In some scenarios this resource load is NULL, and we are still doing
&load->node on it.
vkd3d/libs/vkd3d-shader/hlsl.c:2195:12: runtime error: member access
within null pointer of type 'struct hlsl_ir_resource_load'
This happens in tests/hlsl/sampler-state.shader_test, in the following
test:
[pixel shader fail]
Texture2D tex;
float4 main(): sv_target
{
return tex.Sample(sampler_state {}, float2(0, 0));
}
Instead of an int3.
Gather operations expect an offset with only two components.
Currently the following field (which is the gather channel) is
parsed as a third component, which leads to wrong and invalid
results.
This fixes a crash on a shader from WRC Generations.
The validator checks that on normalized vsir I/O destination write masks
are always a subset of the element's write mask.
This is currently not always happening for FOG and PSIZE outputs, because
d3dbc input might use the 0xf mask instead, despite these semantics being
scalar.
Note that this problem is hidden when using varying mapping, because in
that case the vsir_program_remap_output_signature() pass, specifically
the remove_unread_output_components() function, fixes the write mask.
This fixes the assertion error
"sm4_generate_vsir_instr_expr Failed assertion: dst_type->e.numeric.type == HLSL_TYPE_BOOL"
which occurs when compiling the following HLSL shader using the ps_4_0 target profile:
uniform float4 x;
uniform bool b;
float4 main() : SV_Target
{
if (!b)
clip(x.x);
else
clip(x.y);
return x;
}
