We have many warnings on GOROOT.
Many (most) of them look like false-positives.
It's better to constrain floatCompare to be less greedy (or this should be controlled by config).

For example, comparison with zero usually makes sense, same goes for Inf and self-comparison like x == x or x != x (the latter is NaN check).

We may also want to skip simple v != literal and v == literal unless v is a expression, not just a var:

v != 5.0 // OK
foo() != -1.0 // OK? Maybe function documents that it sometimes returns -1.0
x + y != 5.0 // suspicious
x*2 - y != 5.0 // suspicious
// and so on...
