[SystemZ] Support floating-point control register instructions
Add assembler support for instructions manipulating the FPC. Also add codegen support via the GCC compatibility builtins: __builtin_s390_sfpc __builtin_s390_efpc llvm-svn: 288525 |

[SystemZ] Utilize Test Data Class instructions.
This adds a new SystemZ-specific intrinsic, llvm.s390.tdc.f(32|64|128), which maps straight to the test data class instructions. A new IR pass is added to recognize instructions that can be converted to TDC and perform the necessary replacements. Differential Revision: http://reviews.llvm.org/D21949 llvm-svn: 275016 |

Split IntrReadArgMem into IntrReadMem and IntrArgMemOnly
Summary: IntrReadWriteArgMem simply becomes IntrArgMemOnly. So there are fewer intrinsic properties that express their orthogonality better, and correspond more closely to the corresponding IR attributes. Suggested by: Philip Reames Reviewers: joker.eph, reames, tstellarAMD Subscribers: jholewinski, arsenm, llvm-commits Differential Revision: http://reviews.llvm.org/D19291 llvm-svn: 267021 |

[SystemZ] Add vector intrinsics
This adds intrinsics to allow access to all of the z13 vector instructions. Note that instructions whose semantics can be described by standard LLVM IR do not get any intrinsics. For each instructions whose semantics *cannot* (fully) be described, we define an LLVM IR target-specific intrinsic that directly maps to this instruction. For instructions that also set the condition code, the LLVM IR intrinsic returns the post-instruction CC value as a second result. Instruction selection will attempt to detect code that compares that CC value against constants and use the condition code directly instead. Based on a patch by Richard Sandiford. llvm-svn: 236527 |

[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 LLVM support to enable those builtins. In partciular, the patch: - adds the transactional-execution and processor-assist facilities - adds MC support for all instructions provided by those facilities - adds LLVM intrinsics for those instructions and hooks them up for CodeGen - adds CodeGen support to optimize CC return value checking Since this is first use of target-specific intrinsics on the platform, the patch creates the include/llvm/IR/IntrinsicsSystemZ.td file and hooks it up in Intrinsics.td. I've also changed Triple::getArchTypePrefix to return "s390" instead of "systemz", since the naming convention for GCC intrinsics uses "s390" on the platform, and it neemed more straight- forward to use the same convention for LLVM IR intrinsics. An associated clang patch makes the intrinsics (and command line switches) available at the source-language level. 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 Index: llvm-head/lib/Target/SystemZ/SystemZOperators.td =================================================================== --- llvm-head.orig/lib/Target/SystemZ/SystemZOperators.td +++ llvm-head/lib/Target/SystemZ/SystemZOperators.td @@ -79,6 +79,9 @@ def SDT_ZI32Intrinsic : SDTypeProf def SDT_ZPrefetch : SDTypeProfile<0, 2, [SDTCisVT<0, i32>, SDTCisPtrTy<1>]>;
