Hal Finkel 435798e96a Disable unrolling in the loop vectorizer when disabled in the pass manager ... When unrolling is disabled in the pass manager, the loop vectorizer should also not unroll loops. This will allow the -fno-unroll-loops option in Clang to behave as expected (even for vectorizable loops). The loop vectorizer's -force-vector-unroll option will (continue to) override the pass-manager setting (including -force-vector-unroll=0 to force use of the internal auto-selection logic). In order to test this, I added a flag to opt (-disable-loop-unrolling) to force disable unrolling through opt (the analog of -fno-unroll-loops in Clang). Also, this fixes a small bug in opt where the loop vectorizer was enabled only after the pass manager populated the queue of passes (the global_alias.ll test needed a slight update to the RUN line as a result of this fix). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189499 91177308-0d34-0410-b5e6-96231b3b80d8		2013-08-28 18:33:10 +00:00
