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 vector left shift. Widening. The bit count by which to shift is an unsigned number. The higher order bits get sign extended in the widening. Produces two result vectors.


shiftlswv(s x, bit bits) → s r0, s r1

operands: like Widenv XX:2X2X
