This corresponds to an assembler statement such as: foo:

Parameters

Symbol - The symbol to emit. A given symbol should only be emitted as a label once, and symbols emitted as a label should never be used in an assignment.

◆ emitRawTextImpl()

void SystemZHLASMAsmStreamer::emitRawTextImpl ( StringRef String )

overridevirtual

EmitRawText - If this file is backed by an assembly streamer, this dumps the specified string in the output .s file.

This capability is indicated by the hasRawTextSupport() predicate.

◆ emitSymbolAttribute()

bool llvm::SystemZHLASMAsmStreamer::emitSymbolAttribute	(	MCSymbol *	Symbol,
		MCSymbolAttr	Attribute )

inlineoverridevirtual

Add the given Attribute to Symbol.

Implements llvm::MCStreamer.

◆ emitValueImpl()

void SystemZHLASMAsmStreamer::emitValueImpl	(	const MCExpr *	Value,
		unsigned	Size,
		SMLoc	Loc )

overridevirtual

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.
Loc	- The location of the expression for error reporting.

◆ emitValueToAlignment()

void SystemZHLASMAsmStreamer::emitValueToAlignment	(	Align	Alignment,
		int64_t	Fill,
		uint8_t	FillLen,
		unsigned	MaxBytesToEmit )

overridevirtual

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

Alignment	- The alignment to reach.
Fill	- The value to use when filling bytes.
FillLen	- 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.

◆ emitZerofill()

void llvm::SystemZHLASMAsmStreamer::emitZerofill	(	MCSection *	Section,
		MCSymbol *	Symbol = nullptr,
		uint64_t	Size = 0,
		Align	ByteAlignment = Align(1),
		SMLoc	Loc = SMLoc() )

inlineoverridevirtual

Emit the zerofill section and an optional symbol.

Parameters

Section	- The zerofill section to create and or to put the symbol
Symbol	- The zerofill symbol to emit, if non-NULL.
Size	- The size of the zerofill symbol.
ByteAlignment	- The alignment of the zerofill symbol.

◆ hasRawTextSupport()

bool llvm::SystemZHLASMAsmStreamer::hasRawTextSupport ( ) const

inlineoverridevirtual

Do we support EmitRawText?

bool llvm::SystemZHLASMAsmStreamer::isVerboseAsm ( ) const

inlineoverridevirtual

Return true if this streamer supports verbose assembly at all.
