intriguing.

i never thought i would say this, it sounds like compilers could
benefit from functional programming.  the tree inference set by
inductive rules.

in XDC2020 a new AMD GPU RADV compiler is being developed.  they just
had to extend the register allocator to bytelevel in order to fully
recognise the SIMD nature of AMDGPU.

we will need that for SV because of the bytelevel typecasting.  a 64
bit register therefore would need 8 bits in the register allocator map
to be set.
