* mdebugread.c: New file, split out of mipsread.c. Added
elfmdebug_build_psymtabs routine. Added some checks on external
symbols. Changed code to keep ecoff_debug_info and
ecoff_debug_swap structs in the psymtab and in global pointers
rather than retrieving them from the bfd. Also changed to keep
the pending list with the psymtab rather than the objfile (each
psymtab for a single objfile points to the same pending list).

the sym_fns.

REGISTER_CONVERT_TO_RAW, REGISTER_CONVERT_TO_VIRTUAL): Remove
versions for which REGISTER_CONVERTIBLE is always false.
* z8k-tdep.c (register_convert_to_virtual, register_convert_to_raw):
Remove, no longer used.
* alpha-tdep.c (alpha_register_convert_to_raw,
alpha_register_convert_to_virtual): New routines to handle
the different raw formats in alpha floating point registers.
* config/alpha/tm-alpha.h (REGISTER_CONVERTIBLE,
REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Use them.
Use read_memory_nobpt.
(is_delayed, mips_in_lenient_prologue): New functions.

config/mips/tm-mips.h (INVALID_FLOAT): Define to 0 like most machines.
The IEEE_FLOAT code in print_floating takes care of it.
the necessary bits.
* findvar.c (value_from_register): Fix uninitialized first_addr
which caused problems with assignment of doubles to register variables
on some targets.
* mipsread.c: Remove TM_FILE_OVERRIDE, include tm.h and provide the
missing mips definitions if necessary.
Fix handling of double register variables for mips targets and big
endian hosts. These patches are from Paul Flinders <ptf@delcam.co.uk>.
* config/mips/tm-mips.h: Increase MAX_REGISTER_{RAW,VIRTUAL}_SIZE to
8 bytes for doubles.
* config/mips/tm-mips.h (REGISTER_CONVERT_TO_TYPE): New macro for
conversion of type held in multiple registers to host format.
* config/mips/tm-mips.h (REGISTER_CONVERT_FROM_TYPE): New macro,
companion to REGISTER_CONVERT_TO_TYPE.
* config/mips/tm-mips.h (EXTRACT_RETURN_VALUE, STORE_RETURN_VALUE):
Convert to function calls.
* config/mips/tm-mips.h (FIX_CALL_DUMMY): New code for big endian
mips targets.
* mips-tdep.c (mips_print_register): Raw buffer now needs just
MAX_REGISTER_RAW_SIZE bytes.

(if defined) for doubles.
* mips-tdep.c: (mips_extract_return_value, mips_store_return_value):
New functions, take care of REGISTER_CONVERT_TO/FROM_TYPE.

defined.
config files moved to an appropriate config/<cpu> subdirectory.
* nm-*, xm-*, tm-*: All native, host, and target files, which
get linked to nm.h, xm.h, and tm.h respectively by configure,
moved to appropriate config/<cpu> subdirectory.
