19 // Hack to rid us of a PPC pre-processor symbol which is erroneously
20 // defined in a PowerPC header file (bug in Linux/PPC)
28 // reloc_pcrel_bx - PC relative relocation, for the b or bl instructions.
31 // reloc_absolute_high - Absolute relocation, for the loadhi instruction
32 // (which is really addis). Add the high 16-bits of the specified global
33 // address into the low 16-bits of the instruction.
36 // reloc_absolute_low - Absolute relocation, for the la instruction (which
37 // is really an addi). Add the low 16-bits of the specified global
38 // address into the low 16-bits of the instruction.
41 // reloc_absolute_low_ix - Absolute relocation for the 64-bit load/store
42 // instruction which have two implicit zero bits.
43 reloc_absolute_low_ix,
45 // reloc_absolute_ptr_high - Absolute relocation for references to lazy
46 // pointer stubs. In this case, the relocated instruction should be
47 // relocated to point to a POINTER to the indicated global. The low-16
48 // bits of the instruction are rewritten with the high 16-bits of the
49 // address of the pointer.
50 reloc_absolute_ptr_high,
52 // reloc_absolute_ptr_low - Absolute relocation for references to lazy
53 // pointer stubs. In this case, the relocated instruction should be
54 // relocated to point to a POINTER to the indicated global. The low-16
55 // bits of the instruction are rewritten with the low 16-bits of the
56 // address of the pointer.
