Member Function Documentation

getCSInfos()

CallsiteInfoList & llvm::StackMaps::getCSInfos ( )

inline

Get call site info.

Definition at line 354 of file StackMaps.h.

getFnInfos()

FnInfoMap & llvm::StackMaps::getFnInfos ( )

inline

Get function info.

Definition at line 357 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 170 of file StackMaps.cpp.

recordPatchPoint()

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

Generate a stackmap record for a patchpoint instruction.

Definition at line 539 of file StackMaps.cpp.

References assert(), llvm::PatchPointOpers::getID(), llvm::PatchPointOpers::getNumCallArgs(), llvm::PatchPointOpers::getStackMapStartIdx(), llvm::PatchPointOpers::hasDef(), llvm::PatchPointOpers::isAnyReg(), MI, and llvm::StackMaps::Location::Register.

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 529 of file StackMaps.cpp.

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

recordStatepoint()

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

Generate a stackmap record for a statepoint instruction.

Definition at line 560 of file StackMaps.cpp.

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

reset()

void llvm::StackMaps::reset ( )

inline

Definition at line 303 of file StackMaps.h.

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.
