getCSInfos()

CallsiteInfoList& llvm::StackMaps::getCSInfos ( )

inline

Get call site info.

Definition at line 284 of file StackMaps.h.

getFnInfos()

FnInfoMap& llvm::StackMaps::getFnInfos ( )

inline

Get function info.

recordPatchPoint()

void StackMaps::recordPatchPoint

(

const MachineInstr &

MI

)

Generate a stackmap record for a patchpoint instruction.

References assert(), llvm::MachineInstr::getOpcode(), llvm::MachineInstr::operands_begin(), llvm::MachineInstr::operands_end(), and llvm::StackMaps::Location::Register.

Referenced by EmitNop(), and EmitNops().

recordStackMap()

void StackMaps::recordStackMap

(

const MachineInstr &

MI

)

Generate a stackmap record for a stackmap instruction.

MI must be a raw STACKMAP, not a PATCHPOINT.

recordStatepoint()

void StackMaps::recordStatepoint

(

const MachineInstr &

MI

)

Generate a stackmap record for a statepoint instruction.

Definition at line 394 of file StackMaps.cpp.

reset()

void llvm::StackMaps::reset ( )

inline

Definition at line 233 of file StackMaps.h.

Referenced by llvm::SystemZAsmPrinter::doInitialization(), and llvm::X86AsmPrinter::doInitialization().

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.
