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 39 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 32 of file WinCFGuard.cpp.

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

endModule()

void WinCFGuard::endModule ( )

overridevirtual

Emit the Control Flow Guard function ID table.

Implements llvm::AsmPrinterHandler.

Definition at line 84 of file WinCFGuard.cpp.
