   3 /* Internally, we suppress any use of exception or rounding other
   4    than what is supported by the hardware.  This does mean that some
   5    code will silently fail to report exceptions, set rounding mode
   6    as expected, etc., but it allows math code to compile that otherwise
   7    wouldn't (such as math/s_fma.c) and so is valuable.
   8
   9    We intentionally ignore the "exception" arguments of functions that
  10    take an exception, since we can't even evaluate the argument
  11    without causing a build failure.  The extra level of statement
  12    expression wrapping avoids "statement with no effect" warnings.
  13    Since the callers don't check for errors anyway, we just claim
  14    success in every case.
  15
  16    The overrides for libc_ functions must happen before we include
  17    the generic math_private.h, and the overrides for regular
  18    <fenv.h> functions must happen afterwards, to avoid clashing with
  19    the declarations of those functions.  */
