Could you please post a patch with suggested wording about this
option (I was trying to write something similar to the warning that
icc has in its documentation about precision settings).
How about this? It perhaps reflects my own biases, but the term
"catastrophic loss of accuracy" is sometimes used in the technical
sense that I mean here. For the performance figures, I used the
figures you gave in your e-mail but add "or more" to be on the safe side.
What about "significant loss of accuracy" as these options probably
won't cause a nuclear reactor meltdown ;)
