472 The code for position independent PLT entries looks like this:
474 r12 holds addr of the current GOT at entry to the PLT
476 The GOT holds the address in the PLT to be executed.
479 28(15) = Offset into rela.plt
494 BRC 15,-x # 4 bytes Jump to start of PLT
497 .long ? # 4 bytes offset into rela.plt
499 This was the general case. There are two additional, optimizes PLT
507 L 1,14(1) # 4 bytes Load offset in rela.plt in r1
508 BRC 15,-x # 4 bytes Jump to start of PLT
510 .long ? # 4 bytes offset into rela.plt
