+/* Relocations for function calls must be accompanied by parameter
+   relocation bits.  These bits describe exactly where the caller has
+   placed the function's arguments and where it expects to find a return
+   value.
+
+   Both ELF and SOM encode this information within the addend field
+   of the call relocation.  (Note this could break very badly if one
+   was to make a call like bl foo + 0x12345678).
+
+   The high order 10 bits contain parameter relocation information,
+   the low order 22 bits contain the constant offset.  */
