Shader Model 6 introduces a 16-bit float (half) type, and 16-bit and 64-bit integer types. Storing extra info in the type enum simplifies checking if a type is any integer, floating point or numeric type, and the declaration of SPIR-V types. The benefits depend on using enum vkd3d_data_type in the backend instead of vkd3d_shader_component_type.
Patch 2 is difficult to split because types typically flow through to vkd3d_spirv_get_type_id(), so partial changes would require new calls to conversion functions which would be deleted again later.

What D3DKMTPresent() does is that it sends a command to the compositor/DWM to display contents. Since DWM is responsible for drawing the window decoration, it allows the nonclient decorations to be overwritten without affecting window styles. The complexity here is that we don't have a DWM. Implementing a DWM and making it work with the host WM is not trivial, if not impossible. Also, the window decoration is currently handled by the host system, for example, Mutter. Having D3DKMTPresent() is certainly more architecturally correct. That way, DWM can intercept these surfaces and do the composition without tearing and not worry about the surface lifetime.

This is obviously questionable, as it requires reaching into Wine internals in
tests (beyond simply detecting whether Wine is in use).
However, we are at a point where, for d3d10 and above, the Vulkan renderer works
well enough in general to see real use [in fact, in my experience it usually
works better than the GL renderer], and at this point I think avoiding
regressions is quite important. It is currently difficult to run tests with it
when the results contain so much noise, and I think we need to solve this
problem, by actually marking which tests work on each backend.
We could in theory expose the renderer through some adapter string, but I
believe in the past applications have been sensitive about the contents of
adapter strings.
Fixing either renderer to reach and maintain parity is not feasible. The GL
renderer is not going away, but regrettably GL as an API is abandoned by
Khronos, and important features we need in order to implement some Direct3D
features will probably never be introduced into GL. Moreover, the amount of
effort that would be required to reach parity is not small, and itself would all
need to be verified manually.

Sounds great :-)
The "fullscreen window styles" problem (and one of the older d3d contributors can correct me on this) is basically that some applications use ddraw (and other versions?) to present to a fullscreen window, expecting the presented area to cover the whole screen, but wgl (and Vulkan) swapchains only present to the client rect. We currently get around this by changing the window styles to remove all the nonclient decorations, but that breaks some applications too. What we want is a way to present to the actual window, and part of the idea is that using D3DKMTPresent() is the architecturally correct way to do this.
I don't quite know what the concerns are for dcomposition either. Zhiyi was looking at that and ran into a wall, but he probably can at least describe the problem in greater detail.
There are also some thoughts about using D3DKMTPresent() to deal more efficiently with some cases where we currently have to do a GDI blit. I'm fuzzy on these details though; again Henri can explain it better.

Sub / Function can be on one line, but only if there's brackets.
```
| Storage_opt tFUNCTION Identifier ArgumentsDecl BodyStatements tEND tFUNCTION
```
This leads to sometimes to `link_statements` being called with `head` being NULL, probably because now the `:` can be parsed as `Statement` in `BodyStatements`.
Also note that this introduces another shift/reduce conflict, could be related, but I don't understand it well enough. Feedback would be appreciated, I'm still learning bison.

I pushed a new implementation incorporating the changes you're suggesting, and honestly I don't dislike it: https://gitlab.winehq.org/giomasce/wine/-/commits/chianti (only the last three commits changed in a meaningful way; or maybe at all). With this implementation it should be relatively easy to present with whatever API is available, though I don't really know how the options you mention work, so maybe there is some additional complexity I'm not aware of.

In a declaration with multiple variables, the variables must be created
before the initializer of the next variable is parsed. This is required
for initializers such as:
```
float a = 1, b = a, c = b + 1;
```
The solution is to parse the type information in the same rule as the first variable ('a' in this case) so that it can be declared before the parser reaches the initializer for the following variables.
To initialize the following variables, the type information is passed along from the first variable's struct parse_variable_def to the next and so on.

We have the other headers but we use them only for the ATL implementation. They are not something we'd want to use globally.
As for a new include/wine helper, there doesn't seem to be enough usage of that function to justify it.

atlbase.h, atlcom.h, and atlwin.h are also C++-only in Windows, but Wine allows them to be used in C and uses them in its own C code. I assumed that the same logic would apply to atlconv.h, but if that doesn't work then we may want to introduce a new helper in include/wine.
