Missing intrinsics for Integer and Long operations

XMLWordPrintable

      In Long and Integer, the implementations of the following methods are generic, but could be improved for scalar and/or vector code, in a platform-dependent manner:

      reverse (bitwise reversal - RBIT on ARM64, table lookup on x86)
      rotateLeft, rotateRight (instruction if available)

      JDK-8283894 covers the following, which as of 2022 have been added and which should also be made intrinsics:

      compress / expand (x86 PEXT/PDEP)
