Until vkd3d-shader is patched, an atomic op on a typed buffer where
StorageImageReadWithoutFormat is available will cause SPIR-V validation
failure, and assertion in Mesa debug builds, because the image will be
declared with Unknown format.
Otherwise, for instance, the added test results in:
debug_hlsl_writemask: Assertion `!(writemask & ~VKD3DSP_WRITEMASK_ALL)' failed.
Which happens in allocate_variable_temp_register() when the variable's
type reg_size is <= 4 but its component count is larger, which may
happen if it contains objects.
Do not rely on a draw or dispatch command to do this.
This allows more efficiently testing syntax, in cases where testing the actual
shader functionality is not interesting.
Otherwise the test fails on a NVIDIA GeForce GTX 1050 Ti GPU.
The error being:
shader_runner:535:Section [test], line 9: Test failed: Got {2.72165507e-01, 4.08248246e-01, 5.44331014e-01, 6.80413783e-01}, expected {2.72165537e-01, 4.08248305e-01, 5.44331074e-01, 6.80413842e-01} at (0, 0).
This should silence warnings about some branches non returning any value
without requiring additional "return 0" statement or similar.
Also, in theory this might enable to compiler to optimize the program
a little bit more, though that's unlikely to have any measurable effect.
HLSL_ARRAY_ELEMENTS_COUNT_IMPLICIT (zero) is used as a temporal value
for elements_count for implicit size arrays.
This value is replaced by the correct one after parsing the initializer.
In case the implicit array is not initialized correctly, hlsl_error()
is called but the array size is kept at 0. So the rest of the code
must handle these cases.
In shader model 5.1, unlike in 5.0, declaring a multi-dimensional
object-type array with the last dimension implicit results in
an error. This happens even in presence of an initializer.
So, both gen_struct_fields() and declare_vars() first check if the
shader model is 5.1, the array elements are objects, and if there is
at least one implicit array size to handle the whole type as an
unbounded resource array.
