Member Function Documentation

getCSInfos()

CallsiteInfoList& llvm::StackMaps::getCSInfos ( )

inline

Get call site info.

Definition at line 348 of file StackMaps.h.

getFnInfos()

FnInfoMap& llvm::StackMaps::getFnInfos ( )

inline

Get function info.

Definition at line 351 of file StackMaps.h.

getNextMetaArgIdx()

unsigned StackMaps::getNextMetaArgIdx ( const MachineInstr *  MI, unsigned  CurIdx  )

static

Get index of next meta operand.

Similar to parseOperand, but does not actually parses operand meaning.

Definition at line 154 of file StackMaps.cpp.

References assert(), llvm_unreachable, and MI.

Referenced by llvm::MachineInstr::findTiedOperandIdx(), llvm::StatepointOpers::getNumAllocaIdx(), llvm::StatepointOpers::getNumGcMapEntriesIdx(), and llvm::StatepointOpers::getNumGCPtrIdx().

recordPatchPoint()

void StackMaps::recordPatchPoint	(	const MCSymbol &	L,
		const MachineInstr &	MI
	)

Generate a stackmap record for a patchpoint instruction.

Definition at line 534 of file StackMaps.cpp.

recordStackMap()

void StackMaps::recordStackMap	(	const MCSymbol &	L,
		const MachineInstr &	MI
	)

Generate a stackmap record for a stackmap instruction.

MI must be a raw STACKMAP, not a PATCHPOINT.

Definition at line 524 of file StackMaps.cpp.

References assert(), llvm::StackMapOpers::getVarIdx(), llvm::PatchPointOpers::IDPos, MI, and llvm::ISD::STACKMAP.

recordStatepoint()

void StackMaps::recordStatepoint	(	const MCSymbol &	L,
		const MachineInstr &	MI
	)

Generate a stackmap record for a statepoint instruction.

Definition at line 555 of file StackMaps.cpp.

References assert(), llvm::StatepointOpers::getID(), llvm::StatepointOpers::getVarIdx(), and MI.

reset()

void llvm::StackMaps::reset ( )

inline

Definition at line 294 of file StackMaps.h.

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

serializeToStackMapSection()

void StackMaps::serializeToStackMapSection

(

)

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

Serialize the stackmap data.

This clears the stack map data structures afterwards.
