JDK-8282221 - x86 intrinsics for divideUnsigned and remainderUnsigned methods in java.lang.Integer and java.lang.Long
Description
Optimized x86 intrinsics for unsigned division and modulus operations are already implemented in JDK-8282221. They can be further optimized for the special case of division by constants and powers of 2 but this is not yet implemented in JDK-8282221. The goal of this enhancement is to implement the above mentioned optimization.
