[PATCH v13 0/6] MR514: tests: Use the vulkan runner to run SM1 compilation tests.

[Francisco Casas (＠fcasas)]

Recap:

My previous proposals to extend the shader_runner to SM1 were focusing on separating compilation tests ([shader] directives) from execution tests ([test] directives), and let the generic shader_runner.c:compile_shader() in charge of the former.

However, Henri was more inclined to aim for making the parser agnostic to the language of the tests so we can potentially extend the shader_runner tests to other languages such as d3d-asm. This means, removing the burden of compilation from the parser altogether, and moving it to the runners, probably through a runner->compile function pointer (even if most of them end up doing the same thing, compiling with vkd3d-shader or the native compiler, depending on availability). 

Agreeing with going in this general direction, this MR contains patches to do SM1 compilation calling run_shader_tests() for SM1 profiles from the Vulkan runner (skipping execution for now), and some improvements to the qualifiers syntax.

Despite this, there are parallel discussions on:
- Whether to name the shader models individually in the [require] directives or expressing the range of shader models where the test should pass. In the latter case, whether to run for all shader models, only the lowest one in the SM1, SM4, and SM6 groups, or to allow the runner to select a shader model within the range (I feel strongly against this now, I think the runner should just retrieve a boolean in runner->check_requirements). 
- Where to do the iteration across different shader models, if in run_shader_tests() or expect each runner to call run_shader_tests() several times as we do now.
But there is no need to settle on something for these yet.

---

Now, what may be the most noisy part of this MR is that even though we are calling run_shader_tests() through the Vulkan runner, this will result in calling shader_runner.c:compile_shader() instead of shader_runner_vulkan.c:compile_shader(), but if we follow the "making the parser agnostic" plan, we eventually should get rid of shader_runner.c:compile_shader() and introduce the runner->compile pointer instead.

[PATCH v13 1/6] vkd3d-shader: Make *src and *dst mutable in vkd3d_shader_instruction.

[Giovanni Mascellani]

From: Giovanni Mascellani <gmascellani(a)codeweavers.com>

They were originally made const because no optimization/normalization
pass existed. Now having to cast away const all the time is becoming
more and more burdening.

[PATCH v13 2/6] tests/shader-runner: Support reading multiple model range args for qualifiers.

[Francisco Casas]

From: Francisco Casas <fcasas(a)codeweavers.com>

We can now pass (sm<4) and (sm>=4) to "fail" and "todo" qualifiers, and
we can use multiple of these qualifier arguments using "&" for AND and
"|" for OR.

examples:
todo(sm>=4 & sm<6)
todo(sm<4 | sm>6)

parenthesis are not supported.

Adding additional model ranges for the tests, if we need them, should be
easier now, since they only have to be added to the "valid_args" array.

[PATCH v13 3/6] tests/shader-runner: Call each runner only once.

[Francisco Casas]

From: Francisco Casas <fcasas(a)codeweavers.com>

If the runners require multiple calls to run_shader_tests() for
different shader model ranges, these are moved inside the sole runner
call.

For the same reason, the trace() messages are also moved inside the
runner calls.

[PATCH v13 4/6] vkd3d-shader/d3dbc: Emit fixme for HLSL_RESOURCE_SAMPLE_LOD.

[Francisco Casas]

From: Francisco Casas <fcasas(a)codeweavers.com>

Currently, HLSL_RESOURCE_SAMPLE_LOD is not implemented for d3dbc,
but we are incorrectly writting a texld instruction to handle it.
This causes SM1 tests with the vulkan backend (in following patches)
to fail if VKD3D_SHADER_CONFIG="force_validation" is enabled.

For now a fixme is emited in these cases.

[PATCH v13 6/6] tests: Use the vulkan runner to run SM1 compilation tests.

[Francisco Casas]

From: Francisco Casas <fcasas(a)codeweavers.com>

At the current moment this is a little odd because for SM1 [test]
directives are skipped, and the [shader] directives are not executed by
the shader_runner_vulkan.c:compile_shader() but by the general
shader_runner.c:compile_shader(). So in principle it is a little weird
that we go through the vulkan runner.

But fret not, because in the future we plan to make the parser agnostic
to the language of the tests, so we will get rid of the general
shader_runner.c:compile_shader() function and instead call a
runner->compile_shader() function, defined for each runner. Granted,
most of these may call a generic implementation that uses native
compiler in Windows, and vkd3d-shader on Linux, but it would be more
conceptually correct.

Ideally these would be declared like this:
```c
static const char HLSL_COMPILER[] = "d3dcompiler47.dll";
```

In principle I wouldn't hold the MR for this, particularly since this is shader runner code instead of actual library code, but this MR happens to conflict with one of the other MRs going in today.

On the other hand, perhaps the right thing to do is write the pass like this but then eventually move it from ir.c to d3dbc.c.

The way I see it, this moves it in the right direction; one less place for the backend to have to care about the shader version. You could certainly argue for e.g. setting an appropriate write mask in the parser so that we don't have to care about the shader version here, and I'd be inclined to agree. I don't think that's an argument against this patch as such though.

That makes sense. I'd still prefer it in the parser, I think, but I can see how this is not moving in the wrong direction.
