I missed them. Thanks to Hal and Kristina and others who prompted me to fix this, and sorry it took so long.

[SystemZ] Add support for vecintrin.h vector built-in functions This patch adds support for the System Z vector built-in functions. The API-defined header file has the name vecintrin.h. The user-level functions are defined in the same style as the clang version of altivec.h, making heavy use of the __overloadable__ and __always_inline__ attributes. Where possible the functions expand to generic operations rather than specific built-in functions, in the hope that that form can be optimised better. Where a built-in routine is specified to require an immediate integer argument, the __enable_if__ attribute is used to verify the argument is in fact constant and in the appropriate range. Based on a patch by Richard Sandiford. llvm-svn: 243643 2015-07-30 22:10:43 +08:00			`#ifdef __VEC__`
