Use flags fields for JVMCI specific bool fields in JavaThread

    XMLWordPrintable

Details

    Description

      JDK-8152311 adds an extra JVMCI-specific bool field (i.e., _adjusting_comp_level) to JavaThread. This brings the total number of JVMCI-specific bool fields to 3. Up to 16 bytes could be saved (depending on layout used by C++ compiler) per thread if a byte sized _flags field is used instead for these bool fields.
