5e7be5310d * lib/gdb.exp(default_gdb_exit): Don't give an error if the remote
host doesn't have a currently-open connection.

	* config/sparclet.exp: Cleanups and fixes to make it generic for
 	any gdb stub target. Handle cases where gdb doesn't respond when
 	interrupted in a sane fashion.

	* config/m32r.exp: Load sparclet.exp instead of trying to do the
 	same thing in a totally different way.

	* config/monitor.exp: Pass in timeouts to gdb_expect instead of
 	setting "timeout".
	(gdb_start): We set the global gdb_prompt variable in
 	default_gdb_init now.

d05b86b7fb * interp.c (sim_resume): Clear State.exited.
(sim_stop_reason): If State.exited is nonzero, then indicate that
        the simulator exited instead of stopped.
        * mn10300_sim.h (struct _state): Add exited field.
        * simops.c (syscall): Set State.exited for SYS_exit.

Fixes problem found bin Felix.

541a4b5425 * elflink.h (elf_merge_symbol): In the case of a new defined
symbol overriding an old defined symbol, return the hash table
	entry which we modify, even if it is the target of an
	indirection.
	(elf_link_add_object_symbols): If the real name of the symbol gets
	overridden, convert the versioned symbol into an indirect symbol
	to the real symbol.

c80c4a58df * configure.in: Don't set ENABLE_MULTILIB, so we'll be passing
--enable-multilib down to subdirs; setting TARGET_SUBDIR was enough.

	(new_symbol): Ditto.

b682323727 * procfs.c (proc_set_exec_trap, procfs_init_inferior, procfs_wait,
unconditionally_kill_inferior):  Undo Oct 26 1996 and Apr 26 1997
	changes to trace PRFS_STOPTERM and handle PR_DEAD.
	These changes tried to work around a problem with an early DU 4.0
	release, but they trigger subtle timing dependent kernel bugs
	in older OSF/1 releases.

* scripttempl/elfppc.sc: Correct .rela.sdata entries.

	* scripttempl/elfppc.sc: Put the PLT between the small and large
	BSS segments.
	* emulparams/elf32ppc.sh (TEXT_START_ADDR): The ABI says `A
	program base of 0x02000000 is recommended...' because otherwise
	shared libraries are less efficient.  We use 0x01800000 because
	otherwise it's impossible to branch to location 0, for instance if
	you have an undefined weak symbol.

24a3e62262 Mon Jun 16 19:12:51 1997 Geoff Keating <geoffk@ozemail.com.au>
* config/tc-ppc.h (tc_fix_adjustable): Don't let the assembler
	calculate relocations to any external symbol, because we might be
	linking a shared object and the symbol might be overriden or moved
	(for instance, moved into a static executable's .bss section).
	(GLOBAL_OFFSET_TABLE_NAME): Delete. This is an i386 wierdness.

	* config/tc-ppc.h (tc_fix_adjustable): GOT-based relocations can't
	be calculated by the assembler.

	* config/tc-ppc.c (md_apply_fix3): Handle @plt or @local branch
	whose destination lies in the same file, by ignoring the @plt or
	@local and aiming the branch at its destination.

* elf32-ppc.c (ppc_elf_relocate_section): Don't emit R_PPC_REL*
 	relocs in shared libraries which refer to local symbols.  Cope
 	with addend when processing a GOT relocation.

	* elf32-ppc.c (ppc_elf_size_dynamic_sections): Only create symbols
	for sections that the linker didn't create.
	(ppc_elf_finish_dynamic_sections): Only try to write out a section
 	symbol if it was created in ppc_elf_size_dynamic_sections.
	(ppc_elf_relocate_section): Complain if we have to generate a reloc
	relative to a section for which we didn't output a symbol.

	* elf32-ppc.c (ppc_elf_size_dynamic_sections): Clean up.  PLT
 	relocs are 'rela' relocs, like everything else.  .rela.plt is not
 	a read-only section, so we don't have to special-case it.

	* elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Entries in the
	.rela.bss section are (of course) 'rela' relocs not 'rel' relocs.

	* elf32-ppc.c (ppc_elf_check_relocs): Initialise srelgot.
	(ppc_elf_relocate_section): @got offsets are 4 from start of the
	actual .got section.
	* elflink.c (_bfd_elf_create_got_section): The three reserved
	words start from the symbol '_GLOBAL_OFFSET_TABLE_'.

	* elf32-ppc.c (ppc_elf_size_dynamic_sections): '.rela' is 5
	characters, not 4.

	* elf32-ppc.c (ppc_elf_check_relocs): Use
	_bfd_elf_create_got_section to create the GOT rather than
	ppc_elf_create_linker_section. Create the '.rela.got' section
	ourselves.
	(ppc_elf_finish_dynamic_symbol): Set up GOT relocations when a
	symbol has a GOT entry.
	(ppc_elf_relocate_section): Record when a symbol is used through
	the GOT, and allocate space in the GOT for each such symbol.
	(ppc_elf_adjust_dynamic_symbol): Delete unused .got.plt stuff.
	(ppc_elf_create_linker_section): Delete unused LINKER_SECTION_GOT
	stuff.

	* elf32-ppc.c (ppc_elf_howto_raw): GOT16_HA relocs should be
	treated in a similar way to ADDR16_HA relocs.
	(ppc_elf_relocate_section): PLTREL24 relocs do not get copied into
	shared objects; the linker must deal with them.
	(ppc_elf_create_linker_section): Stop setting
	_GLOBAL_OFFSET_TABLE_ to the wrong value; delete unused
	LINKER_SECTION_PLT stuff.
	(ppc_elf_check_relocs): Delete unused LINKER_SECTION_PLT stuff.
	(ppc_elf_finish_dynamic_sections): Use BFD calls to get GOT
	section, not ELF-specific calls.
	(elf_backend_plt_not_loaded): Set to 1.
	(elf_backend_got_symbol_offset): Set to 4.
	* elf-bfd.h (elf_backend_data): Add 'plt_not_loaded' member
	for when ld.so fills in the PLT; and 'got_symbol_offset' member.
	* elflink.c (_bfd_elf_create_dynamic_sections): Apply
	plt_not_loaded member.
	(_bfd_elf_create_got_section): Apply got_symbol_offset.
	* elfxx-target.h (elf_backend_plt_not_loaded): Set default to
	'loaded'.
	(elf_backend_G_O_T_offset): Set default to 0.
	(elfNN_bed): Set added fields.

	* elf32-ppc.c (ppc_elf_size_dynamic_sections): Was setting
	DT_RELENT in shared objects; should be DT_RELAENT.

	* elf32-ppc.c (ppc_elf_relocate_section): Propagate
	R_PPC_ADDR16_HA relocs to shared objects. Cope with case where
	such a reloc (in a non-shared object) refers to a symbol that's
	not defined.

3a0358617e * config/tc-ppc.c (ppc_insert_operand): In 32 bit mode, with a
signed operand, sign extend a 32 bit value to the host size.
Permits dubious usage like
	addi  %r6,%r6,0xfffffeff
to assemble on a 64 bit host as it does on a 32 bit host.
