PSLP: Padded SLP Automatic Vectorization
...subsumes PSLP or whether there are areas where PSLP still works (or worked) better, given the (brief) comparison in the paper (from which it seems like it addresses the problem possibly in a more general manner): "The widely used bottom-up SLP algorithm has been improved in several ways. Porpodas et al. [32] propose PSLP, a technique that pads the scalar code with redundant instructions, to convert non-isomorphic instruction sequences into isomorphic ones, thus extending the applicability of SLP. Just like VW-SLP-S, PSLP can vectorize code when some of the lanes differ, but it is most...

PSLP: Padded SLP Automatic Vectorization
Hey, I noticed this talk from the EuroLLVM 2015 (https://llvm.org/devmtg/2015-04/slides/pslp_slides_EUROLLVM2015.pdf) on the PSLP vectorization algorithm (CGO 2015 paper: http://vporpo.me/papers/pslp_cgo2015.pdf). Is anyone working on implementing it? If so, are there Phab reviews I can subscribe to? Best, Matt
