I can only guess that you probably mean the Debray alias analysis
proposed at the GCC summit in 2003. Follow this link for the paper:
"http://gcc.fyxm.net/summit/2003/Alias analysis for intermediate code.pdf"
That code was never included because this analysis is *very* expensive,
and it should be possible to propagate even better alias analysis info
down from the tree optimizers to RTL.
