Member Function Documentation

beginFunction()

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

inlineoverridevirtual

Gather pre-function debug information.

Every beginFunction(MF) call should be followed by an endFunction(MF) call.

Implements llvm::AsmPrinterHandler.

Definition at line 41 of file WinCFGuard.h.

beginInstruction()

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

inlineoverridevirtual

Process beginning of an instruction.

Implements llvm::AsmPrinterHandler.

Definition at line 49 of file WinCFGuard.h.

endFunction()

void WinCFGuard::endFunction ( const MachineFunction *  MF )

overridevirtual

Gather post-function debug information.

Please note that some AsmPrinter implementations may not call beginFunction at all.

Implements llvm::AsmPrinterHandler.

Definition at line 31 of file WinCFGuard.cpp.

References llvm::append_range(), and llvm::MachineFunction::getLongjmpTargets().

endInstruction()

void llvm::WinCFGuard::endInstruction ( )

inlineoverridevirtual

Process end of an instruction.

Implements llvm::AsmPrinterHandler.

Definition at line 52 of file WinCFGuard.h.

endModule()

void WinCFGuard::endModule ( )

overridevirtual

Emit the Control Flow Guard function ID table.

Implements llvm::AsmPrinterHandler.

Definition at line 83 of file WinCFGuard.cpp.

setSymbolSize()

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

inlineoverridevirtual

For symbols that have a size designated (e.g.

common symbols), this tracks that size.

Implements llvm::AsmPrinterHandler.
