[PATCH v5 0/4] MR636: vkd3d-shader/fx: Add initial support for writing buffers descriptions.
-- v5: vkd3d-shader/fx: Do not align structured data section. vkd3d-shader/fx: Add initial support for writing buffers descriptions. vkd3d-shader/fx: Do not align strings for fx_4/fx_5 profiles. vkd3d-shader/fx: Use variable pointer in write_group().
From: Nikolay Sivov nsivov@codeweavers.com
The helper will need to access group annotations later, and these are available for variables.

Couldn't bytecode_put_bytes() just call bytecode_align() and then call bytecode_put_bytes_unaligned()? Then we only need two functions instead of three.
This is done now.

I see now why additional field was easier - 'size' is set later on, that involves extern_vars which is not populated initially, and that depends on uniform_copy() which, if separated, depends on entry point presence. Still, it's better to use the same field everywhere, I'll see how I can separate this in a way that makes sense. E.g. there is no need to handle function parameters for effects, I don't think it's possible to use them there, and have $Params block written out as a result.
I pushed something for this. It does introduce some duplication. To avoid it, _emit() has to change to set buffer "size" and update variable offsets without adding <temp> variables.
Do we really want to be defining a type rbtree like this? The existing code is explicitly set up to be usable by the backend in such a way—cf. the "bytecode_offset" member—and sm4 types (and I think also sm1) are similarly supposed to be deduplicated, we just don't because it doesn't actually matter.
I'm not sure the answer is "no", mind. There's something to be said for orthogonality, and if we're going to be shoving things through vsir then we should maybe try to avoid hlsl leaking through so much. [Although on the other hand, if we're shoving things through vsir then how *do* we build reflection data? That's an unsolved question.] But I'm not sure the answer is yes either.
Either way, do we really want it to be an rbtree? It doesn't seem likely we'll have enough types to matter, and rbtrees are broadly just more work to deal with than an array or list.

I don't see your point. Why not have it as an rbtree? We have it like that for the compiler. There is one compare function, init/destroy, and that's it. Regarding duplicated types, what I want is a matching binary, because it's much easier to compare this way. There should be no problem of getting it to match in metadata parts, shaders will obviously differ.

I'm not saying it's a lot more work, but it's still a bit more work. You have to define two callbacks, for instance, which you don't have to do with a simpler data structure. I don't think it's wrong to say that *any* use of a more complex data structure in place of a simpler one deserves justification.
The compiler uses an rbtree, but well, it was like that when I got here. The compiler also defines a lot more builtin types, and even then I'm not sure it's enough that an rbtree is *actually* an improvement.

No problem in switching to a list, on my side. For strings it's normally a larger number of elements, because every type name, string constant, and variable name is there, but also not necessarily relevant for performance reasons, until we have actual numbers.

Trees are also used for parameters in d3dx9 effects, and for types in d3d10 ones, so I didn't think twice.
