* 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-vfpv3.xml, features/arm-with-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. testsuite/ * gdb.base/float.exp: Handle VFP registers.
