As the load instructions usually have long latency, so do it need some extra
restrict when we try this transformation?

--- Comment #4 from Andrew Pinski ---
The C++ standard defines fma as doing (a*b) + c in infinite precision (and then
round), this is why GCC cannot inline if your target does not have a FMA
instruction.
There is still no bug here.

fmaf80_manually, fmaf64_manually, and fmaf32_manually are not exactly fma.
at least for x86-64-v2 due not doing the add before the rounding of the
multiply.

Note GCC does this optimization at the gimple level some of the times when it
comes to the same type.
Witness:
int x (int t)
{
if (t & 256)
return -26;
return 0;
}

The workaround is
