C2 compiler support for Float16 type and associated scalar operations

XMLWordPrintable

    • Type: Enhancement
    • Resolution: Fixed
    • Priority: P4
    • 25
    • Affects Version/s: 24, 25
    • Component/s: hotspot
    • b10
    • x86_64, aarch64
    • generic

      • Add a new Float16 value-based class encapsulating a short field holding IEEE 754 binary16 encoded value.
      • Float16 type should have operation level parity with the existing Float type.
      • For cleaner interface develop a helper class Float16Math containing intrinsic entry points for various intrinsified Float16 operations.
      • Intrinsic entry points will receive and return unwrapped ‘short values’ holding IEEE 754 binary16 values.
      • Add compiler support encompassing inline-expander, new IR, auto-vectorization, and efficient backend implementation for x86 and AArch64 targets.
      • Develop new functional and performance validation tests covering newly added support.
