elfcode.h (FILE_ALIGN_: Renamed from EALIGN, to avoid conflict with Ultrix

header files.

Also, lots of changes for PA elf and som support from Utah; see ChangeLog
for details.

+
+	* elfcode.h (FILE_ALIGN): Renamed from EALIGN, to avoid conflict
+	with Ultrix header files.
+
+	* som.h (struct som_section_data_struct): Renamed from
+	som_section_data to avoid conflict with macro by that name.
+
+	Changes from Jeff Law and Peter Hoogenboom at Utah:
+
+	* elf32-hppa.c (hppa_elf_reloc):  Target register for a 'jump
+	in delay slot' optimization in combination with a long call
+	stub should always be r31.
+
+	* elf32-hppa.c: (hppa_elf_relocate_insn): To be consistent
+	across all relocation types, retrieve instruction addends from
+	the relocation entry rather than from the instruction itself.
+
+	* elf32-hppa.c: (hppa_elf_relocate_insn): Fix a relocation
+	error that only occurred when the addend of an 'addil' or
+	'ldil' was larger than 21 bits and very close to a 2K byte
+	boundary.
+
+	* elf32-hppa.c: (hppa_elf_reloc):  Handle the optimization in
+	which a jump is placed in the delay slot of a function call.
+	The jump was being accomplished via an adjustment to the
+	return pointer.  This optimization would break the long call
+	stub code, if there was any.
+
+	* elf32-hppa.c: (hppa_elf_build_long_branch_stub): Corrections
+	to long branch stubs to avoid use of general register 2.
+
+	* hppa_stubs.h: New stub instructions.
+
+	* elfcode.h: Declare bfd_elf_find_section.
+
+	* som.h (som_section_data): Add new "subspace_index" field.
+
+	* som.c (setup_sections): Save the original SOM subspace index
+	in the BFD section associated with that subspace.  
+	(som_get_symtab_upper_bound): Implement.
+	(som_get_symtab): Implement.
+	(som_print_symbol): Implement.
+	(som_slurp_string_table): New function to read a string table
+	from a SOM object file.
+	(som_section_from_subspace_index): New function to return the
+	section which corresponds to a SOM subspace index.
+	(som_slurp_symbol_table): New function to read the symbol
+	table from a SOM object file.
+	(som_make_empty_symbol): Check for errors from bfd_zalloc.
+	(som_new_section_hook): Initialize subspace_index field to
+	-1 instead of 0.
+
+	* som.c (som_object_setup): Fix polarity of test to set HAS_RELOC.
+	Set EXEC_P for executables.
+	(setup_sections): Correctly identify when a section has
+	relocations.
+	(log2): New function.
+	(setup_sections): Correctly convert between SOM alignments and BFD
+	alignments.
+
+	* som.c (setup_sections): Do not set SEC_ALLOC or SEC_LOAD
+	for sections which correspond to SOM spaces, doing so confuses
+	many utilities.  Set assorted SEC_* flags for SOM subspaces
+	which correspond to BFD sections.
+
+	* elf32-hppa.c: (elf32_hppa_backend_fake_sections): The stab
+	string table should have sh_type == SHT_STRTAB.  Add
+	processing to make it so.
+
+	* elfcode.h: (bfd_section_from_shdr): String tables (other
+	than .strtab) were not getting the file offsets recorded, so
+	they could not be read from disk.
+
+	* elfcode.h: (elf_make_sections):  Leave the sh_addr field of
+	the section header and the vma field of a section at 0 if the
+	section is not part of the program execution image. (e.g.,
+	.stab)
+
+	* som.[hc]: Change target vector prefix from "hppa" to "som".
+	Consistently use obj_som prefix to access fields in backend data
+	structures.  Fix all callers/references.
+
+	* som.h: Do not include files only needed for core file reading here.
+	Include a.out for both HOST_HPPAHPUX and HOST_HPPABSD.  Delete
+	forward structure declarations, they are unnecessary.
+	(struct somdata): Delete aux_hdr, and hp_symbol_entry_size fields.
+	Change "symbols" to "symtab".  Add "stringtab" and "reloc_filepos"
+	fields for future use.  Change obj_som_* macros as appropriate.
+	(som_section_data): New structure to keep SOM specific information
+	about BFD sections (for future use).
+
+	* som.c: Provide PARAMS declarations for all functions currently
+	in this file.
+	(struct container): Delete unwanted structure definition.
+	(som_object_setup): Add comments.  Use som_mkobject to allocate
+	SOM specific information in the BFD; use information from the
+	file and (possibly empty) auxiliary headers to initialize this
+	information.  Delete redundant bfd_get_symcount (abfd) "calls".
+	(setup_sections): Return type is now boolean, fix return statements.
+	"Fix" handling of BSS like subspaces in the computation of the
+	containing space's size.  If the subspace has relocations, set the
+	appropriate BFD section flags and record the index into and the
+	size of the fixup stream.  Always return a value.
+	(som_object_p): Set bfd_error appropriately if errors are detected
+	from bfd_{read,seek} functions.  Handle EXECLIBMAGIC type files.
+	Do not try to read a non-existant auxiliary header.
+	(som_mkobject): Flesh out.
+	(som_section_hook): Allocate space to hold SOM specific information
+	about sections.
