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

aliases: shiftlss2
native on: all

Signed bitwise left shift. Saturating. The bit count by which to shift is an unsigned number. When a one gets moved out, the result is the smallest negative number for the width.
When the highest order bit changes from zero to one, the result is the highest positive number for the width.


shiftlss(s x, bit bits) → s r0

operands: like Shift [xi:x]
