Call math_opt_barrier inside if
Since floating-point operation may trigger floating-point exceptions, we call math_opt_barrier inside if to prevent code motion. [BZ #19465] * sysdeps/ieee754/dbl-64/s_fma.c (__fma): Call math_opt_barrier inside if. * sysdeps/ieee754/ldbl-128/s_fmal.c (__fmal): Likewise. * sysdeps/ieee754/ldbl-96/s_fma.c (__fma): Likewise. * sysdeps/ieee754/ldbl-96/s_fmal.c (__fmal): Likewise.
