◆ compareOffsets()

bool clang::CodeGen::CGHLSLOffsetInfo::compareOffsets	(	uint32_t	LHS,
		uint32_t	RHS )

inlinestatic

Comparison function for offsets received from operator[] suitable for use in a stable_sort.

This will order implicit bindings after explicit offsets.

CGHLSLOffsetInfo CGHLSLOffsetInfo::fromDecl ( const HLSLBufferDecl & BufDecl )

static

Iterates over all declarations in the HLSL buffer and based on the packoffset or register(c#) annotations it fills outs the Offsets vector with the user-specified layout offsets.

The buffer offsets can be specified 2 ways: 1. declarations in cbuffer {} block can have a packoffset annotation (translates to HLSLPackOffsetAttr) 2. default constant buffer declarations at global scope can have register(c#) annotations (translates to HLSLResourceBindingAttr with RegisterType::C) It is not guaranteed that all declarations in a buffer have an annotation. For those where it is not specified a ~0U value is added to the Offsets vector. In the final layout these declarations will be placed at the end of the HLSL buffer after all of the elements with specified offset.
