Support for collecting and supplying general purpose and floating
point registers is provided along with signal frame unwinding. While
FreeBSD/arm kernels do populate NT_FPREGSET notes, they are always
zero-filled, so this implementation ignores them. Recent FreeBSD/arm
kernels generate NT_ARM_VFP notes which are used to supply
floating-point registers. As with Linux, the AT_HWCAP feature flags
are used to determine the correct target description.
