merge

speculable  exu stream  exu block  compute phase   operation   in the logical value domain  

native on: all

Bitwise merge.

It works like a multiplex: the bits in the mask operand decide whether the corresponding bit of the result is taken from op0 or op1.
Or explained differently: it does what pick does on the operand level on the bit level.

---

merge(op op0) → op r0

operands: like Identity [xx:x]

merge(u mask, u bits0, u bits1) → op r0
