38 /* In order to gain some understanding of code in this file without
39 knowing all the intricate details of the linker, note the
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. */
49 /* We use two hash tables to hold information for linking PA ELF objects.
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.
59 There are a number of different stubs generated by the linker.
67 : addil LR'X - ($PIC_pcrel$0 - 4),%r1
68 : be,n RR'X - ($PIC_pcrel$0 - 8)(%sr4,%r1)
70 Import stub to call shared library routine from normal object file
71 (single sub-space version)
72 : addil LR'lt_ptr+ltoff,%dp ; get procedure entry point
73 : ldw RR'lt_ptr+ltoff(%r1),%r21
75 : ldw RR'lt_ptr+ltoff+4(%r1),%r19 ; get new dlt value.
77 Import stub to call shared library routine from shared library
78 (single sub-space version)
79 : addil LR'ltoff,%r19 ; get procedure entry point
80 : ldw RR'ltoff(%r1),%r21
82 : ldw RR'ltoff+4(%r1),%r19 ; get new dlt value.

85 (multiple sub-space support)
86 : addil LR'lt_ptr+ltoff,%dp ; get procedure entry point
87 : ldw RR'lt_ptr+ltoff(%r1),%r21
88 : ldw RR'lt_ptr+ltoff+4(%r1),%r19 ; get new dlt value.
91 : be 0(%sr0,%r21) ; branch to target

104 Export stub to return from shared lib routine (multiple sub-space support)
105 One of these is created for each exported procedure in a shared
106 library (and stored in the shared lib). Shared lib routines are
107 called via the first instruction in the export stub so that we can
108 do an inter-space return. Not required for single sub-space.
