+Miscellaneous primitive operations on HsInt64 and HsWord64s.
+N.B. These are not primops!
+
+Instead of going the normal (boring) route of making the list
+of primitive operations even longer to cope with operations
+over 64-bit entities, we implement them instead 'out-of-line'.
+
+The primitive ops get their own routine (in C) that implements
+the operation, requiring the caller to _ccall_ out. This has
+performance implications of course, but we currently don't
+expect intensive use of either Int64 or Word64 types.
+
+The exceptions to the rule are primops that cast to and from
+64-bit entities (these are defined in PrimOps.h)
