40 | /* In order to gain some understanding of code in this file without |
41 | knowing all the intricate details of the linker, note the | |
42 | following: | |
43 | ||
44 | Functions named elf32_hppa_* are called by external routines, other | |
45 | functions are only called locally. elf32_hppa_* functions appear | |
46 | in this file more or less in the order in which they are called | |
47 | from external routines. eg. elf32_hppa_check_relocs is called | |
48 | early in the link process, elf32_hppa_finish_dynamic_sections is | |
49 | one of the last functions. */ | |

edd21aca | 51 | /* We use two hash tables to hold information for linking PA ELF objects. |
252b5132 RH |
52 | |
53 | The first is the elf32_hppa_link_hash_table which is derived | |
54 | from the standard ELF linker hash table. We use this as a place to | |
55 | attach other hash tables and static information. | |
56 | ||
57 | The second is the stub hash table which is derived from the | |
58 | base BFD hash table. The stub hash table holds the information | |
30667bf3 AM |
59 | necessary to build the linker stubs during a link. |
60 | ||
61 | There are a number of different stubs generated by the linker. | |
62 | ||
63 | Long branch stub: | |
64 | : ldil LR'X,%r1 | |

1401 | /* If we are creating a shared library then we need to copy | |
1402 | the reloc into the shared library. However, if we are | |
1403 | linking with -Bsymbolic, we need only copy absolute | |
1404 | relocs or relocs against symbols that are not defined in | |
1405 | an object we are including in the link. PC- or DP- or | |
1406 | DLT-relative relocs against any local sym or global sym | |
1407 | with DEF_REGULAR set, can be discarded. At this point we | |
1408 | have not seen all the input files, so it is possible that | |
1409 | DEF_REGULAR is not set now but will be set later (it is | |
1410 | never cleared). We account for that possibility below by | |
98ceb8ce | 1411 | storing information in the dyn_relocs field of the |
30667bf3 AM |
1412 | hash table entry. |
1413 | ||
1414 | A similar situation to the -Bsymbolic case occurs when | |
1415 | creating shared libraries and symbol visibility changes | |
1416 | render the symbol local. | |
1417 | ||
1418 | As it turns out, all the relocs we will be creating here | |
1419 | are absolute, so we cannot remove them on -Bsymbolic | |
1420 | links or visibility changes anyway. A STUB_REL reloc | |
1421 | is absolute too, as in that case it is the reloc in the | |
1422 | stub we will be creating, rather than copying the PCREL | |
56882138 AM |
1423 | reloc in the branch. |
1424 | ||
1425 | If on the other hand, we are creating an executable, we | |
1426 | may need to keep relocations for symbols satisfied by a | |
1427 | dynamic library if we manage to avoid copy relocs for the | |
