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]
