/* cacheflush stub
*
* Most hardware platforms on which GT.M is implemented use separate
* instruction and data caches. It is necessary to flush these caches
* whenever we generate code in a data region in order to make sure
* the generated code gets written from the data cache to memory and
* subsequently loaded from memory into the instruction cache.
*
* Input: addr starting address of region to flush
* nbytes size, in bytes, of region to flush
* cache_select flag indicating whether to flus
* I-cache, D-cache, or both
*
* This stub is for those platforms that don't use separate data and
* instruction caches.
