It looks like the DeadStoreElimination optimization doesn't work across BasicBlock boundaries. The project I'm working on (https://github.com/trailofbits/mcsema), would tremendously benefit from even simple cross-block DSE.
There was a patch to do non-local DSE few years ago (http://lists.cs.uiuc.edu/pipermail/llvmdev/2010-January/028751.html), but seems that the patch was never merged.
Is there an existing way to do cross-block DSE?
Was there something wrong with the original non-local DSE patch that it wasn't merged?
