41 knowing all the intricate details of the linker, note the
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

48 early in the link process, elf32_hppa_finish_dynamic_sections is
49 one of the last functions. */
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.
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
59 necessary to build the linker stubs during a link.
61 There are a number of different stubs generated by the linker.
69 : addil LR'X - ($PIC_pcrel$0 - 4),%r1
70 : be,n RR'X - ($PIC_pcrel$0 - 8)(%sr4,%r1)
72 Import stub to call shared library routine from normal object file
73 (single sub-space version)
74 : addil LR'lt_ptr+ltoff,%dp ; get procedure entry point
75 : ldw RR'lt_ptr+ltoff(%r1),%r21
77 : ldw RR'lt_ptr+ltoff+4(%r1),%r19 ; get new dlt value.
79 Import stub to call shared library routine from shared library
80 (single sub-space version)
81 : addil LR'ltoff,%r19 ; get procedure entry point
82 : ldw RR'ltoff(%r1),%r21
84 : ldw RR'ltoff+4(%r1),%r19 ; get new dlt value.
86 Import stub to call shared library routine from normal object file
87 (multiple sub-space support)
88 : addil LR'lt_ptr+ltoff,%dp ; get procedure entry point
89 : ldw RR'lt_ptr+ltoff(%r1),%r21
90 : ldw RR'lt_ptr+ltoff+4(%r1),%r19 ; get new dlt value.
93 : be 0(%sr0,%r21) ; branch to target
94 : stw %rp,-24(%sp) ; save rp
96 Import stub to call shared library routine from shared library
97 (multiple sub-space support)
98 : addil LR'ltoff,%r19 ; get procedure entry point
99 : ldw RR'ltoff(%r1),%r21
100 : ldw RR'ltoff+4(%r1),%r19 ; get new dlt value.
103 : be 0(%sr0,%r21) ; branch to target
104 : stw %rp,-24(%sp) ; save rp
106 Export stub to return from shared lib routine (multiple sub-space support)
107 One of these is created for each exported procedure in a shared
108 library (and stored in the shared lib). Shared lib routines are
109 called via the first instruction in the export stub so that we can
110 do an inter-space return. Not required for single sub-space.
111 : bl,n X,%rp ; trap the return
113 : ldw -24(%sp),%rp ; restore the original rp
116 : be,n 0(%sr0,%rp) ; inter-space return. */
