Unlike LLVM values, Selection DAG nodes may return multiple values as the result of a computation.
Targets can subclass this to parameterize the SelectionDAG lowering and instruction selection process...
This is used to represent a portion of an LLVM function in a low-level Data Dependence DAG representa...
SDValue EmitTargetCodeForMemset(SelectionDAG &DAG, const SDLoc &DL, SDValue Chain, SDValue Dst, SDValue Byte, SDValue Size, Align Alignment, bool IsVolatile, bool AlwaysInline, MachinePointerInfo DstPtrInfo) const override
Emit target-specific code that performs a memset.
std::pair< SDValue, SDValue > EmitTargetCodeForMemchr(SelectionDAG &DAG, const SDLoc &DL, SDValue Chain, SDValue Src, SDValue Char, SDValue Length, MachinePointerInfo SrcPtrInfo) const override
Emit target-specific code that performs a memchr, in cases where that is faster than a libcall.

std::pair< SDValue, SDValue > EmitTargetCodeForStrcmp(SelectionDAG &DAG, const SDLoc &DL, SDValue Chain, SDValue Src1, SDValue Src2, MachinePointerInfo Op1PtrInfo, MachinePointerInfo Op2PtrInfo) const override
Emit target-specific code that performs a strcmp, in cases where that is faster than a libcall.

Emit target-specific code that performs a memcmp/bcmp, in cases where that is faster than a libcall.
This is an optimization pass for GlobalISel generic memory operations.
This struct is a compact representation of a valid (non-zero power of two) alignment.
This class contains a discriminated union of information about pointers in memory operands,...
