           Summary: gcc/config/i386/i386-options.cc:3039:8: warning:

Source code is

  if (ix86_tune_features [X86_TUNE_AVOID_256FMA_CHAINS])
    SET_OPTION_IF_UNSET (opts, opts_set, param_avoid_fma_max_bits, 512);
  else if (ix86_tune_features [X86_TUNE_AVOID_256FMA_CHAINS])
    SET_OPTION_IF_UNSET (opts, opts_set, param_avoid_fma_max_bits, 256);
  else if (ix86_tune_features [X86_TUNE_AVOID_128FMA_CHAINS])
    SET_OPTION_IF_UNSET (opts, opts_set, param_avoid_fma_max_bits, 128);

Suggest code rework.=20

I got this by adding -Wduplicated-cond to a build.

If someone were brave enough to add this warning flag to -Wall, then
other developers could benefit from a well hidden but useful flag.=
