When compiling for iOS I am getting:

src/arm/sysv.S:338:Unknown pseudo-op: .fpu
src/arm/sysv.S:338:Rest of line ignored. 1st junk character valued 118 (v).
src/arm/sysv.S:158:Unknown pseudo-op: .ifc
src/arm/sysv.S:158:Rest of line ignored. 1st junk character valued 34 (").

This leads me to believe that the older version of AS that apple ships with doesn't contain .ifc and .fpu.

I don't know ARM assembly, but it these functions could be rewritten to not use these pseudo-ops.

Thanks!
