amd64 vm should not crash on em64t

    Details

    • Subcomponent:
    • Resolved In Build:
      01
    • CPU:
      x86, itanium
    • OS:
      generic, linux, linux_redhat_3.0

      Description

      The amd64 vm, like the x86 vms, emits slightly different code depending
      on the features supported by the platform it's running on. This is ok,
      but we shouldn't unconditionally generate opteron-only code (in the
      form of prefetchw) w/o checking. We currently do this in the inner
      gc loops when invoking Prefetch::write, causing illegal instruction
      faults on em64t.
