2010-02-10  H.J. Lu  <hongjiu.lu@intel.com>

	* target-descriptions.c (tdesc_type): Add TDESC_TYPE_I387_EXT,
	TDESC_TYPE_I386_EFLAGS and TDESC_TYPE_I386_MXCSR.
	(tdesc_predefined_types): Add i387_ext, i386_eflags and
	i386_mxcsr.
	(tdesc_find_type): New.
	(tdesc_gdb_type): Use tdesc_find_type.  Handle TDESC_TYPE_I387_EXT,
	TDESC_TYPE_I386_EFLAGS and TDESC_TYPE_I386_MXCSR.

	* target-descriptions.h (tdesc_find_type): New.
