22 // reloc_pcrel_bx - PC relative relocation, for the b or bl instructions.
25 // reloc_absolute_high - Absolute relocation, for the loadhi instruction
26 // (which is really addis). Add the high 16-bits of the specified global
27 // address into the low 16-bits of the instruction.
30 // reloc_absolute_low - Absolute relocation, for the la instruction (which
31 // is really an addi). Add the low 16-bits of teh specified global
32 // address into the low 16-bits of the instruction.
35 // reloc_absolute_ptr_high - Absolute relocation for references to lazy
36 // pointer stubs. In this case, the relocated instruction should be
37 // relocated to point to a POINTER to the indicated global. The low-16
38 // bits of the instruction are rewritten with the high 16-bits of the
39 // address of the pointer.
