  * notes:
  * - tcache, block descriptor, link buffer overflows result in sh2_translate()
  *   failure, followed by full tcache invalidation for that region
- * - jumps between blocks are tracked for SMC handling (in block_links[])
+ * - jumps between blocks are tracked for SMC handling (in block_links[]),

+ * implemented:
+ * - static register allocation
