New subject: [PATCH vkd3d v2 4/4] vkd3d-shader: Import the HLSL compiler from Wine.

This corresponds to Wine commit 9f9fec18799bf59df6211b7294f8d338caa7f4db.

Note that for the moment, compilation messages have not been ported.

I haven't reviewed the patch line-by-line, although the contents look pretty familiar (including some questionable comments :D). BTW I suspect some of those implicit type conversions might not be correct anymore in newer shader models.

At any rate, this should be as good a starting point as any. The only high-level point I have is that it's a bit unfortunate to introduce a non-reentrant parser now, but it should be possible to fix that afterwards with somewhat contained modifications (and FWIW, reducing the number of changes compared to the version currently in Wine to the bare minimum is a good enough reason for keeping it IMHO).

Yes, that was largely my reasoning. I already have patches queued to convert the parser to be reëntrant, and I think they're not that painful.

I can see the advantage of making it prettier before moving it, but I also figured it made more sense to try to have as much of the history as possible on the vkd3d side.

...

I have one specific comment:

...
+/* The general IR structure is inspired by Mesa GLSL hir, even though the code

ends up being quite different in practice. Anyway, here comes the relevant

licensing information.

FWIW, this was quite true at the time, but it's becoming less and less relevant. The current IR is much closer to e.g. SPIR-V than GLSL HIR and in particular, with the change to a flat IR, the way of manipulating the IR is also entirely different compared to Mesa GLSL HIR and related code. Probably the only "heritage" is some of the naming.

So I don't think the copyright blurb has much of a reason to be there anymore. That said, I don't think carrying the hunk over is a problem, or a big deal anyway.

Sure. It probably deserves a separate patch to remove it anyway.

(and I don't exactly want to be the one to touch copyright notices...)

Should those have an @$(MKDIR_P) as well?

That's fine, but you should probably handle the new shader types introduced by this patch in shader_get_type_prefix().

Thanks for catching those; resent with both fixed.
