Re: [PATCH 0/1] MR501: vkd3d-shader/dxil: Set the result register data type for nop casts.

Oh, right, I got confused.
> Minimum precision is a bit messy in DXIL. While FXC emits 32-bit types and flags them as only requiring 16 bits of precision, DXC emits them as 16-bit which are allowed to be implemented as 32-bit. Transparently remapping them is apparently acceptable. We must remap them in SPIR-V since they work much the same there as in TPF.

Ok, thanks for the explanation.
