##vector>scalar
Basic block instructions

Prev:	##sub-vector
Next:	##inc

Vocabulary
compiler.cfg.instructions

Class description
This instruction is very similar to ##copy.

dst	destination vreg
src	source vreg
rep	representation for the source vreg

Notes
The two vregs must not necessarily share the same representation.
