[x86] regenerate test checks, add 64-bit run; NFC llvm-svn: 310767
2017-08-12 06:05:33 +08:00
; NOTE: Assertions have been autogenerated by utils/update_llc_test_checks.py
; RUN: llc < %s -mtriple=i686-unknown-unknown | FileCheck %s --check-prefix=X32

Define patterns for shld and shrd that match immediate shift counts, and patterns that match dynamic shift counts when the subtract is obscured by a truncate node. Add DAGCombiner support for recognizing rotate patterns when the shift counts are defined by truncate nodes. Fix and simplify the code for commuting shld and shrd instructions to work even when the given instruction doesn't have a parent, and when the caller needs a new instruction. These changes allow LLVM to use the shld, shrd, rol, and ror instructions on x86 to replace equivalent code using two shifts and an or in many more cases. llvm-svn: 57662

Define patterns for shld and shrd that match immediate shift counts, and patterns that match dynamic shift counts when the subtract is obscured by a truncate node. Add DAGCombiner support for recognizing rotate patterns when the shift counts are defined by truncate nodes. Fix and simplify the code for commuting shld and shrd instructions to work even when the given instruction doesn't have a parent, and when the caller needs a new instruction. These changes allow LLVM to use the shld, shrd, rol, and ror instructions on x86 to replace equivalent code using two shifts and an or in many more cases. llvm-svn: 57662
