Methods

¶static unsigned int CountResults(
    llvm::SDNode* Node)

Description

CountResults - The results of target nodes have register or immediate operands first, then an optional chain, and optional flag operands (which do not go into the machine instrs.)

Declared at: llvm/lib/CodeGen/SelectionDAG/InstrEmitter.h:103

Parameters

llvm::SDNode* Node

¶llvm::MachineInstr* EmitDbgLabel(
    llvm::SDDbgLabel* SD)

Description

Generate machine instruction for a dbg_label node.

Declared at: llvm/lib/CodeGen/SelectionDAG/InstrEmitter.h:111

Parameters

llvm::SDDbgLabel* SD

¶llvm::MachineInstr* EmitDbgValue(
    llvm::SDDbgValue* SD,
    DenseMap<llvm::SDValue, unsigned int>&
        VRBaseMap)

Description

EmitDbgValue - Generate machine instruction for a dbg_value node.

Declared at: llvm/lib/CodeGen/SelectionDAG/InstrEmitter.h:107

Parameters

llvm::SDDbgValue* SD

DenseMap<llvm::SDValue, unsigned int>& VRBaseMap

¶void EmitNode(llvm::SDNode* Node,
              bool IsClone,

¶InstrEmitter(
    llvm::MachineBasicBlock* mbb,
