[PATCH v4 0/6] MR553: Draft: vkd3d-shader/d3d-asm: Dump the input and output signatures.
At some point I would like to have an assembler for TPF, so that it's easier to write and modify tests. This is a first step in that direction, fixing some kind of format for serializing signatures in the comment at the beginning of the assembler code. I'm not decided yet on all details, so take this as an RFC for the moment. -- v4: tests: Test emitting the signature. vkd3d-compiler: Add an option to emit the signature when disassembling. vkd3d-shader/d3d-asm: Support emitting the shader signature. vkd3d-shader/d3d-asm: Refactor dumping a write mask to a dedicated function. vkd3d-shader/d3d-asm: Describe the ASM dialect with a bunch of flags instead of a plain enum. vkd3d-shader/d3d-asm: Do not make a copy of the buffer before returning it. https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/553

I think I like the syntax as it is, at least I agree with the changes that have been made, but: * Do we really want to invent a new set of names like that for sysval? Should we just clip VKD3D_SHADER_SV from the existing enum instead? * What's the plan for GS stream index and for minimum precision? * Any reason we're leaving out patch constant signatures from this series?

This feels weird, partly because it's in dump_signatures(), also because I don't see why it's SHEX and not SHDR. -- https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/553#note_58214
Do we really want to invent a new set of names like that for sysval? Should we just clip VKD3D_SHADER_SV from the existing enum instead?
I copied them from native `/dumpbin`. We might still want to use our existing enum, sure; my personal opinion is that it's nice to have them a bit shorter.
What's the plan for GS stream index and for minimum precision?
The general idea is that unspecified fields are treated as default; so we have to dump fields until all the rightmost ones are default. I was aware of minimum precision, but not of GS stream index. I'll try to add support for both.
Any reason we're leaving out patch constant signatures from this series?
No, it's just that I still have to add support for this too. My knowledge of shader signatures is still pretty young, so I'm learning while I'm doing.

Ok, I can move this out. WRT to using fourccs, I don't have strong opinions, but I'd like to avoid overcomplicating the matter. So, for example, I would try to avoid two different tags depending on whether we're using minimum precision or not. My idea is that the directives I'm introducing specify the logical data; it's up to the assembler to decide which tags to use depending on the data. Using this point of view it might be preferable to rather use: ``` .section input .section output .section patch_constant .section code ``` However Henri explicitly suggested using fourccs, so he might have opinions here. -- https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/553#note_58224

Ah, I should have recognized that. If there's precedent I think that's fine, I just thought we were inventing names out of nowhere.

Fair enough. FWIW, patch constant signatures are pretty simple: they're output for HS and input for DS. I think you can just copy any one of the tessellation shader pairs from d3d12.c for a simple example.

Hrm, I see those were in the original suggestion. What's weird about it is mostly that SHEX is the extended 5.0 version of SHDR, whereas ISGN and OSGN are the original versions. Granted, that *is* the default you get with 5.0, if you don't have minimum precision or GS stream index, but it feels like not the most obvious arbitrary choice. -- https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/553#note_58248
The idea was mostly that you would then be able to specify the contents of arbitrary DXBC sections with things like .byte and .string. That doesn't have to be mutually exclusive with something like .input/.output/.patch_constant/.text, of course, and we could certainly start with those. -- https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/553#note_58445
