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. | |

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 | |
