That might be exactly the empty set of patches, as I did not yet post
any for functions that might return with excess precision.

Be advised that I found bugs in my patches, so given that no one so far
has pointed them out on the mailing list indicates that either nobody
bothered to review, or people are keeping the findings to themselves.

I think fixing excess precision in inverse trig functions might be
easier than removing the asm entirely.
