* Rename getMaximumUnrollFactor -> getMaxInterleaveFactor; also rename option ↵Sanjay Patel2014-09-101-2/+2
| | | | | | | | | | | names controlling this variable. "Unroll" is not the appropriate name for this variable. Clang already uses the term "interleave" in pragmas and metadata for this. Differential Revision: http://reviews.llvm.org/D5066 llvm-svn: 217528

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This should hopefully have fixed the stage2/stage3 miscompare on the dragonegg testers. "LoopVectorize: Use the dependence test utility class We now no longer need alias analysis - the cases that alias analysis would handle are now handled as accesses with a large dependence distance. We can now vectorize loops with simple constant dependence distances. for (i = 8; i < 256; ++i) { a[i] = a[i+4] * a[i+8]; } for (i = 8; i < 256; ++i) { a[i] = a[i-4] * a[i-8]; } We would be able to vectorize about 200 more loops (in many cases the cost model instructs us no to) in the test suite now. Results on x86-64 are a wash. I have seen one degradation in ammp. Interestingly, the function in which we now vectorize a loop is never executed so we probably see some instruction cache effects. There is a 2% improvement in h264ref. There is one or the other TSCV loop kernel that speeds up. radar://13681598" llvm-svn: 184724
