Subject: [openrisc] gcc-3.2.3 bugs after merge
Hi All !I think having so many different compilers is causing a little bit of mess.
Anyone disagrees if older versions of gcc are removed from opencores cvs?
(maybe not removed but at least moved to some special directory obsolete),
I'm thinking versions OC 2.95.2 and OC 3.1 should be (re)moved and OC 3.2.3
should become the official version. We also have to merge the UC version.
regards,
Damjan
