[Insight-developers] ITK 3.14 cannot build with GCC on non-ix86 (due to Rounding code) vnl_math_rnd_halfinttoeven

[Luis Ibanez]

Hi Steve,

Thanks for pointing this out.

This seems to indicate that some TRY_COMPILE and TRY_RUN
tests from VNL are not being executed correctly in these
platforms.

We will have to track where in the code we are testing for

          VNL_CHECK_FPU_ROUNDING_MODE

The test may be improper for that architecture, or it may
not be executed correctly there.


------

inline int vnl_math_rnd_halfinttoeven(double  x)
{
# ifdef VNL_CHECK_FPU_ROUNDING_MODE
   assert(fegetround()==FE_TONEAREST);
# endif
   int r;
   __asm__ __volatile__ ("fistpl %0" : "=m"(r) : "t"(x) : "st");
   return r;
}

------------


   Luis
