speculable exu stream exu block compute phase operation in the signed fixed point value domain that produces condition codes and rounds to nearest, ties toward even adjacent value
native on: all
Signed fixed point shift right. Rounds towards nearest even. When shifting fixed point values to the right the least significant bit can be treated differently according to the same different rounding strategies that apply to floating point values as well.
shiftrsfe(sf x, bit bits) → sf r0
operands: like Shift [xi:x]
