-- v6: vkd3d-shader/hlsl: Consider duplicated input semantic types equivalent in SM1. vkd3d-shader/hlsl: Handle possibly different types in input semantic var load. vkd3d-shader/hlsl: Error out when a semantic is used with incompatible types. vkd3d-shader/hlsl: Error out when an output semantic is used more than once. vkd3d-shader/hlsl: Support semantics for array types. vkd3d-shader/hlsl: Don't create semantic vars more than once. vkd3d-shader/hlsl: Move get_array_size() and get_array_type() to hlsl.c. tests: Test duplicated semantics. tests: Test array types with semantics. vkd3d-shader/hlsl: Avoid invalid input/output copies for non-numeric types. tests: Allow invalid vertex shader tests. tests: Expect S_OK result on [vertex shader].

The use of the hlsl_semantic.reported_duplicated_output_next_index field allows reporting multiple overlapping indexes, such as in the following vertex shader:
void main(out float1x3 x : OVERLAP0, out float1x3 y : OVERLAP1) { x = float3(1.0, 2.0, 3.2); y = float3(5.0, 6.0, 5.0); }

While at the same time avoiding reporting overalps more than once for large arrays:
struct apple { float2 p : sv_position; };
void main(out apple aps[4]) { }

Now the tests should pass (could you check again @giomasce?), but we still have to address the problem of properly allocating input semantics and see if the shader runner/runtime is replicating the same behavior than native when matching vertex shader output semantics with pixel shader input semantics. I think that's better left for another MR though.
The overlapping semantics tests are failing for me on Windows, with what looks like a leaked internal compiler error code:

Since all the unexpected hrs are on tests that are expected to fail, this just means that the native compiler is retrieving a different error code than E_FAIL for shaders with incompatible input semantics, right?

Yes.
I'm not really sure how to deal with this. Possibly best is to just punt and keep these marked as todo. That said, if you're submitting them I assume they didn't fail for you?

Er, no, that's not enough, because they'll still fail on Windows.
Yeah, this is awkward. It's obviously not great, but I wouldn't mind just inserting something like "if (hr == 0x80010064) hr = E_FAIL" in the shader runner for now. I don't think matching the internal error code is likely to be important.

Okay, I will add the check in the shader_runner.

Yeah. Wherever that HRESULT comes from, it doesn't look it is intended. I agree we can just ignore it.
After mapping the unindentified hr 0x80010064, when I run the shader runner on Windows, this test from `entry-point-semantics.shader_test`:
``` % Arrays (even multi-dimensional) of struct elements are allowed. The fields in the different struct % elements get the same indexes. [pixel shader] struct apple { float4 texcoord : TEXCOORD0; float4 arb : UNUSED; };

I wonder if hr 0x80010064 and this new hr 0x80070057 here are related to duplicated input semantics. I will do more testing, but if that's the case, perhaps we would want a way to tell the shader runner when a shader should compiler but not it is not required to be executed properly.

It is worth noting that to get this output I had to disable stdout and stderr buffering with `setbuf(stdout, NULL)` and `setbuf(stderr, NULL)` in `shader_runner.c`. Otherwise, on Windows, the program is terminated before the buffer is printed.

That's broadly what 4d17758657 was for. It was specifically meant for cases where testing syntax was interesting but testing execution wasn't, but it can work here too.

I doubt that the crash has anything to do with duplicated input semantics, though, since that's not visible in the bytecode at all. Probably more likely is that the unused shader input semantic isn't output by the vertex shader. Just like merge request 159, using sv_position instead would probably work.

The segfault persists even if the field with the `UNUSED` semantic is removed.
It goes away when `TEXCOORD0` is not duplicated though, for instance if we make `apple aps[1][1]`:
```hlsl struct apple { float4 texcoord : TEXCOORD0; float4 arb : UNUSED; };
float4 main(in apple aps[1][1]) : sv_target { return float4(aps[0][0].texcoord.xy, 0, 0); } ````
The segfault persists even if the field with the `UNUSED` semantic is removed.

That doesn't make any sense; the duplication doesn't show up in the bytecode at all. There must be something else going on.

if we make `apple aps[1][1]`: That doesn't make any sense; the duplication doesn't show up in the bytecode at all. There must be something else going on.
Ah, yes, ignore my comment. I got myself really confused here.
Contrary to what I said, it is the `UNUSED` semantic the one that creates the segfault, and when I delete it, the segfault goes away. Yes, there can be a duplicated `TEXCOORD0` input semantic.
