/* 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
   (single sub-space version)
   :		addil LR'ltoff,%r19		; get procedure entry point
   :		ldw RR'ltoff(%r1),%r21
   :		bv %r0(%r21)
   :		ldw RR'ltoff+4(%r1),%r19	; get new dlt value.

   Import stub to call shared library routine from normal object file
   (multiple sub-space support)
   :		addil LR'lt_ptr+ltoff,%dp	; get procedure entry point
   :		ldw RR'lt_ptr+ltoff(%r1),%r21
   :		ldw RR'lt_ptr+ltoff+4(%r1),%r19	; get new dlt value.
   :		ldsid (%r21),%r1
   :		mtsp %r1,%sr0
   :		be 0(%sr0,%r21)			; branch to target
   :		stw %rp,-24(%sp)		; save rp

   Import stub to call shared library routine from shared library
   (multiple sub-space support)
   :		addil LR'ltoff,%r19		; get procedure entry point
   :		ldw RR'ltoff(%r1),%r21
   :		ldw RR'ltoff+4(%r1),%r19	; get new dlt value.

   :		mtsp %r1,%sr0
   :		be 0(%sr0,%r21)			; branch to target
   :		stw %rp,-24(%sp)		; save rp

   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.
   :		bl,n X,%rp			; trap the return
