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.
* 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.
* 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.
* elf32-hppa.c: Change .hppa_linker_stubs to .PARISC.stubs,
likewise for other PA specific sections.
(hppa_elf_relocate_unwind_table): Delete unused
function.
(elf_hppa_howto_table): Completely new table based on 94-02-02
draft PA ELF spec. Change relocation tags appropriately
throughout elf32-hppa.c
(hppa_elf_gen_reloc_type): Rewrite and simplify based on 94-02-02
spec.
(hppa_elf_reloc): Likewise.
(hppa_look_for_stubs_in_section): Likewise
(ELF_MACHINE_CODE): Change to EM_PARISC.
* elf32-hppa.h: Include "elf/hppa.h". Change relocation tags
appropriately throughout elf32-hppa.h.
(elf32_hppa_reloc_type): New table based on 94-02-02 draft PA ELF
spec.
(R_HPPA_ABS_CALL, R_HPPA_COMPLEX*, R_HPPA_UNWIND): Delete definitions.
* elfcode.h (prep_headers): Use EM_PARISC instead of EM_HPPA.
* reloc.c (bfd_reloc_code_real): Delete unused HPPA relocations.
* som.h (R_HPPA_ABS_CALL, R_HPPA_COMPLEX): Delete definitions.
* libhppa.h (hppa_field_adjust): Avoid adding constant_value into
the final value twice for LR and RR field selectors.
info that must be preserved when running objcopy/strip.
(struct somdata): Add new "exec_data" field and accessor
macro. Add some comments on how the various fields are used.
(som_section_data_struct): Make is_space and is_subspace bitfields.
Delete unused subspace_index. All references now use the
target_index field within the section structure itself.
* som.c (make_unique_section): Delete unused declaration.
(som_bfd_copy_private_bfd_data): New function.
(som_object_setup): Allocate space for and save exec information
that needs to be copied during objcopy/strip.
(som_mkobject): Do not allocate space for a file header here.
It is not used when only reading SOM objects.
(som_prep_headers): Allocate space for and attach a file header
to the output bfd. For executables, use the saved system_id
value rather than trying to guess the right value. Do not abort
wwhen setting file_hdr->entry* for executables.
(som_begin_writing): For executables, set the exec_entry and
exec_flags fields.
(som_copy_private_backend_section_data): Always return a value.
field parameter.
(bfd_som_set_section_attributes): Use unsigned int rather than
unsigned char to avoid GNU-C extensions.
(bfd_som_attach_aux_hdr): Return a boolean to indicate success
or failure rather than aborting on failure.
* som.h (bfd_som_set_section_attributes): Fix prototype to match
som.c changes.
(bfd_som_attach_aux_hdr): Add prototype.
(hppa_som-gen_reloc_type): Likewise.
* elf32-hppa.c: Add a couple casts to make HP compiler happy.
(hppa_look_for_stubs_in_section): Do not return false on failure
until rest of code is ready to handle it. Abort for now.
information needed to build/write symbol tables and fixup streams.
(struct som_section_data_struct): Add new fields to hold additional
information needed to build/write space and subspace headers.
(som_symbol_data): New accessor macro for SOM symbol information.
(R_HPPA_*): Basic relocation types to be used by the assembler.
