Ira Rosen <irar at il dot ibm.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |irar at il dot ibm.com --- Comment #1 from Ira Rosen <irar at il dot ibm.com> 2010-10-17 13:22:18 UTC --- This code requires SLP to originate from loads, which seems to be a bit more complicated than the currently implemented use-def scan (it will also need to reduce/extract scalars from the vectors in the end of vector computation). I don't see any major obstacles for this, however, currently I don't plan to work on this. Another required feature is to work on groups bigger than vectorization factor, i.e., combining 2 statements in this example and leaving the 3rd one scalar. Ira
