speculable  exu stream  exu block  compute phase   operation   in the signed integer value domain   using widening overflow behavior   that produces condition codes

native on: all

Widening signed integer subtraction. When a result value overflows, it is widened.

subsw(s x, s y) → s r0

operands: like Widening xx:2x


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

subsw(s x, imm y) → s r0

operands: like Widening xx:2x


Core In Slots Latencies
