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

native on: all

Integer equality comparison. All comparison operations produce 0 or 1 values of the operand width.

eql() → op r0

operands: like Identity [xx:x]


Core In Slots Latencies
Tin E0 E1
Copper E0 E1
Silver E0 E1 E2 E3
Gold E0 E1

eql(op x, op y) → op r0

operands: like Identity [xx:x]

Both operands must be the same byte size.

Core In Slots Latencies
Tin E0
Copper E0
Silver E0 E1 E2 E3
Gold E0

eql(op x, imm y) → op r0

operands: like Identity [xx:x]


Core In Slots Latencies
Tin E0
Copper E0
Silver E0 E1 E2 E3
Gold E0

eql(conditioncode) → op r0

operands: like Identity [xx:x]

Gets the inequality condition code of the ganged operation and puts it on the belt.

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

alternate encoding: skinny
