Browse Source 
(tdesc_named_type): Use it.
	(tdesc_type_id, maint_print_c_tdesc_cmd): New functions.
	(_intialize_target_descriptions): Register "maint print c-tdesc".
	* features/Makefile (XMLTOC, CFILES, GDB): New macros.
	(cfiles, %.c): New rules.
	* features/arm-with-iwmmxt.c, features/mips-linux.c,
	features/mips64-linux.c: New generated files.

	"xml-support.h".
	(super_xfer_partial, arm_linux_xfer_partial): Remove.
	(arm_linux_read_description): New function.
	(_initialize_arm_linux_nat): Set to_read_description instead of
	to_xfer_partial.  Initialize preparsed description.
	* config/arm/linux.mh (TDEP_XML): Delete.
	* mips-linux-nat.c: Include preparsed descriptions instead of
	"xml-support.h".
	(super_xfer_partial, mips_linux_xfer_partial): Remove.
