Michael Kruse afd2db5351 [SCEVValidator] Fix loop exit values considered affine. Index calculations can use the last value that come out of a loop. Ideally, ScalarEvolution can compute that exit value directly without depending on the loop induction variable, but not in all cases. This changes isAffine to not consider such loop exit values as affine to avoid that SCEVExpander adds uses of the original loop induction variable. This fix is analogous to r262404 that applies to general uses of loop exit values instead of index expressions and loop bouds as in this patch. This reduces the number of LNT test-suite fails with -polly-position=before-vectorizer -polly-unprofitable from 10 to 8. llvm-svn: 262665		2016-03-03 22:10:52 +00:00
