Member Function Documentation

void StackMaps::recordPatchPoint ( const MachineInstr & MI )

Generate a stackmap record for a patchpoint instruction.

Definition at line 257 of file StackMaps.cpp.

References llvm::MachineInstr::getOpcode(), llvm::PatchPointOpers::IDPos, llvm::PatchPointOpers::NArgPos, llvm::MachineInstr::operands_begin(), llvm::MachineInstr::operands_end(), llvm::TargetOpcode::PATCHPOINT, and llvm::StackMaps::Location::Register.

void StackMaps::recordStackMap ( const MachineInstr & MI )

Generate a stackmap record for a stackmap instruction.

MI must be a raw STACKMAP, not a PATCHPOINT.

void llvm::StackMaps::reset ( ) [inline]

Definition at line 121 of file StackMaps.h.

References llvm::MapVector< KeyT, ValueT, MapType, VectorType >::clear().

void StackMaps::serializeToStackMapSection ( )

Serialize the stackmap data.

If there is any stack map data, create a stack map section and serialize the map info into it. This clears the stack map data structures afterwards.
