I don't think it needs to convert anything. For integer input it simply should returns it as a result, for floor()/round()/trunc()/ceil(). After that normal cast should happen, resulting in ftoi/itof. Or maybe for integer case it's enough to return cast node to arg type.
By the way, is it possible to get textual output right away, without going through dxbc -> disasm?

As far as I can see it really returns a float4 for an int4 input. This matters, for example, if function overloading is done on the output (and possibly, in edge cases, for very big integers).

What I usually do is enable logging and run some .shader_test that compiles and run that code. It will dump to the log both the IR and the compiled code. Of course is still compilation and disassembling, but you don't have to do it by hand.
OTOH, I think you're not the first one to ask for that thing (hlsl -> d3d_asm directly in vkd3d-compiler), so it might eventually happen.

That looks sensible, except that it should be:
if (type->base_type != HLSL_TYPE_FLOAT && type->base_type != HLSL_TYPE_HALF)
We don't really handle half values so far (and it's not clear how they differ from floats), but at least for typing I guess it makes sense to do the right thing, given that it's easy.
Thanks, Giovanni.

The way you tested with overloaded functions, half is handled the same as int.

I suppose that's an improvement in the sense that it should work in practice for most of our existing tests, but it doesn't strike me as entirely correct either. In particular, the restriction is that we can't destroy the state object until all command lists referencing it have finished executing on the GPU. That mostly works out in practice because the typical pattern is to do a "draw", followed by a "probe", in which case the "probe" will wait for the command list to finish executing, but I could certainly imagine writing tests where we do multiple draws before probing.

Would it be correct in terms of test results to flush current command list, on repeated "draw"s? I see there is ::Reset() that according to docs will reinitialize recording, if last Close() succeeded. Test could use "pso != NULL" as a marker that "probe" wasn't used since last draw, and close-exec-wait-reset right before starting new recording.
Another brute force option is to simply allow for arbitrary number of state objects in test context, accumulated indefinitely until next "probe".

if (!context->c.pso) return;I suppose that's an improvement in the sense that it should work in practice for most of our existing tests, but it doesn't strike me as entirely correct either. In particular, the restriction is that we can't destroy the state object until all command lists referencing it have finished executing on the GPU. That mostly works out in practice because the typical pattern is to do a "draw", followed by a "probe", in which case the "probe" will wait for the command list to finish executing, but I could certainly imagine writing tests where we do multiple draws before probing.
Would it be correct in terms of test results to flush current command list, on repeated "draw"s? I see there is ::Reset() that according to docs will reinitialize recording, if last Close() succeeded.

Right, either of those approaches should work. The latter would likely be a bit more efficient, although I don't think we're overly concerned about the performance of the tests (yet). In case of the first approach, note how get_texture_readback_with_command_list() (used by the "probe" implementation) does this:
- Close the existing command list with ID3D12GraphicsCommandList_Close(). - Execute the command list with exec_command_list(). - Wait for the queue to become idle with wait_queue_idle().
We then call reset_command_list() to restart recording.
