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

Enumerations
enum	llvm::X86::RoundingMode {   llvm::X86::rmInvalid = -1 , llvm::X86::rmToNearest = 0 , llvm::X86::rmDownward = 1 << 10 , llvm::X86::rmUpward = 2 << 10 ,   llvm::X86::rmTowardZero = 3 << 10 , llvm::X86::rmMask = 3 << 10 }
	Current rounding mode is represented in bits 11:10 of FPSR. More...

Functions
bool	llvm::X86::isZeroNode (SDValue Elt)
	Returns true if Elt is a constant zero or floating point constant +0.0.
bool	llvm::X86::isOffsetSuitableForCodeModel (int64_t Offset, CodeModel::Model M, bool hasSymbolicDisplacement)
	Returns true of the given offset can be fit into displacement field of the instruction.
bool	llvm::X86::isCalleePop (CallingConv::ID CallingConv, bool is64Bit, bool IsVarArg, bool GuaranteeTCO)
	Determines whether the callee is required to pop its own arguments.
bool	llvm::X86::isConstantSplat (SDValue Op, APInt &SplatVal, bool AllowPartialUndefs=true)
	If Op is a constant whose elements are all the same constant or undefined, return true and return the constant value in SplatVal.
bool	llvm::X86::mayFoldLoad (SDValue Op, const X86Subtarget &Subtarget, bool AssumeSingleUse=false, bool IgnoreAlignment=false)
	Check if Op is a load operation that could be folded into some other x86 instruction as a memory operand.
bool	llvm::X86::mayFoldLoadIntoBroadcastFromMem (SDValue Op, MVT EltVT, const X86Subtarget &Subtarget, bool AssumeSingleUse=false)
	Check if Op is a load operation that could be folded into a vector splat instruction as a memory operand.
bool	llvm::X86::mayFoldIntoStore (SDValue Op)
	Check if Op is a value that could be used to fold a store into some other x86 instruction as a memory operand.
bool	llvm::X86::mayFoldIntoZeroExtend (SDValue Op)
	Check if Op is an operation that could be folded into a zero extend x86 instruction.
bool	llvm::X86::isExtendedSwiftAsyncFrameSupported (const X86Subtarget &Subtarget, const MachineFunction &MF)
	True if the target supports the extended frame for async Swift functions.
int	llvm::X86::getRoundingModeX86 (unsigned RM)
	Convert LLVM rounding mode to X86 rounding mode.
FastISel *	llvm::X86::createFastISel (FunctionLoweringInfo &funcInfo, const TargetLibraryInfo *libInfo, const LibcallLoweringInfo *libcallLowering)
void	llvm::createUnpackShuffleMask (EVT VT, SmallVectorImpl< int > &Mask, bool Lo, bool Unary)
	Generate unpacklo/unpackhi shuffle mask.
void	llvm::createSplat2ShuffleMask (MVT VT, SmallVectorImpl< int > &Mask, bool Lo)
	Similar to unpacklo/unpackhi, but without the 128-bit lane limitation imposed by AVX and specific to the unary pattern.
