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

edd21aca 53/* We use two hash tables to hold information for linking PA ELF objects.

54
55 The first is the elf32_hppa_link_hash_table which is derived
56 from the standard ELF linker hash table. We use this as a place to
57 attach other hash tables and static information.
58
59 The second is the stub hash table which is derived from the
60 base BFD hash table. The stub hash table holds the information

61 necessary to build the linker stubs during a link.
62
63 There are a number of different stubs generated by the linker.
