3896 # precision than what's specified in the source and doing so
3897 # is more efficient than constantly rounding up to 64-bit or
3898 # 32-bit precision as specified in the source, the compiler,
3899 # especially in the optimized mode, tries very hard to keep
3900 # values in x87 floating-point stack (in 80-bit precision)
3901 # as long as possible. This has important side effects, that
3902 # the real value used in computation may change depending on
3903 # how the compiler did the optimization - that is, the value
3904 # kept in 80-bit is different than the value rounded down to
3905 # 64-bit or 32-bit. There are possible compiler options to
3906 # make this behavior consistent (e.g. -ffloat-store would keep
3907 # all floating-values in the memory, thus force them to be
3908 # rounded to its original precision) but they have significant
3909 # runtime performance penalty.
3911 # -mfpmath=sse -msse2 makes the compiler use SSE instructions
3912 # which keep floating-point values in SSE registers in its
3913 # native precision (32-bit for single precision, and 64-bit
3914 # for double precision values). This means the floating-point
3915 # value used during computation does not change depending on
3916 # how the compiler optimized the code, since the value is
3917 # always kept in its specified precision.
