Daniel Jacobowitz ff6f572f8b * arm-tdep.c (arm_scan_prologue): Do not record FPA register saves
if there are no FPA registers.
	(arm_dwarf_reg_to_regnum): New function.
	(arm_register_type, arm_register_name): Return minimal values for
	unsupported registers.
	(arm_register_sim_regno): Handle iWMMXt registers.
	(arm_gdbarch_init): Record missing FPA registers if indicated by
	a target description.  Recognize iWMMXt registers.  Only register
	"info float" for FPA.  Use ARM_NUM_REGS.  Register
	arm_dwarf_reg_to_regnum.
	* arm-tdep.h (enum gdb_regnum): Add ARM_NUM_REGS and iWMMXt
	constants.
	(struct gdbarch_tdep): Add have_fpa_registers.
	* features/xscale-iwmmxt.xml: Update capitalization.
	* regformats/arm-with-iwmmxt.dat: Regenerated.

	* src/gdb/doc/gdb.texinfo (Standard Target Features): Mention
	case insensitivity.
	(ARM Features): Describe org.gnu.gdb.xscale.iwmmxt.

	* gdb.arch/iwmmxt-regs.c, gdb.arch/iwmmxt-regs.exp: Update
	register capitalization.
