Member Function Documentation

◆ getID()

uint64_t llvm::StackMapOpers::getID ( ) const
inline

Return the ID for the given stackmap.

Definition at line 48 of file StackMaps.h.

References llvm::MachineOperand::getImm(), llvm::MachineInstr::getOperand(), and IDPos.

◆ getNumPatchBytes()

uint32_t llvm::StackMapOpers::getNumPatchBytes ( ) const
inline

Return the number of patchable bytes the given stackmap should emit.

Definition at line 51 of file StackMaps.h.

References llvm::MachineOperand::getImm(), and llvm::MachineInstr::getOperand().

Referenced by llvm::AArch64InstrInfo::getInstSizeInBytes(), and llvm::PPCInstrInfo::getInstSizeInBytes().

◆ getVarIdx()

unsigned llvm::StackMapOpers::getVarIdx ( ) const
inline

Get the operand index of the variable list of non-argument operands.

These hold the "live state".
