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

edd21aca | 49 | /* We use two hash tables to hold information for linking PA ELF objects. |
252b5132 RH |
50 | |
51 | The first is the elf32_hppa_link_hash_table which is derived | |
52 | from the standard ELF linker hash table. We use this as a place to | |
53 | attach other hash tables and static information. | |

55 | The second is the stub hash table which is derived from the | |
56 | base BFD hash table. The stub hash table holds the information | |

57 | necessary to build the linker stubs during a link. |
58 | ||
59 | There are a number of different stubs generated by the linker. | |

62 | : ldil LR'X,%r1 | |
