speculable  exu stream  exu block  compute phase   operation   in the signed integer value domain  

native on: all

Signed integer lesser than or equal comparison. All comparison operation produce 0 or 1 values of the operand width.

leqs() → s r0

operands: like Identity [xx:x]


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

leqs(s x, s y) → s r0

operands: like Identity [xx:x]

This is an alias for `geqs`, since only the operands need to be swapped.
