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 PLT address
75 : ldo RR'lt_ptr+ltoff(%r1),%r22 ;
76 : ldw 0(%r22),%r21 ; get procedure entry point
78 : ldw 4(%r22),%r19 ; get new dlt value.
80 Import stub to call shared library routine from shared library
81 (single sub-space version)
82 : addil LR'ltoff,%r19 ; get PLT address
83 : ldo RR'ltoff(%r1),%r22
84 : ldw 0(%r22),%r21 ; get procedure entry point
86 : ldw 4(%r22),%r19 ; get new dlt value.
88 Import stub to call shared library routine from normal object file
89 (multiple sub-space support)
90 : addil LR'lt_ptr+ltoff,%dp ; get PLT address
91 : ldo RR'lt_ptr+ltoff(%r1),%r22 ;
92 : ldw 0(%r22),%r21 ; get procedure entry point
93 : ldsid (%r21),%r1 ; get target sid
94 : ldw 4(%r22),%r19 ; get new dlt value.
96 : be 0(%sr0,%r21) ; branch to target
97 : stw %rp,-24(%sp) ; save rp
99 Import stub to call shared library routine from shared library
100 (multiple sub-space support)
101 : addil LR'ltoff,%r19 ; get PLT address
102 : ldo RR'ltoff(%r1),%r22

107 : be 0(%sr0,%r21) ; branch to target
108 : stw %rp,-24(%sp) ; save rp
110 Export stub to return from shared lib routine (multiple sub-space support)
111 One of these is created for each exported procedure in a shared
112 library (and stored in the shared lib). Shared lib routines are
113 called via the first instruction in the export stub so that we can
114 do an inter-space return. Not required for single sub-space.
115 : bl,n X,%rp ; trap the return
117 : ldw -24(%sp),%rp ; restore the original rp
120 : be,n 0(%sr0,%rp) ; inter-space return. */
