Giovanni Mascellani (@giomasce) commented about libs/vkd3d-shader/hlsl.h:
- /* Single instruction node of data type uint used to represent the register offset (in register
* components, within the pertaining regset), from the start of the variable, of the part
* referenced.
* The path is lowered to this single offset -- whose value may vary between SM1 and SM4 --
* before writing the bytecode.
- /* Before writing the bytecode, deref paths are lowered into an offset (within the pertaining
* regset) from the start of the variable, to the part of the variable that is referenced.
* This offset is stored using two fields, one for a variable part and other for a constant
* part, which are added together:
* - offset: An offset given by an instruction node, in number of register components.
struct hlsl_src offset;* - offset_const: A constant number of register components. * Since the type information cannot longer be retrieved from the offset alone, the type is * stored in the data_type field. */
- unsigned int offset_const;
Some bike shedding: `const_offset` sounds better to me, since I perceive `const` as an adjective.
