    lib/msun/src         s_fma.c s_fmal.c 
  Log:
  Fix some corner cases:
  - fma(x, y, z) returns z, not NaN, if z is infinite, x and y are finite,
    x*y overflows, and x*y and z have opposite signs.
  - fma(x, y, z) doesn't generate an overflow, underflow, or inexact exception
    if z is NaN or infinite, as per IEEE 754R.
  - If the rounding mode is set to FE_DOWNWARD, fma(1.0, 0.0, -0.0) is -0.0,
    not +0.0.
