In
back::spv
:Factor out the numeric variants of
LocalType
into a new enum,NumericType
.Split the
Value
variant intoNumeric
andLocalPointer
variants, and letLocalPointer
point to any numeric type, including matrices.In subsequent PRs, we'll need to spill matrices out into temporary local variables. This means we'll need to generate SPIR-V pointer-to-matrix types, so
LocalType
needs to be able to represent that.Rename
make_local
toLocalType::from_inner
.Change the free function
back::spv::make_local
into an associated functionLocalType::from_inner
.
