312 | both USE_REL and USE_RELA ['twould be nice if such a critter existed], | |
313 | if only to serve as a learning tool. | |
314 | ||
315 | The RELOCATE_SECTION function is called by the new ELF backend linker | |
316 | to handle the relocations for a section. | |
317 | ||
318 | The relocs are always passed as Rela structures; if the section | |
319 | actually uses Rel structures, the r_addend field will always be | |
320 | zero. | |
321 | ||
322 | This function is responsible for adjusting the section contents as | |
323 | necessary, and (if using Rela relocs and generating a relocatable | |
324 | output file) adjusting the reloc addend as necessary. | |
325 | ||
326 | This function does not have to worry about setting the reloc | |
327 | address or the reloc symbol index. | |
328 | ||
329 | LOCAL_SYMS is a pointer to the swapped in local symbols. | |
330 | ||
331 | LOCAL_SECTIONS is an array giving the section in the input file | |
332 | corresponding to the st_shndx field of each local symbol. | |
333 | ||
334 | The global hash table entry for the global symbols can be found | |
335 | via elf_sym_hashes (input_bfd). | |
336 | ||
337 | When generating relocatable output, this function must handle | |
338 | STB_LOCAL/STT_SECTION symbols specially. The output symbol is | |
339 | going to be the section symbol corresponding to the output | |
340 | section, which means that the addend must be adjusted | |

1494 | to this opcode. The next 8 bits of the addend indicates the | |
1495 | number of bytes in the insn. We use the rest of them | |
1496 | ourselves as flags for the more expensive operations (defines | |
1497 | above). The three relocs are: | |
1498 | ||
1499 | RL_JUMP: This marks all direct jump insns. We check the | |
1500 | displacement and replace them with shorter jumps if | |
1501 | they're in range. We also use this to find JMP.S | |
1502 | insns and manually shorten them when we delete bytes. | |
1503 | We have to decode these insns to figure out what to | |
1504 | do. | |
1505 | ||
1506 | RL_1ADDR: This is a :G or :Q insn, which has a single | |
1507 | "standard" operand. We have to extract the type | |
1508 | field, see if it's a wide displacement, then figure | |
1509 | out if we can replace it with a narrow displacement. | |
1510 | We don't have to decode these insns. | |
1511 | ||
1512 | RL_2ADDR: Similarly, but two "standard" operands. Note that | |
1513 | r_addend may still be 1, as standard operands don't | |
1514 | always have displacements. Gas shouldn't give us one | |
1515 | with zero operands, but since we don't know which one | |
1516 | has the displacement, we check them both anyway. | |
1517 | ||
1518 | These all point to the beginning of the insn itself, not the | |
1519 | operands. | |
1520 | ||
1521 | Note that we only relax one step at a time, relying on the | |
1522 | linker to call us repeatedly. Thus, there is no code for | |
1523 | JMP.A->JMP.B although that will happen in two steps. | |
1524 | Likewise, for 2ADDR relaxes, we do one operand per cycle. | |
