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.

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

1172 For executables, the original 32-bit ABI allowed two
1173 different styles of PLABELs (function pointers): For
1174 global functions, the PLABEL word points into the .plt
1175 two bytes past a (function address, gp) pair, and for
1176 local functions the PLABEL points directly at the
1177 function. The magic +2 for the first type allows us to
1178 differentiate between the two. As you can imagine, this
1179 is a real pain when it comes to generating code to call
1180 functions indirectly or to compare function pointers.
1181 We avoid the mess by always pointing a PLABEL into the
1182 .plt, even for local functions. */
