Doh, beat me to it by a minute. Yeah, you see what I mean. :) It would be platform suicide to drop 32-bit code generation. Like many RISC architectures, switching to 64-bit is only done for apps that need it, because it is not free and will not, in general, make apps faster. Anyone who has w

Yeah, I understand why you would believe that. I'm not blaming you, I just want to let everyone know the sentence "32-bit code generation as we use it is no longer supported upstream" is incorrect. You can see on the GCC 4.7 [1] and 4.8 [2] changes list that removing any SPARC code generation featu

Hi, OpenJDK 8 is being packaged [1] and I'm looking for porters willing to try and compile it on other architectures. So far it builds fine on amd64 and some work has started for kFreeBSD. No other architecture has been tested yet, so any help is welcome. Thank you, Emmanuel Bourg [1] http://an
