There is as yet no official documentation.  (IBM does have a project
in progress to write a powerpc32 ABI that describes the current gcc
extensions, but it is only just starting.)  Using the terminology in
"SYSTEM V APPLICATION BINARY INTERFACE PowerPC Processor Supplement"
(google for it if you don't have it), extend table 4-8 with the
following.

Name		Value Field	Calculation
R_PPC_REL16	249   half16	S + A - P
R_PPC_REL16_LO	250   half16	#lo(S + A - P)
R_PPC_REL16_HI	251   half16	#hi(S + A - P)
R_PPC_REL16_HA	252   half16	#ha(S + A - P)
