Hello, it it possible to get a kind of diagnostics if the variable is totally optimized away? For example, in: void foo (struct some_type *obj) { ... some code where 'obj' is not used ... bar (obj->some_member); ... some code where 'obj' is not used again ... baz (obj->some_member); } 'obj' is likely to be optimized away so only

Hello Hal, I have a strong suspicion that your constant folding optimization introduced at r174746 is broken on ARM. There is a bug about it: http://llvm.org/bugs/show_bug.cgi?id=15581 There is no such issue with 3.2, and reverting r174746 on top of r178740 also fixes the problem. I'm trying to fix it myself, but still have no good ideas; so it would be great to have an advice from you.

Hello all, can someone do a quick review of the one-line proposal fix attached to http://llvm.org/bugs/show_bug.cgi?id=15581? I'm not sure that I can explain why it works, but it (hopefully) is, so I really need a feedback with this. Thanks, Dmitry
