gmp-bugs Digest, Vol 104, Issue 7

[Jay K]

These warnings aren't clearly harmless.
gmp is using very specific syntax to get very specific behavior,
and it is being ignored.




gcc builds all of gmp and then uses very little of it.

And then there is mpfr and mpc, which, granted, aren't very large.
We use gcc as a backend but we don't feed it any of the
"builtins" that it has mpfr and mpc to optimize. Granted, gmp isn't
just for "builtins", so it is more "needed". If you remove just a few
optimizations from gcc though, gmp isn't used then either.
I did that, and so can use the gcc backend without gmp, mpfr, mpc.




Anyway, I'm working on a new backend and very far along.
It is working but I'm making it better still.
