[PATCH v2 0/7] MR744: vkd3d-shader/hlsl: Improve SM1 support for non-float operations, part 5.
-- v2: vkd3d-shader/hlsl: Use LOGIC_AND instead of MUL in all(). vkd3d-shader/hlsl: Use LOGIC_OR instead of BIT_OR in any(). vkd3d-shader/ir: Add missing src swizzle in vsir_program_lower_texkills(). tests: Add failing test for clip.shader_test in SM1.
From: Francisco Casas fcasas@codeweavers.com

Actually, more importantly, texkill _does_ operate on all four components for 2.0, and for 1.x it has very restricted usage anyway (you can't use it on arbitrary expressions). Not sure why the test is failing in that case...
You are totally right, there is a reason why the test is failing. Currently we are failing to translate texkill to spir-v correctly, it is just taking the first component into account. I missed setting up a src swizzle in vsir_program_lower_texkills().
For some reason I thought that the reason why the test was failing in native was because texkill only considered the first 3 components, but this was a ir.c problem.
I replaced the patch that introduced JUMP_TEXKILL.

So, integers and bools are represented internally as float in SM1, so a reinterpret has no real effect (doesn't emit any instruction) besides avoiding the "SM1 non-float expression" fixme in d3dbc.
I think that emitting this fixme is correct for ABS and NEG operations on bool types, and thus, the reinterpret should be explicit in HLSL IR.
lower_nonfloat_exprs() should be taking care of that fixme.

Thinking about it better, I think that the problem is not that we don't have a way to write ABS and NEG operations on bool types in d3dbc.c, but that those operations should not be generated at all in well-formed HLSL IR, because they make sense for integers and floats but not bool.
It should not be a fixme, but an internal compiler error, despite of the shader model.
So to fix it, the conditional is casted to a float before performing the operations, which is good because a ternary with a float condition is still valid (and in the same function, it gets turned into a CMP anyways).
I see now that I could have used a CAST instead of a REINTERPRET, but I still think that the problem should be solved in lower_ternary() were it is introduced.

Personally I think all these sm1-specific lowering passes are not ideal. I would assert that we should just be translating one instruction into multiple instructions when generating the IR. This is simpler than writing HLSL lowering passes, it avoids the need for some basically backend-specific ops like OP3_CMP, and it reduces the amount of backend-specific logic in the core HLSL compiler, or at least moves it closer to the end.

And for things like enum hlsl_base_type, i.e. float vs int/bool, that means we explicitly handle those, probably on a per-instr/per-expr basis, in write_sm1_instructions().

I think I agree, but I don't see how this is actionable in this MR in particular.
I still have in my backlog to introduce vsir between the HLSL->d3dbc translation. I think it may be preferable to write these transformations in a d3dbc-specific vsir pass, which can gradually start absorbing those currently done in HLSL IR (looking at lower_nonfloat_exprs()), than to translate one IR instruction into multiple bytecode instructions, which requires the scaffolding for using additional temporary registers in some cases.

Mostly just that I don't like to see more lowering code introduced.
What I'd do here is either:
* make the abs/neg conditional on the type being non-bool,
* change pass order or duplicate passes such that lower_nonfloat_exprs() happens after lower_ternary(),
And either:
* always cast to bool when creating HLSL_OP3_TERNARY (which implies getting rid of that abs/neg entirely), or
* assert that HLSL_OP3_TERNARY has an implicit cast to bool, and hence stop casting to bool when we don't need to.

Of course we want that anyway, but to be clear, it doesn't need to block getting rid of these passes either. E.g. what I want it something like the attached diff.
