Overview of Abortable areas

Abortable dynamic areas are dynamic areas which are able to handle data/prefetch aborts in the same way as OS_AbortTrap. When an abort within the extent of the dynamic area, the Dynamic Area AbortTrap handler will be invoked in order to let the DA handle the abort.

Internally, the OS registers an AbortTrap handler which covers the logical address range of the dynamic area, and forwards AbortTrap requests on to the dynamic area handler.

Additionally, OS_Memory 24 will report address ranges covered by abortable dynamic areas as being “abortable”; this does not currently happen for basic OS_AbortTrap regions.
