shiftlsw

realizing  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.
