[LLVMdev] Loop-specific optimizations

That definitely sounds interesting. Do you add these attributes to the
bytecode, or how does opt decide which transformations to apply? This
because our approach, attaching metadata to loop latches, is quite
fragile; loop latches can easily get destroyed or transformed during
optimization.

Sadly no, I missed the call for participation. Are the talks going to be
videotaped, or will proceedings be published? Or could you, if possible,
send over a working paper or something similar?
