Member Function Documentation

beginBasicBlockSection()

virtual void llvm::AsmPrinterHandler::beginBasicBlockSection ( const MachineBasicBlock & MBB )

inlinevirtual

Process the beginning of a new basic-block-section within a function.

Always called immediately after beginFunction for the first basic-block. When basic-block-sections are enabled, called before the first block of each such section.

Reimplemented in llvm::DebugHandlerBase, and llvm::DwarfCFIException.

Definition at line 59 of file AsmPrinterHandler.h.

References MBB.

beginCodeAlignment()

virtual void llvm::AsmPrinterHandler::beginCodeAlignment ( const MachineBasicBlock & MBB )

inlinevirtual

Reimplemented in llvm::DwarfDebug.

Definition at line 78 of file AsmPrinterHandler.h.

References MBB.

beginFunclet()

virtual void llvm::AsmPrinterHandler::beginFunclet ( const MachineBasicBlock & MBB, MCSymbol * Sym = nullptr )

inlinevirtual

Emit target-specific EH funclet machinery.

Reimplemented in llvm::WinException.

Definition at line 81 of file AsmPrinterHandler.h.

References MBB.

beginFunction()

virtual void llvm::AsmPrinterHandler::beginFunction ( const MachineFunction * MF )

pure virtual

Gather pre-function debug information.

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

Implemented in llvm::AIXException, llvm::ARMException, llvm::DebugHandlerBase, llvm::DwarfCFIException, llvm::WasmException, llvm::WinCFGuard, and llvm::WinException.

References markFunctionEnd().

beginInstruction()

virtual void llvm::AsmPrinterHandler::beginInstruction ( const MachineInstr * MI )

inlinevirtual

Process beginning of an instruction.

Reimplemented in llvm::BTFDebug, llvm::CodeViewDebug, llvm::DebugHandlerBase, and llvm::DwarfDebug.

Definition at line 73 of file AsmPrinterHandler.h.

References MI.

beginModule()

virtual void llvm::AsmPrinterHandler::beginModule ( Module * M )

inlinevirtual

Reimplemented in llvm::CodeViewDebug, llvm::DebugHandlerBase, and llvm::DwarfDebug.

Definition at line 38 of file AsmPrinterHandler.h.

endBasicBlockSection()

virtual void llvm::AsmPrinterHandler::endBasicBlockSection ( const MachineBasicBlock & MBB )

inlinevirtual

Process the end of a basic-block-section within a function.

When basic-block-sections are enabled, called after the last block in each such section (including the last section in the function). When basic-block-sections are disabled, called at the end of a function, immediately prior to markFunctionEnd.

Reimplemented in llvm::DebugHandlerBase, and llvm::DwarfCFIException.

Definition at line 66 of file AsmPrinterHandler.h.

References MBB.

endFunclet()

virtual void llvm::AsmPrinterHandler::endFunclet ( )

inlinevirtual

Reimplemented in llvm::WinException.

Definition at line 83 of file AsmPrinterHandler.h.

endFunction()

virtual void llvm::AsmPrinterHandler::endFunction ( const MachineFunction * MF )

pure virtual

Gather post-function debug information.

Implemented in llvm::AIXException, llvm::ARMException, llvm::DebugHandlerBase, llvm::DwarfCFIException, llvm::WasmException, llvm::WinCFGuard, and llvm::WinException.

endInstruction()

virtual void llvm::AsmPrinterHandler::endInstruction ( )

inlinevirtual

Process end of an instruction.

Reimplemented in llvm::DebugHandlerBase.

Definition at line 76 of file AsmPrinterHandler.h.

endModule()

virtual void llvm::AsmPrinterHandler::endModule ( )

pure virtual

Emit all sections that should come after the content.

Implemented in llvm::AIXException, llvm::ARMException, llvm::BTFDebug, llvm::CodeViewDebug, llvm::DwarfCFIException, llvm::DwarfDebug, llvm::WasmException, llvm::WinCFGuard, and llvm::WinException.

markFunctionEnd()

void AsmPrinterHandler::markFunctionEnd ( )

virtual

Reimplemented in llvm::ARMException, and llvm::WinException.

Definition at line 4707 of file AsmPrinter.cpp.

Referenced by beginFunction().

setSymbolSize()

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

inlinevirtual

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

common symbols), this tracks that size.

Reimplemented in llvm::DwarfDebug.

Definition at line 70 of file AsmPrinterHandler.h.
