[vector] x86: Revisit implementation limitations

    Details

    • Type: Enhancement
    • Status: Open
    • Priority: P3
    • Resolution: Unresolved
    • Affects Version/s: repo-panama
    • Fix Version/s: repo-panama
    • Component/s: hotspot

      Description

      Matcher::match_rule_supported_vector() contains current implementation limitations:
        http://hg.openjdk.java.net/panama/dev/annotate/3b869865b8ed/src/hotspot/cpu/x86/x86.ad#l1474

      They should be revisited to ensure there are no "holes" left in back end support. Such "holes" manifest as non-intrinsified operations on some particular hardware.
