◆ changeSection()

void NVPTXTargetStreamer::changeSection	(	const MCSection *	CurSection,
		MCSection *	Section,
		uint32_t	SubSection,
		raw_ostream &	OS )

overridevirtual

Update streamer for a new active section.

This is called by popSection and switchSection, if the current section changes.

Reimplemented from llvm::MCTargetStreamer.

Definition at line 87 of file NVPTXTargetStreamer.cpp.

References assert(), llvm::MCStreamer::getContext(), llvm::MCContext::getObjectFileInfo(), llvm::MCTargetStreamer::getStreamer(), isDwarfSection(), and outputDwarfFileDirectives().

◆ closeLastSection()

void NVPTXTargetStreamer::closeLastSection ( )

Close last section.

◆ emitAddressSizeDirective()

virtual void llvm::NVPTXTargetStreamer::emitAddressSizeDirective ( unsigned AddrSize )

inlinevirtual

Emit address size used for this PTX module.

Reimplemented in llvm::NVPTXAsmTargetStreamer.

Definition at line 42 of file NVPTXTargetStreamer.h.

◆ emitAliasDirective()

virtual void llvm::NVPTXTargetStreamer::emitAliasDirective	(	const MCSymbol *	Name,
		const MCSymbol *	Aliasee )

inlinevirtual

Emit an alias from Name to Aliasee.

Reimplemented in llvm::NVPTXAsmTargetStreamer.

Definition at line 58 of file NVPTXTargetStreamer.h.

◆ emitBanner()

virtual void llvm::NVPTXTargetStreamer::emitBanner ( )

inlinevirtual

Emit the banner which specifies details of PTX generator.

Reimplemented in llvm::NVPTXAsmTargetStreamer.

Definition at line 32 of file NVPTXTargetStreamer.h.

◆ emitBranchTargetsDirective()

virtual void llvm::NVPTXTargetStreamer::emitBranchTargetsDirective ( ArrayRef< const MCSymbol * > Targets )

inlinevirtual

Emit the list of branch targets a brx.idx may jump to.

Reimplemented in llvm::NVPTXAsmTargetStreamer.

Definition at line 45 of file NVPTXTargetStreamer.h.

◆ emitDwarfFileDirective()

void NVPTXTargetStreamer::emitDwarfFileDirective ( StringRef Directive )

overridevirtual

Record DWARF file directives for later output.

According to PTX ISA, CUDA Toolkit documentation, 11.5.3. Debugging Directives: .file (http://docs.nvidia.com/cuda/parallel-thread-execution/index.html#debugging-directives-file), The .file directive is allowed only in the outermost scope, i.e., at the same level as kernel and device function declarations. Also, the order of the .loc and .file directive does not matter, .file directives may follow the .loc directives where the file is referenced. LLVM emits .file directives immediately the location debug info is emitted, i.e. they may be emitted inside functions. We gather all these directives and emit them outside of the sections and, thus, outside of the functions.

Reimplemented from llvm::MCTargetStreamer.

Definition at line 43 of file NVPTXTargetStreamer.cpp.
