HAS_RELOC based on the object's magic number.
(make_unique_section): Delete function. BFD and its users are
prepared to handle multiple sections with the same name.
(setup_sections): Allocate space on the BFD's obstack to hold
section names. Use bfd_make_setion_anyway rather than the
obsolete make_unique_section.
(som_prep_headers): Choose the correct SOM magic number based
on the BFD's flags.
(som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
cruft (like the #pragma alloca for AIX).
In addition to that problem, the C alloca calls xmalloc, which
means checking for being out of memory can't work right. The
following changes remove all uses of alloca from BFD.
* hosts/solaris2.h: Remove alloca cruft.
* som.c: Replace alloca with a fixed size auto array.
* aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c:
Replace alloca with malloc and appropriate error checking and
freeing.
* linker.c: Replace alloca with obstack_alloc.
* libbfd.h: Rebuilt.
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.
surely remain as this hasn't been tested all that much.
* som.c (SOM_LST_HASH_SIZE, SOM_LST_MODULE_LIMIT): Define.
(struct som_misc_symbol_info): New structure to hold info necessary
to build both normal and library symbol tables.
(som_derive_misc_symbol_info): New function to derive info necessary
to build both normal and library symbol tables.
(som_build_and_write_symbol_table): Use new function to derive misc
symbol information.
(som_slurp_symbol_table): Update backend private data for symbols
appropriately.
(som_bfd_prep_for_ar_write): New function.
(som_bfd_ar_symbol_hash): New function.
(som_bfd_ar_write_symbol_stuff): New function.
(som_write_armap): Flesh out.
(som_vec): Fix ar padding character.
* som.c: Consistently use memset rather than bzero.
auxiliary headers.
(bfd_som_attach_aux_hdr): New function.
* som.h (struct somdata): Add fields for attaching version and
copyright headers. Add accessor macros.
definitions for old versions of HPUX which fail to define them.
(som_hppa_howto_talbe): Add R_DLT_REL, R_AUX_UNWIND, and R_SEC_STMT
now that they're safe. Delete bogus R_STATEMENT relocations.
extra R_DATA_OVERRIDE.
(hppa_som_gen_reloc_type): Generate a relocation for the rounding
mode selector if needed.
(som_write_fixups): Handle requests for a change in the default
rounding mode. Rounding modes do not consume input bytes, but
are just markers much like R_ENTRY and R_EXIT.
the last four multibyte relocations emitted.
(enum pa_symbol_type): Type to fully describe the symbol types
associated with .import/.export assembler directives.
These changes separate PA-SOM support from PA-ELF support.
A sun4-x-hppaosf assembler can now be built.
* elf32-hppa.c (elf_hppa_howto_table): Now static.
(symext_rootP, symext_lastP, global_value, GOT_value, global_symbol,
global_sym_defined, symextn_contents, symextn_contents_real_size,
elf_hppa_stub_rootP, elf32_hppa_symextn_map, elf32_hppa_symextn_map_size): Rely
on default initialization.
(hppa_elf_gen_reloc_type): Macro "UNDEFINED" doesn't need a trailing semicolon.
(hppa_look_for_stubs_in_section): Introduce temporaries to make code more
readable in 80 columns.
* libhppa.h (all functions): Now inline under GNU C.
* elf32-hppa.c (AR_WARN): Give argument which caused the invalid argument
relocation.
(AR_UNIMP): Delete unused macro.
(hppa_elf_set_section_contents): Always return a value.
(elf32_hppa_backend_table_processing): Likewise.
(elf32_hppa_backend_section_processing: Likewise.
* som.c: New file containing SOM specific code extracted from hppa.c
* 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.
* elf32-hppa.h (hppa_reloc_field_selector_type): Delete now lives in libhppa.h.
(hppa_reloc_field_selector_type_alt): Likewise.
* elf32-hppa.c (hppa_elf_relocate_unwind_table): Delete unused variables.
(elf_hppa_reloc_type_lookup): Likewise.
(elf_hppa_tc_make_sections): Likewise.
(hppa_elf_arg_reloc_needed_p): Likewise.
(hppa_elf_build_long_branch_stub): Likewise.
(elf_reloc_map): Delete, no longer used.
(elf_hppa_reloc_map): Likewise.
(elf32_hppa_symextn_map_max_size): Likewise.
(elf32_hppa_get_sym_extn): Abort if type is bogus.
* elf32-hppa.c (elf32_hppa_backend_fake_sections): Add processing
of the .hppa_unwind section.
