Re: [arm-gnu] _FPU_EXTENDED and _FPU_DOUBLE

[Meng Sun <meng.sun@xxxxxxxxx>]

Hi,

still this problem. I find a solution:

#ifdef _FPU_IEEE
#  ifndef *_FPU_EXTENDED* /* e.g., *ARM* processor under Linux */
#  define *_FPU_EXTENDED* 0
#  endif
#endif

#ifndef _FPU_DOUBLE
#  define _FPU_DOUBLE 0
#endif

Is that a good option?

Cheers,
