* NEWS: Mention ARM VFP support.
* target-descriptions.c (tdesc_register_type): Make public.
(tdesc_unnumbered_register): New function.
(tdesc_register_reggroup_p): Allow missing
pseudo_register_reggroup_p.
* target-descriptions.h (tdesc_register_type): Declare.
(tdesc_unnumbered_register): Declare.
* arm-tdep.c (arm_neon_quad_read, arm_neon_quad_write): New functions.
(arm_push_dummy_call): Use arm_neon_quad_write.
(arm_neon_double_type, arm_neon_quad_type): New functions.
(arm_register_type): Handle VFP and NEON registers. Override the
types of double-precision registers for NEON. Disable FPA registers
if they are not present.
(arm_dwarf_reg_to_regnum): Add current VFP and NEON register numbers.
(arm_return_value): Use arm_neon_quad_write and arm_neon_quad_read.
(arm_register_name): Handle VFP single and NEON quad registers.
(arm_pseudo_read, arm_pseudo_write): New functions.
(arm_gdbarch_init): Check for VFP and NEON in the target description.
Assign numbers to double-precision registers. Register VFP and NEON
pseudo registers. Remove a shadowed "i" variable.
* arm-tdep.h (enum gdb_regnum): Add ARM_D0_REGNUM and
ARM_D31_REGNUM.
(struct gdbarch_tdep): Add have_neon_pseudos, have_neon,
have_vfp_registers, have_vfp_pseudos, neon_double_type,
and neon_quad_type.
* features/Makefile: Make expedite settings only architecture
specific.
(WHICH): Add new ARM descriptions.
* features/arm-with-neon.xml, features/arm-with-vfpv2.c,
features/arm-with-vfpv3.c, features/arm-vfpv2.xml,

features/arm-with-vfpv3.xml, features/arm-with-neon.c: New files.
* regformats/arm-with-neon.dat, regformats/arm-with-vfpv2.dat,
regformats/arm-with-vfpv3.dat: Generate.
doc/
* gdb.texinfo (ARM Features): Document org.gnu.gdb.arm.vfp and
org.gnu.gdb.arm.neon.
gdbserver/
* linux-low.c (linux_write_memory): Update debugging output.
* Makefile.in (clean): Add new descriptions.
(arm-with-vfpv2.o, arm-with-vfpv2.c, arm-with-vfpv3.o)
(arm-with-vfpv3.c, arm-with-neon.o, arm-with-neon.c): New rules.
* configure.srv: Add new files for arm*-*-linux*.
* linux-arm-low.c: Add new declarations.
(PTRACE_GETVFPREGS, PTRACE_SETVFPREGS): Define if undefined.
(arm_hwcap, HWCAP_VFP, HWCAP_IWMMXT, HWCAP_NEON, HWCAP_VFPv3)
(HWCAP_VFPv3D16): New.
(arm_fill_wmmxregset, arm_store_wmmxregset): Check HWCAP_IWMMXT
instead of __IWMMXT__.
(arm_fill_vfpregset, arm_store_vfpregset, arm_get_hwcap)
(arm_arch_setup): New.
(target_regsets): Remove #ifdef. Add VFP regset.
(the_low_target): Use arm_arch_setup.
