The test fails for me with:

sorry, unimplemented: -mfloat-abi=hard and VFP
compiler exited with status 1
Does one have to pass -mfloat-abi= option too unconditionally?
Can somebody from the ARM/Linaro people handle this?
Since, this testcase came from the kernel, you could compile this soft /
softfp to make the problem go away and that would be quite reasonable.
Attached is what I've applied to trunk after
1. testing cross arm-none-eabi with a hardfp multilib - hardfp multilib
marks as unsupported but softfp passes.
2. testing native hardfp which is default on distros, test passes.
Given there are enough autotesters that do these 2 variations we'll
catch failures if any with this testcase.

This asm looks quite bogus, and with
asm ("");
it ICEs the same way, can it be changed?
