If you are using the verson of Sqlite in one big file you are expecting a lot from the optimizer. I would never compile Sqlite that way, instead do it the normal way and link the optimized. code. Also make sure you remove the -g option which interferes with some AIX linking.
My experience with IBM's Xlc is that it has a very aggressive optimizer and will produce optimized code of high quality, running on one of my tests 40% better than gcc code. I would not compile large files with it.
