Half-precision (16-bit) floating-point support is an optional extension to VFPv3. It can now be enabled when VFPv3 is present and is automatically enabled when VFPv4 is supported. This adds the ability to make GCC's default FPU setting neon-fp16.
The oldest webOS systems use ARM Cortex-A9 CPUs with NEON and FP16 support. Therefore, it should be safe to enable this for the webOS toolchain. Support for NEON/FP16 can be disabled by explicitly passing -mfpu on the GCC command line. The old behavior can be restored with -mfpu=vfpv3.
