d6e5f95000 * section.c (SEC_DEBUGGING): New section flag.
* elfcode.h (bfd_section_from_shdr): If section is SHT_PROGBITS,
	and the name starts with .debug, .line or .stab, set
	SEC_DEBUGGING.
	* elf32-target.h (TARGET_BIG_SYM, TARGET_LITTLE_SYM): Added
	SEC_DEBUGGING to section_flags.
	* elf64-target.h (TARGET_BIG_SYM, TARGET_LITTLE_SYM): Added
	SEC_DEBUGGING and SEC_CODE to section_flags.

8b52d48669 * config/mips/tm-mips.h (STORE_STRUCT_RETURN): Define as noop as
the pushing of the struct return address is already handled in
	mips_push_arguments.
	* mips-tdep.c (reinit_frame_cache_sfunc):  Fix typo in prototype
	declaration.
	* mipsread.c (parse_symbol, parse_type, upgrade_type):  Add more
	sanity checks for corrupt symbol entries to avoid core dumps
	reported by benson@odi.com. Obviously Ultrix 4.3A cc now has
	the same problems as the OSF/1 alpha cc.
	* mipsread.c (parse_lines):  Iterate over the range of the compressed
	line number entries, the old iteration sometimes failed to stop
	and wrote past the end of the LINETABLE. Add sanity check to avoid
	the same problem in case the line number info is corrupt.
	* mipsread.c (parse_procedure):  Adjust pdr for alpha __sigtramp.
	* mipsread.c (parse_external, parse_partial_symbols):  Ignore stNil
	symbols that are produced for statics in .o files and stLocal symbols
	that are produced for every section in OSF/1 dynamically linked
	 executables.
	* mipsread.c (psymtab_to_symtab_1):  Put out `undefined symbols'
	warning only under `verbose on' as there are many undefined symbols
	in a dynamically linked executable.

c0367ba580 * objcopy.c (copy_object): Copy all applicable file flags.
(copy_file): Don't copy EXEC_P specially here.

This permits strip to generate an executable file on UnixWare;
it still does not actually strip the debugging information.

	that we pick it up from the default REMOTE_O.
