Shenandoah: SBSA::load_at() should save/restore registers when calling SATB barrier

    XMLWordPrintable

    Details

    • Subcomponent:
      gc

      Description

      This appears to be the root cause of intermittent failures with concurrent GC with concurrent class unloading on(x86_64 and x86_32).

      Registers should be saved and restored for calling shenandoah_write_barrier_pre(), which can mess up the registers, especially, on slow path.
