Detailed Description

MCStreamer - 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 - Add a comment 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

EmitValue - Emit the expression Value into the output as a native integer of the given Size bytes.

This is used to implement assembler directives such as .word, .quad, etc.

Parameters:

Value	- The value to emit.
Size	- The size of the integer (in bytes) to emit. This must match a native machine width.

EmitValueToAlignment - Emit some number of copies of Value until the byte alignment ByteAlignment is reached.

If the number of bytes need to emit for the alignment is not a multiple of ValueSize, then the contents of the emitted fill bytes is undefined.

This used to implement the .align assembler directive.

Parameters:

ByteAlignment	- The alignment to reach. This must be a power of two on some targets.
Value	- The value to use when filling bytes.
ValueSize	- The size of the integer (in bytes) to emit for `Value`. This must match a native machine width.
MaxBytesToEmit	- The maximum numbers of bytes to emit, or 0. If the alignment cannot be reached in this many bytes, no bytes are emitted.

Parameters:

Offset	- The offset to reach. This may be an expression, but the expression must be associated with the current section.
Value	- The value to use when filling bytes.

Returns:: false on success, true if the offset was invalid.

void llvm::MCStreamer::SwitchSectionNoChange	(	const MCSection *	Section,
		const MCExpr *	Subsection = `nullptr`
	)		`[inline]`

SwitchSectionNoChange - Set the current section where code is being emitted to Section. This is required to update CurSection. This version does not call ChangeSection.
