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

native on: Tin Copper Gold

Gets the carry/borrow flag or condition code of the ganged operation and puts it on the belt.
This is always available for condition code producing operations, regardless of overflow behavior.

related operations: eql, neq, gtr, geq, lss, leq, overflow, fault

carry() → op r0

operands: like Identity [xx:x]   native on: Copper Tin Gold


encoding: carry(op op0)

Core In Slots Latencies
Tin E1
Copper E1
Gold E1

carry(op op0) → op r0

operands: like Identity [xx:x]   native on: none


encoding: carry(op op0)

Core In Slots Latencies
Tin
Copper
Gold
