class  llvm::X86InstrInfo


namespace  llvm
 This is an optimization pass for GlobalISel generic memory operations.
namespace  llvm::X86
 Define some predicates that are used for node matching.




enum  llvm::X86::AsmComments { llvm::X86::AC_EVEX_2_VEX = MachineInstr::TAsmComments }


std::pair< CondCode, boolllvm::X86::getX86ConditionCode (CmpInst::Predicate Predicate)
 Return a pair of condition code for the given predicate and whether the instruction operands should be swaped to match the condition code.
unsigned llvm::X86::getCMovOpcode (unsigned RegBytes, bool HasMemoryOperand=false)
 Return a cmov opcode for the given register size in bytes, and operand type.
int llvm::X86::getCondSrcNoFromDesc (const MCInstrDesc &MCID)
 Return the source operand # for condition code by MCID.
CondCode llvm::X86::getCondFromMI (const MachineInstr &MI)
 Return the condition code of the instruction.
CondCode llvm::X86::getCondFromBranch (const MachineInstr &MI)
CondCode llvm::X86::getCondFromSETCC (const MachineInstr &MI)
CondCode llvm::X86::getCondFromCMov (const MachineInstr &MI)
CondCode llvm::X86::GetOppositeBranchCondition (CondCode CC)
 GetOppositeBranchCondition - Return the inverse of the specified cond, e.g.
unsigned llvm::X86::getVPCMPImmForCond (ISD::CondCode CC)
 Get the VPCMP immediate for the given condition.
unsigned llvm::X86::getSwappedVPCMPImm (unsigned Imm)
 Get the VPCMP immediate if the opcodes are swapped.
unsigned llvm::X86::getSwappedVPCOMImm (unsigned Imm)
 Get the VPCOM immediate if the opcodes are swapped.
unsigned llvm::X86::getSwappedVCMPImm (unsigned Imm)
 Get the VCMP immediate if the opcodes are swapped.
bool llvm::X86::isX87Instruction (MachineInstr &MI)
 Check if the instruction is X87 instruction.
static bool llvm::isGlobalStubReference (unsigned char TargetFlag)
 isGlobalStubReference - Return true if the specified TargetFlag operand is a reference to a stub for a global, not the global itself.
static bool llvm::isGlobalRelativeToPICBase (unsigned char TargetFlag)
 isGlobalRelativeToPICBase - Return true if the specified global value reference is relative to a 32-bit PIC base (X86ISD::GlobalBaseReg).
static bool llvm::isScale (const MachineOperand &MO)
static bool llvm::isLeaMem (const MachineInstr &MI, unsigned Op)
static bool llvm::isMem (const MachineInstr &MI, unsigned Op)
