Member Function Documentation

getID()

uint64_t llvm::StackMapOpers::getID ( ) const

inline

Return the ID for the given stackmap.

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.

getVarIdx()

unsigned llvm::StackMapOpers::getVarIdx ( ) const

inline

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

These hold the "live state".
