if symbols are not yet loaded.

inferior process.
(sharedlibrary_command): Made static.
Do not check for new shared libraries if there is no inferior process.
Add symbols for requested shared libraries via vmap_add_symbols.

directly, as xcoffsolib.c is now compiled in native AIX configurations
only.

arch-utils.{h,c}. The ``set architecutre'' and ``set endian''
commands (part of the move) were implemented to use add_set_enum_cmd()
so that ``set architecture <tab>'' works.
Make Sparc a Multi-Arch target. Discard PARAMS macro (require ANSI).

instead of the defunct struct frame_saved_regs.
(supply_gregset): Discard unnecessary 'zerobuf': just send NULL to
supply_register. Provide 4-byte offset to compensate for diff
between size of the prgreg_t elements on a 64-bit host and size
of the registers for a 32-bit target. Fill all inaccessible regs
with zero so they won't keep being requested again and again.

and prgreg_t. Handle as many new 64-bit regs as possible.
(supply_fpregset, fill_fpregset): Attempt to handle 64-bit world.
(sparc_push_arguments): Rename to sparc32_push_arguments.

(struct gdbarch_tdep): Define, use for private multi-arch data.
* config/sparc/tm-sparc.h: Move definitions around, enclose with
#ifdef GDB_MULTI_ARCH tests, provide some multi-arch alternate
definitions. Add enums for register names, to help debugging gdb.
This header file must work for non-multi-arch and for multi-arch.
* config/sparc/tm-sp64.h: Add GDB_MULTI_ARCH configuration. Also add
AT_ENTRY_POINT definitions for CALL_DUMMY, for non-multi-arch case.
Define GDB_MULTI_ARCH.
* config/sparc/tm-sparclet.h: Add GDB_MULTI_ARCH configuration.
Do not define GDB_MULTI_ARCH (bfd does not correctly identify target).
* config/sparc/tm-sparclite.h: Ditto.
* config/sparc/tm-sun4sol2.h: Define GDB_MULTI_ARCH.
* sparclet-rom.c (sparclet_regnames): Initialize explicitly, to
avoid using deprecated REGISTER_NAMES macro.
* Makefile.in: Let sparc-tdep.c depend on arch-utils.h.
Don't include "bfd-elf.h".
(address_significant_size): Delete variable.
(dwarf2_build_psymtabs_hard): Don't set it, or check for
consistency between it and the Dwarf 2 compilation unit header
address size.
(read_address): Don't mask off bits above

out that these are target-dependent, and useful in non-native
configurations. Moved to...
* i386-linux-tdep.c: ... Here, a new file.
* Makefile.in (ALLDEPFILES): Add i386-linux-tdep.c.
(i386-linux-tdep.o): New rule.
(i386-linux-nat.o): We no longer depend on frame.h.

From Jeff Bailey <jbailey@gnu.org>:
* configure.in: Use AC_CHECK_TOOL to find MiG.
* Makefile.in (MIG): New variable.
* config/i386/i386gnu.mh (MIG): Remove.
* configure: Regenerated.
* configure.in: Remove the addition of sol-thread.c to the
CONFIG_INITS list. This caused problems with init.c, because
sol-thread.c would be grepped twice for _initialize_* functions.
* configure: Ditto.
* Makefile.in: Add FIXME for init.c.
