Methods

¶PseudoProbeHandler(llvm::AsmPrinter* A)

Declared at: llvm/lib/CodeGen/AsmPrinter/PseudoProbePrinter.h:31

Parameters

llvm::AsmPrinter* A

¶void beginFunction(
    const llvm::MachineFunction* MF)

Description

Gather pre-function debug information. Every beginFunction(MF) call should be followed by an endFunction(MF) call.

Declared at: llvm/lib/CodeGen/AsmPrinter/PseudoProbePrinter.h:40

Parameters

const llvm::MachineFunction* MF

¶void beginInstruction(
    const llvm::MachineInstr* MI)

Description

Process beginning of an instruction.

Declared at: llvm/lib/CodeGen/AsmPrinter/PseudoProbePrinter.h:42

Parameters

const llvm::MachineInstr* MI

¶void emitPseudoProbe(
    uint64_t Guid,
    uint64_t Index,
    uint64_t Type,
    uint64_t Attr,
    const llvm::DILocation* DebugLoc)

Declared at: llvm/lib/CodeGen/AsmPrinter/PseudoProbePrinter.h:34

Parameters

uint64_t Guid

uint64_t Index

uint64_t Type

uint64_t Attr

const llvm::DILocation* DebugLoc

¶void endFunction(const llvm::MachineFunction* MF)

Description

Gather post-function debug information. Please note that some AsmPrinter implementations may not call beginFunction at all.

Declared at: llvm/lib/CodeGen/AsmPrinter/PseudoProbePrinter.h:41

Parameters

const llvm::MachineFunction* MF

¶void endInstruction()

Description

Process end of an instruction.

Declared at: llvm/lib/CodeGen/AsmPrinter/PseudoProbePrinter.h:43

¶void endModule()

Description

Emit all sections that should come after the content.

Declared at: llvm/lib/CodeGen/AsmPrinter/PseudoProbePrinter.h:39

¶void setSymbolSize(const llvm::MCSymbol* Sym,
                   uint64_t Size)

Description

For symbols that have a size designated (e.g. common symbols), this tracks that size.

Declared at: llvm/lib/CodeGen/AsmPrinter/PseudoProbePrinter.h:38

Parameters

const llvm::MCSymbol* Sym

uint64_t Size

¶~PseudoProbeHandler()

Description

Pin vtable to this file.
