Detailed Description

Streaming machine code generation interface.

This interface is intended to provide a programatic 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.

◆ 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.
