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. */

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

61 There are a number of different stubs generated by the linker.

1213 differentiate between the two. As you can imagine, this
1214 is a real pain when it comes to generating code to call
