    S390: Optimize allocate sequence · 0ddb3645
    joransiu authored
    Improve the S390 allocate sequence by:
    - Keeping allocation limit in memory, and leverage compare RX-instr.
    - Prefetching subsequent cache lines from allocation top.
    - Optimizing object tagging with LA
    - Optimizing increment for Fast-Allocate with ASI/AGSI
