symbol strings.
(som_finish_writing): Write them here. Place them after the
subspace data, but before the relocs.
Works around a truely stupid bug in the hpux8/hpux9 linker. Fixes all
known link-time problems with -mlinker-opt.
nonzero when we're generating relocations for an expression
using the difference of two symbols. All callers changed.
Handle difference of symbols for both R_HPPA and R_COMPLEX
cases.
(som_write_fixups): Handle R_COMP1, R_COMP2 and R_CODE_EXPR
fixups.

structures.

different variants of the PA architecture.

PA1.1 machine identifier in the output file.
braindamaged HP OSF1 linker.
(setup_sections): Don't forget to free subspace_sections if we get
an error.
(som_slurp_string_table): Allocate strings on this bfd's obstack
rather than directly out of the heap.
(som_slurp_symbol_table): Likewise for the saved copy of the
canonical symbols.
(som_slurp_reloc_table): Likewise for the saved copy of the
canonical relocations. Free the native relocations when we're
done with them.
* som.c (som_write_symbol_strings): Use "stringtab_offset"
rather than destroying the "name" field in the BFD symbol.
(som_build_and_write_symbol_table): Likewise.
'T' and 'U' to grab all the unwind information.
(som_set_reloc_info): Make 'U' unwind bits persist across
multiple SOM relocations. Set the addend field of an R_ENTRY
relocation to the value in 'T'; set the addend field on an
R_EXIT relocation to the value in 'U'.
* som.c (som_write_fixups): For R_ENTRY fixups, get 32bits of
unwind information from the addend field of the R_ENTRY, get the
other 32bits from the addend field of the R_EXIT.
(bfd_som_attach_unwind_info): Delete function and all references.
switched in executables created by the OSF1 linker.
(som_write_fixups): Handle R_EXIT just like the R_{F,L,R}SEL
fixups. Support R_ALT_ENTRY (handle just like R_EXIT).
R_NO_RELOCATION fixups.
(bfd_section_from_som_symbol): Return the absolute section if the
symbol isn't contained in any section in the output file.
(som_slurp_symbol_table): ST_PRI_PROG and ST_SEC_PROG symbols are
not function symbols (they are magic code labels which *can* be the
targets of cross space branches). $START$ is not a section symbol.
allocate and attach an exec header to the BFD private data.
(som_begin_writing): Don't fill fields of the exec header based
on BFD private data here (like the exec flags). Do not write
the exec header here.

file header.
(obj_som_exec_hdr): New accessor macro.
or HIUX_AUX_ID.
(som_begin_writing): Use EXEC_AUX_ID instead of HPUX_AUX_ID.
(som_write_armap): Use CPU_PA_RISC1_0 as the magic number. Note
som.c is careful to always define CPU_PA_RISC1_0.

(BFD_JUMP_TABLE_WRITE, BFD_JUMP_TABLE_LINK): Defined.
* All backends: Changed to use the new BFD_JUMP_TABLE_* macros
rather than the single JUMP_TABLE macro. Removed many of the
weird macro definitions needed to support the monolithic
JUMP_TABLE.
* bfd-in.h (JUMP_TABLE): Removed.
* libbfd-in.h: Define a bunch of macros, and declare a few
functions, for use with the new BFD_JUMP_TABLE_* macros.

bfd_generic_get_section_contents. Changed all callers.
(_bfd_generic_set_section_contents): Similar rename.
* ieee.c: #if 0 out ieee_bfd_debug_info_start,
ieee_bfd_debug_info_end, ieee_bfd_debug_info_accumulate. They
were never called.

* som.c (som_object_setup): Set DYNAMIC flag for SHL_MAGIC and
DL_MAGIC objects.
(som_prep_headers): Preserve the system_id for DYNAMIC objects.
Use SHL_MAGIC as the magic number of the DYNAMIC flag is set.
Write exec headers for DYNAMIC objects.
(som_begin_writing): DYNAMIC objects have the same alignment
restrictions as D_PAGED objects.
(bfd_section_from_som_symbol): Treat DYNAMIC objects like EXEC_P
objects.
(object_flags): Add DYNAMIC.
section->relocation is NULL; malloc might have returned NULL when
given a zero size if there were no relocations.

relocation tables.
(som_bfd_free_cached_info): Free the cached native strings,
symbols, and relocations. Also free the canonical cached relocations.
in executables left by the HP linker. Does not rely on subspace
alignments as subspaces are *NOT* guaranteed to be properly
aligned in an executable (can you believe that!).
read. (bfd_error_system_call or bfd_error_file_truncated).
* som.c: Do not blindly set bfd_error_system_call after a
failing bfd_read, bfd_write, or bfd_seek. In a few places
(like som_object_p) override the error status set by bfd_read.

calls that we just assumed were not failing.
som_section_from_subspace_index. Pass in a native SOM symbol.
For executables, iterate through the sections to find out
which contains the symbol's address rather than using the
symbol_info field. (symbol_info has a different meaning for
dynamicly linked executables.)
subspaces too when writing executables. Never request a negative
bss size. Fixes some problems with demand paged executables,
still having problems with pure executables and shared executables.
