* config/arm/arm.c (arm_output_fldmx): Output FLDMD instead of
FLDMX. Rename function to...
(vfp_output_fldmd): ...this.
(vfp_output_fstmx): Output FSTMD instead of FSTMX. Rename
function to...
(vfp_output_fstmd): ...this.
(vfp_emit_fstmx): Don't leave space in the frame layout for the
FSTMX format word. Rename function to...
(vfp_emit_fstmd): ...this.
(arm_get_vfp_saved_size): Don't add in space for the FSTMX format
word.
(arm_output_epilogue): Adjust comment to reflect use of FSTMD.
(arm_unwind_emit_sequence): Don't compensate for the FSTMX format
word. Also emit "vsave" assembler directives in such cases rather
than "save".
* config/arm/libunwind.S (gnu_Unwind_Restore_VFP,
gnu_Unwind_Save_VFP): Adjust comments.
(gnu_Unwind_Restore_VFP_D, gnu_Unwind_Save_VFP_D): New functions
for saving and restoring using FSTMD and FLDMD rather than
FSTMX and FLDMX.
(gnu_Unwind_Restore_VFP_D_16_to_31, gnu_Unwind_Restore_VFP_D_16_to_31):
New functions for saving and restoring the VFPv3 registers 16 .. 31.
* config/arm/pr-support.c (gnu_unwind_execute): Add conditional
compilation case to correctly handle unwind opcode 0xc8 when using
VFP.
* config/arm/unwind-arm.c (struct vfpv3_regs): New.
(DEMAND_SAVE_VFP_D, DEMAND_SAVE_VFP_V3): New flags.
(__gnu_Unwind_Save_VFP_D, __gnu_Unwind_Restore_VFP_D,
__gnu_Unwind_Save_VFP_D_16_to_31, __gnu_Unwind_Restore_VFP_D_16_to_31):
Declare.
(restore_non_core_regs): Restore registers using FLDMD rather than
FLDMX if required. Also handle restoration of VFPv3 registers.
(_Unwind_VRS_Pop): Handle saving and restoring of registers using
FSTMD and FLDMD if required; also handle VFPv3 registers 16 .. 31,
including cases where the caller specifies a range of registers
that overlaps the d15/d16 boundary.
