speculable  exu stream  exu block  compute phase   operation   in the logical value domain   that produces condition codes

aliases: muls mulu muls2 mulu2
native on: all

Integer multiplication. Multiplication resides in its own type of Functional Unit separate from most other interger operations.

mul(op x, op y) → op r0

operands: like Identity [xx:x]
