- * o INTERNAL_ERROR is never generated by the compiler and usually
- * indicates an error in the heap.
- * PANIC is generated by the compiler whenever it tests an "irrefutable"
+ * o CASEFAIL is generated by the compiler whenever it tests an "irrefutable"
* pattern which fails. If we don't see too many of these, we could
* optimise out the redundant test.
- *
- * o If you add any new instructions, you have to check that each enumeration
- * has at most 256 entries in it --- some of the lists are very close to
- * overflowing.
