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

Signed bitwise left shift. Widening. The bit count by which to shift is an unsigned number. The higher order bits get sign extended in the widening.


shiftlsw(s x, bit bits) → s r0

operands: like Widening xx:2x


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

shiftlsw(s x, n bits) → s r0

operands: like Widening xx:2x


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