Re: -funroll-loops experimental in gcc-3.3.2
Hello,
> I understood -funroll-loops is experimental in gcc-3.3.2.
no, gcc 3.3 still uses the old unroller. The new unroller that could be
called experimental will be in 3.4. Experimental here means that it is a new
piece of code and it is probable that it will cause some problems, won't
work properly on the more exotic architectures, etc.
What I said above is not actually the whole truth. Some of the linux
distributions do not use the compiler from 3.3 branch, but rather the
one from hammer-3_3-branch which includes additional experimental
features, for example the new unroller.
