From 3a610ebf1e7c44309880b2bd7ec9325d3f1db0bd Mon Sep 17 00:00:00 2001 From: Ulrich Weigand Date: Wed, 1 Apr 2015 12:54:25 +0000 Subject: [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 --- clang/test/Preprocessor/predefined-arch-macros.c | 27 ++++++++++++++++++++++++ 1 file changed, 27 insertions(+) (limited to 'clang/test/Preprocessor/predefined-arch-macros.c') diff --git a/clang/test/Preprocessor/predefined-arch-macros.c b/clang/test/Preprocessor/predefined-arch-macros.c index 6e3743da951..9fee3b62940 100644 --- a/clang/test/Preprocessor/predefined-arch-macros.c +++ b/clang/test/Preprocessor/predefined-arch-macros.c @@ -1675,3 +1675,30 @@ // // CHECK_PPC_CRYPTO_M64: #define __CRYPTO__ // + +// Begin SystemZ/GCC/Linux tests ---------------- +// +// RUN: %clang -march=z10 -E -dM %s -o - 2>&1 \ +// RUN: -target s390x-unknown-linux \ +// RUN: | FileCheck %s -check-prefix=CHECK_SYSTEMZ_Z10 +// +// CHECK_SYSTEMZ_Z10: #define __LONG_DOUBLE_128__ 1 +// CHECK_SYSTEMZ_Z10: #define __s390__ 1 +// CHECK_SYSTEMZ_Z10: #define __s390x__ 1 +// CHECK_SYSTEMZ_Z10: #define __zarch__ 1 +// +// RUN: %clang -march=zEC12 -E -dM %s -o - 2>&1 \ +// RUN: -target s390x-unknown-linux \ +// RUN: | FileCheck %s -check-prefix=CHECK_SYSTEMZ_ZEC12 +// +// CHECK_SYSTEMZ_ZEC12: #define __HTM__ 1 +// CHECK_SYSTEMZ_ZEC12: #define __LONG_DOUBLE_128__ 1 +// CHECK_SYSTEMZ_ZEC12: #define __s390__ 1 +// CHECK_SYSTEMZ_ZEC12: #define __s390x__ 1 +// CHECK_SYSTEMZ_ZEC12: #define __zarch__ 1 +// +// RUN: %clang -mhtm -E -dM %s -o - 2>&1 \ +// RUN: -target s390x-unknown-linux \ +// RUN: | FileCheck %s -check-prefix=CHECK_SYSTEMZ_HTM +// +// CHECK_SYSTEMZ_HTM: #define __HTM__ 1 -- cgit v1.2.3
