speculable exu stream exu block compute phase operation in the signed integer value domain using excepting overflow behavior that produces condition codes
aliases: shiftlsx2
native on: all
Signed bitwise left shift. Excepting. The bit count by which to shift is an unsigned number. Whenever the new most significant bit is different from the one before, an overflow NaR is produced.
shiftlsx(s x, bit bits) → s r0
operands: like Shift [xi:x]
