83851133c5 vkd3d-shader/ir: Set merged signature element interpolation mode only from used elements. 2024-01-18 23:15:27 +01:00
Conor McCarthy
b8280e4210 vkd3d-shader/ir: Revert "Do not merge signature elements which have different interpolation modes.". 
This reverts commit b5c067b41a.

The commit causes regressions in other shaders because unused elements
do not have an interpolation mode.

4c30b23821 vkd3d-shader: Make the control point count the outer dimension of I/O arrays. 
The relative-addressed case in shader_register_normalise_arrayed_addressing()
leaves the control point id in idx[0], while for constant register
indices it is placed in idx[1]. The latter case could be fixed instead,
but placing the control point count in the outer dimension is more
logical.

418e8d8100 vkd3d-shader/ir: Expand index range write masks to cover all element masks. 
For example, this occurred in a shader:

reg_idx write_mask
   0      xyz
   1      xyzw
   2      xyzw
   3      xyz

The dcl_indexrange instruction covered only xyz, so once merged, searching for
xyzw failed.

It is impossible to declare an input array where elements have different
component counts, but the optimiser can create this case. One way for
this to occur is to dynamically index input values via a local array
containing copies of the input values. The optimiser converts this to
dynamically indexed inputs.

b0c8a47f9d vkd3d-shader/ir: Check that SSA registers are used validly. 
Specifically, they are assigned only once and only assigned components
are used.

Right now we don't check that the assignment dominates all usages.

78d95889bd vkd3d-shader: Make *src and *dst mutable in vkd3d_shader_instruction. 
They were originally made const because no optimization/normalization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.

3f52fda8ad vkd3d-shader: Lower shader model 1/2 inter-stage I/O to a flat array. 
An alternative is that we stash the reg_type in the signature, but this seems
far simpler for the backend to deal with.

read_u32().

b5c067b41a vkd3d-shader/ir: Do not merge signature elements which have different interpolation modes. 
Regression in signature normalisation, however the old code was not
correct either because it would apply the interpolation mode to all
components. Found in an Assassin's Creed: Valhalla shader.

b1123ed35f vkd3d-shader/ir: Correctly compute the TEMP count after hull shader flattening. 
The previous computation was incorrect because the count was taken
after resetting it to zero (as part of setting the instruction to NOP).

0a7e200f89 vkd3d-shader/ir: Do not enfore DCL_TEMPS count for hull shaders. 
Hull shaders have a different temps count for each phase, and the
parser only reports the count for the patch constant phase.
In order to properly check for temps count on hull shaders, we first
need to decode its phases.

b73d2c978d vkd3d-shader/ir: Check for vocp usage during IR normalization. 
The hull shader barrier used for this was broken by I/O normalization, since
vocp is no longer exposed to the spirv backend.

Restore this barrier by checking for vocp during normalization instead.
