Add a comment that can be emitted to the generated .s file to make the output of the compiler more readable.

This only affects the MCAsmStreamer and only when verbose assembly output is enabled.

Emit nops until the byte alignment ByteAlignment is reached.

This used to align code where the alignment bytes may be executed. This can emit different bytes for different sizes to optimize execution.

Parameters
Alignment- The alignment to reach.
STI- The MCSubtargetInfo in operation when padding is emitted.
MaxBytesToEmit- The maximum numbers of bytes to emit, or 0. If the alignment cannot be reached in this many bytes, no bytes are emitted.

unsigned  Size,
bool  Parens = false 
)

◆ emitInstruction()

void SystemZHLASMAsmStreamer::emitInstruction ( const MCInst Inst,
const MCSubtargetInfo STI 
)
overridevirtual

Emit the given Instruction into the current section.

Reimplemented from llvm::MCStreamer.

Definition at line 179 of file SystemZHLASMAsmStreamer.cpp.

References EmitEOL().

◆ emitLabel()

void SystemZHLASMAsmStreamer::emitLabel ( MCSymbol Symbol,
SMLoc  Loc 
)
overridevirtual

Emit a label for Symbol into the current section.

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.

◆ 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.

bool llvm::SystemZHLASMAsmStreamer::hasRawTextSupport ( ) const
inlineoverridevirtual

Do we support EmitRawText?

◆ isVerboseAsm()

bool llvm::SystemZHLASMAsmStreamer::isVerboseAsm ( ) const
