[gmx-developers] compilation issue with icc 11 on 64 bit with sse2 optimization

[Michael Shirts]

Hi, guys-

Compiling with intel 11 compiler in 64 bit, with sse2 optimizations
enabled, I get errors like:

genborn_sse2_double.c(72): error: cast to type "__m128d" is not allowed
      __m128d signbit           = (__m128d)
_mm_set1_epi64x(0x8000000000000000ULL);

The question is, is this a bug, or with intel compilers is automatic
sse2 optimization good enough that it can be disabled when using intel
compilers?

Thanks,
