Functions
std::pair< CondCode, bool > llvm::X86::getX86ConditionCode (CmpInst::Predicate Predicate)

unsigned llvm::X86::getCMovOpcode (unsigned RegBytes, bool HasMemoryOperand=false, bool HasNDD=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.

bool llvm::X86::isX87Instruction (MachineInstr &MI)
Check if the instruction is X87 instruction.
int llvm::X86::getFirstAddrOperandIdx (const MachineInstr &MI)
Return the index of the instruction's first address operand, if it has a memory reference, or -1 if it has none.
const Constant * llvm::X86::getConstantFromPool (const MachineInstr &MI, unsigned OpNo)
Find any constant pool entry associated with a specific instruction operand.
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).
