I'm afraid you're missing my point. The problem is that for 64-bit and 32-bit floating-point to integer conversion, x86 (32bit) target uses fistp* whereas x86_64 (64-bit) target uses cvt* WHEN -mfpmath=387. This defeats the purpose of the option -mfpmath=387 which is supposed to make floating-point computations to use 387, instead of SSE2. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29337
