Hi,

It seems gcc.target/arm/armv8_2-fp16-scalar-2.c needs an armhf target
to pass: it wants 4 fmov.f16, but there are only 2 on
arm-linux-gnueabi for instance.

Since the test includes arm_fp16.h, adding -mfloat-abi=hard implies
the usual problem of missing gnu/stubs-hard.h, so it seems to me that
the easiest way is just to skip this test on non-hf targets.

Is this simple patch OK or do we want something smarter?

Thanks,

Christophe

	* gcc.target/arm/armv8_2-fp16-scalar-2.c: Require arm_hf_eabi.
