Re: [Open64-devel] Getting rid of GCC 3.* from open64?

Steve: What is the time frame you are looking at for the proposed
removal of the old versions of the GCC frontend ? I assume you are
looking at doing that after the upcoming 4.2.3 release.

It is not typical for a given version of a compiler to support
multiple versions of a frontend. People needing the older
version of a frontend stay with the older version of the whole
compiler.

As new optimizer changes are checked into the Open64 trunk, I would
suspect there is no testing being done with the older frontends. There
are likely  defects that the users of the older frontends would have to
find and fix on their own.

I would suggest setting a target date for removing the old frontends in
the Open64.net trunk, taking into consideration the transition plans of the
various groups. Beyond that target date, groups needing the older version
of the frontends can continue to use the 4.2.3 version of Open64.
