/* In order to gain some understanding of code in this file without
   knowing all the intricate details of the linker, note the
   following:

   Functions named elf32_hppa_* are called by external routines, other
   functions are only called locally.  elf32_hppa_* functions appear
   in this file more or less in the order in which they are called
   from external routines.  eg. elf32_hppa_check_relocs is called
   early in the link process, elf32_hppa_finish_dynamic_sections is
   one of the last functions.  */

/* We use two hash tables to hold information for linking PA ELF objects.

   The first is the elf32_hppa_link_hash_table which is derived
   from the standard ELF linker hash table.  We use this as a place to
   attach other hash tables and static information.

   The second is the stub hash table which is derived from the
   base BFD hash table.  The stub hash table holds the information
   necessary to build the linker stubs during a link.

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

   Long branch stub:
   :            ldil LR'X,%r1
   :            be,n RR'X(%sr4,%r1)

   PIC long branch stub:
   :            b,l .+8,%r1
   :            addil LR'X - ($PIC_pcrel$0 - 4),%r1
   :            be,n RR'X - ($PIC_pcrel$0 - 8)(%sr4,%r1)

   Import stub to call shared library routine from normal object file
   (single sub-space version)
   :            addil LR'lt_ptr+ltoff,%dp       ; get procedure entry point
   :            ldw RR'lt_ptr+ltoff(%r1),%r21
   :            bv %r0(%r21)
   :            ldw RR'lt_ptr+ltoff+4(%r1),%r19 ; get new dlt value.

   Import stub to call shared library routine from shared library

   :            ldw RR'ltoff(%r1),%r21
   :            bv %r0(%r21)
   :            ldw RR'ltoff+4(%r1),%r19        ; get new dlt value.

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

             the reloc into the shared library.  However, if we are
             linking with -Bsymbolic, we need only copy absolute
             relocs or relocs against symbols that are not defined in
             an object we are including in the link.  PC- or DP- or
             DLT-relative relocs against any local sym or global sym
             with DEF_REGULAR set, can be discarded.  At this point we
             have not seen all the input files, so it is possible that
             DEF_REGULAR is not set now but will be set later (it is
             never cleared).  We account for that possibility below by
             storing information in the dyn_relocs field of the
             hash table entry.

             A similar situation to the -Bsymbolic case occurs when
             creating shared libraries and symbol visibility changes
             render the symbol local.

             As it turns out, all the relocs we will be creating here
             are absolute, so we cannot remove them on -Bsymbolic
             links or visibility changes anyway.  A STUB_REL reloc
             is absolute too, as in that case it is the reloc in the
             stub we will be creating, rather than copying the PCREL
             reloc in the branch.

             If on the other hand, we are creating an executable, we
             may need to keep relocations for symbols satisfied by a
             dynamic library if we manage to avoid copy relocs for the
             symbol.  */
