     43    knowing all the intricate details of the linker, note the
     44    following:
     45 
     46    Functions named elf32_hppa_* are called by external routines, other
     47    functions are only called locally.  elf32_hppa_* functions appear
     48    in this file more or less in the order in which they are called
     49    from external routines.  eg. elf32_hppa_check_relocs is called
     50    early in the link process, elf32_hppa_finish_dynamic_sections is
     51    one of the last functions.  */

     53 /* We use two hash tables to hold information for linking PA ELF objects.
     54 
     55    The first is the elf32_hppa_link_hash_table which is derived
     56    from the standard ELF linker hash table.  We use this as a place to
     57    attach other hash tables and static information.
     58 
     59    The second is the stub hash table which is derived from the
     60    base BFD hash table.  The stub hash table holds the information
     61    necessary to build the linker stubs during a link.
     62 
     63    There are a number of different stubs generated by the linker.
     64 
     65    Long branch stub:
     66    :		ldil LR'X,%r1
     67    :		be,n RR'X(%sr4,%r1)
     68 
     69    PIC long branch stub:
     70    :		b,l .+8,%r1
     71    :		addil LR'X - ($PIC_pcrel$0 - 4),%r1
     72    :		be,n RR'X - ($PIC_pcrel$0 - 8)(%sr4,%r1)
     73 
     74    Import stub to call shared library routine from normal object file
     75    (single sub-space version)
     76    :		addil LR'lt_ptr+ltoff,%dp	; get procedure entry point
     77    :		ldw RR'lt_ptr+ltoff(%r1),%r21
     78    :		bv %r0(%r21)
     79    :		ldw RR'lt_ptr+ltoff+4(%r1),%r19	; get new dlt value.
     80 
     81    Import stub to call shared library routine from shared library
     82    (single sub-space version)
     83    :		addil LR'ltoff,%r19		; get procedure entry point
     84    :		ldw RR'ltoff(%r1),%r21
     85    :		bv %r0(%r21)
     86    :		ldw RR'ltoff+4(%r1),%r19	; get new dlt value.
     87 
     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 procedure entry point
     91    :		ldw RR'lt_ptr+ltoff(%r1),%r21
     92    :		ldw RR'lt_ptr+ltoff+4(%r1),%r19	; get new dlt value.
     93    :		ldsid (%r21),%r1
     94    :		mtsp %r1,%sr0
     95    :		be 0(%sr0,%r21)			; branch to target
     96    :		stw %rp,-24(%sp)		; save rp
     97 
     98    Import stub to call shared library routine from shared library
     99    (multiple sub-space support)
    100    :		addil LR'ltoff,%r19		; get procedure entry point
    101    :		ldw RR'ltoff(%r1),%r21
    102    :		ldw RR'ltoff+4(%r1),%r19	; get new dlt value.
    103    :		ldsid (%r21),%r1

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