Hi, I thought I would add these two aliasing testcases which I have in Cavium's private tree for a while now. They both pass since the addition of MEM_REF.
Committed as obvious after a bootstrap and test on x86_64-linux-gnu with no regressions. Thanks, Andrew Pinski 2012-07-21 Andrew Pinski <apin...@cavium.com> * gcc.dg/tree-ssa/alias-21.c: New testcase. * gcc.dg/tree-ssa/alias-22.c: New testcase.
