Subject: 	* target-descriptions.c (tdesc_predefined_types): New. 
 (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.

	* arm-linux-nat.c: Include preparsed description instead of
	"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.
	(mips_linux_read_description): New function.
	(_initialize_mips_linux_nat): Set to_read_description instead of
	to_xfer_partial.  Initialize preparsed description.
	* config/mips/linux.mh (TDEP_XML): Delete.
	* Makefile.in (XMLFILES): Remove $(TDEP_XML).
	(features_headers, arm_with_iwmmxt_c, mips_linux_c)
	(mips64_linux_c): New macros.
	(arm-linux-nat.o, mips-linux-nat.o): Update.

	* gdb.texinfo (Maintenance Commands): Document "maint print c-tdesc".
