[PATCH] D42151: [Polly][ScopBuilder] Make -polly-stmt-granularity=scalar-indep the default.

Fri Feb 2 21:50:19 PST 2018

Meinersbur updated this revision to Diff 132726.
Meinersbur added a comment.

Instead of adding -polly-stmt-granulairy=bb globally, only add the flag to the tests that need it.

This avoids additional discrepancy between Polly's default settings and neew regression tests.

Many differences stem from statements for cmp instructions being created, but then simplified-away because such statments contain no write.
