void NVPTXTargetStreamer::changeSection	(	const MCSection *	CurSection,

Update streamer for a new active section.

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

◆ 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.
