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_vanilla - A standard relocation, where the address of the
29 // relocated object completely overwrites the address of the relocation.
32 // reloc_pcrel_bx - PC relative relocation, for the b or bl instructions.
35 // reloc_pcrel_bcx - PC relative relocation, for BLT,BLE,BEQ,BGE,BGT,BNE,
36 // and other bcx instructions.
39 // reloc_absolute_high - Absolute relocation, for the loadhi instruction
40 // (which is really addis). Add the high 16-bits of the specified global
41 // address into the low 16-bits of the instruction.
44 // reloc_absolute_low - Absolute relocation, for the la instruction (which
45 // is really an addi). Add the low 16-bits of the specified global
46 // address into the low 16-bits of the instruction.
49 // reloc_absolute_low_ix - Absolute relocation for the 64-bit load/store
50 // instruction which have two implicit zero bits.
