Detailed Description

Streaming machine code generation interface.

This interface is intended to provide a programmatic interface that is very similar to the level that an assembler .s file provides. It has callbacks to emit bytes, handle directives, etc. The implementation of this interface retains state to know what the current section is etc.

There are multiple implementations of this interface: one for writing out a .s file, and implementations that write out .o files of various formats.

◆ addBlankLine()

virtual void llvm::MCStreamer::addBlankLine ( )

inlinevirtual

Emit a blank line to a .s file to pretty it up.

Definition at line 408 of file MCStreamer.h.

Referenced by llvm::TargetLoweringObjectFileELF::emitModuleMetadata(), llvm::TargetLoweringObjectFileMachO::emitModuleMetadata(), llvm::TargetLoweringObjectFileCOFF::emitModuleMetadata(), and emitNonLazyStubs().

◆ AddComment()

virtual void llvm::MCStreamer::AddComment	(	const Twine &	T,
		bool	EOL = `true`
	)

inlinevirtual

Add a textual comment.

Typically for comments that can be emitted to the generated .s file if applicable as a QoI issue to make the output of the compiler more readable. This only affects the MCAsmStreamer, and only when verbose assembly output is enabled.

If the comment includes embedded
's, they will each get the comment prefix as appropriate. The added comment should not end with a
. By default, each comment is terminated with an end of line, i.e. the EOL param is set to true by default. If one prefers not to end the comment with a new line then the EOL param should be passed with a false value.

◆ emitAssignment()

void MCStreamer::emitAssignment	(	MCSymbol *	Symbol,
		const MCExpr *	Value
	)

virtual

Emit an assignment of Value to Symbol.

This corresponds to an assembler statement such as: symbol = value

The assignment generates no code, but has the side effect of binding the value in the current context. For the assembly streamer, this prints the binding into the .s file.

Parameters

Symbol	- The symbol being assigned to.
Value	- The value for the symbol.
