Thanks for reviewing. One concern I have going forward is the number of entries that will appear in the switch statement inside addVectorizableFunctionsFromVecLib(). I assume that the right thing to do is to replace this with something that is TableGen'd? Also, I just wanted to point out that some of these entries will result in svml calls that are not legal. E.g., __svml_sinf32 does not actually exist in the library, but can be legalized in case one explicitly sets a vector length of 32. Although these types of cases are probably not common, I wanted to bring this to your attention since the legalization piece of this work will be reviewed and committed separately. If needed, I can remove those entries until the legalization is in place.
