* bfd-in.h: Added swapping routine declarations, and renamed them
from _do_* to bfd_*.

references.
(nlm_swap_auxiliary_headers_{in,out}): The copyright length is
only one byte.
(nlm_get_symtab_upper_bound): Include debugging symbols in symbol
count.
(nlm_slurp_symbol_table): Make symlength unsigned. Read debugging
symbols as BFD local symbols.
(nlm_write_object_contents): Don't bother writing out exported
symbols more than once; they now appear in the symbol table more
than once (with and without a prefix) if necessary. Set offset
values to be non-zero as NLMLINK does.
These changes separate PA-SOM support from PA-ELF support.
A sun4-x-hppaosf assembler can now be built.
Include <stdlib.h> and <unistd.h>. Do not define malloc or free.

readable in 80 columns.

* som.h: New file containing SOM specific code extracted from libhppa.h
* hppa.c: Deleted.
* libhppa.h: Delete SOM specific code. Add generic PA code which can be shared
by both SOM and ELF backends.
* Makefile.in: Replace hppa.c with som.c. elf32-hppa.o depends on libhppa.h
now.
* configure.in (hppa_vec): Needs som.o module instead of hppa.o.
* elf32-hppa.c: Include libhppa.h. Do not define BYTES_IN_WORD.

of the .hppa_unwind section.
(bfd_shdr_from_section): Ditto.
(write_relocs): Don't change section contents for addend.
(elf_locate_sh): Return type is now always elf_internal_shdr, since the other
types were really aliases for this type anyways. Don't compile this function,
since it is static and doesn't appear to be used in this file.
(sym_is_global): Return non-zero for weak symbols. Abort if sec ptr is null.
(swap_out_syms): Reorder tests so function symbols can be weak.
(elf_slurp_symbol_table): Don't use BSF_EXPORT.

array of pointers to section symbols.

that we don't overwrite memory. Store the max index into the
elf_obj_tdata field.
Sat Jun 19 10:12:27 1993 Michael Meissner (meissner@osf.org)
* elfcode.h (elf_obj_tdata): Add pointer to an array of pointers
to the section symbols we created. Remove unused field internal_syms.
(elf_map_symbols): Fill in array of pointers to section symbols. Only create
section symbols for sections that have SEC_ALLOC set, and have non-zero size.
(elf_symbol_from_bfd_symbol): If udata is NULL, and this is a section symbol,
look up the section in the list of section symbols, and set the udata pointer
appropriately. Otherwise, if udata is still NULL, fail an assertion, and use
0, instead of dropping core.

support S-records, for convenience.

(nlm_set_section_contents): Remove argument names from
mangle_relocs_func prototype.
(nlm_write_object_contents): Remove shadowing local variable.
Don't write out debugging symbols if debugInfoOffset is -1. Add
the codeImageOffset to the start, exit, and check procedure
offsets.
* nlm32-i386.c (nlm_i386_write_reloc, nlm_i386_mangle_relocs):
Don't check partial_inplace field; its value is irrelevant.
* configure.host (i[34]86-*-sco*): Use i386sco rather than i386v.
* config/i386-sco.mt (TDEFINES): Removed.
* config/i386sco.mh: New file to use sco-core.

Fix comment about checking for matching byte order. Preserve
pointer to old tdata (if any), and restore it if we don't match
file with target vector. If we are going to use goto's, use them
consistently and maintainably.
* nlmcode.h (nlm_object_p): Expand comments about leaked memory
to note that the problem is even more serious than just leaked
memory. Replace goto with more traditional return.

Tue Jun 15 14:38:32 1993 Michael Meissner (meissner@osf.org)
* libelf.h (elf_hash): Change declaration to bfd_elf_hash, since
that is what is in elf.c.
* elfcode.h (elf_write_object_contents): Don't drop core if
elf_symbol_from returns a NULL pointer when processing a non-elf
symbol, use a 0 size instead.
Tue Jun 15 14:38:32 1993 Michael Meissner (meissner@osf.org)
* elfcode.h (elf_hash): Delete macro mapping elf_hash to
bfd_elf32_hash, since the hash table is independent of the 32/64
bit system.
