gcc/
* doc/extend.texi (Half-Precision): Update wording to reflect
that there are now multiple -mfpu options that enable fp16
hardware support.
* doc/invoke.texi: Update list of ARM -mfpu= options.
* config.gcc: Update ARM --with-fpu option list.
* config/arm/arm.c (all_fpus): Add vfpv3-fp16, vfpv3-d16-fp16,
vfpv3xd and vfpv3xd-fp16.
(use_vfp_abi): New function.
(aapcs_vfp_is_call_or_return_candidate): Avoid double precision regs
when undesirable.
(aapcs_vfp_is_return_candidate, aapcs_vfp_is_call_candidate,
aapcs_vfp_allocate_return_reg): Use use_vfp_abi.
(arm_rtx_costs_1, arm_size_rtx_costs, arm_fastmul_rtx_costs,
arm_9e_rtx_costs): Only expect double-precision operations if the FPU
provides them.
(coproc_secondary_reload_class): Reload HFmode via GENERAL_REGS if no
NEON.
(arm_print_operand): Handle 'p' modifier.
(arm_hard_regno_mode_ok): : Allow HFmode in VFP registers if
TARGET_FP16.
* config/arm/arm.h (TARGET_VFP_SINGLE, TARGET_VFP_DOUBLE): Define.
(TARGET_FP16): Define.
* config/arm/vfp.md: Disable double-precision patterns if the FPU
does not provide them.
(arm_movdi_vfp, thumb2_movdi_vfp): Use fcpys to move
double-precision values on a single-precision FPU.
(movdf_vfp, thumb2_movdf_vfp): Likewise. Use "Dy" for
double-precision constants.
(movhf_vfp_neon): New pattern (was movhf_vfp).
(movhf_vfp): Remove NEON instructions.
* config/arm/constraints.md: Add new "Dy" constraint for
double-precision constants. Update description of "Dv".
* config/arm/arm.md: Disable double-precision patterns if the FPU
does not provide them
