!
! A simple copy routine that copies 32 bytes using physical
! addresses. Used by drmach_copy_rename() to copy permanent
! memory. Assumes domain is quiesced and addresses are
! aligned appropriately.
!
! Derived from Starfire DR 2.6 version of bcopy32_il.
!
! NOTE: The rdpr instruction executes as a noop. It has no
! runtime value or purpose. It exists here solely for its
! magical property that protects bcopy32_il from the
! actions of Sun Pro's code generator. The ldxa instructions
! used in this inline are not supported by the inline feature
! of the Sun Pro 5.0 product. See inline(1) for details.
! Without the rdpr, the code generator improperly rewrites
! the instructions and emits a misrepresentation of the logic.
