+/* 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. */
