* LoopVectorizer: Handle strided memory accesses by versioningArnold Schwaighofer2014-01-101-0/+50
for (i = 0; i < N; ++i) A[i * Stride1] += B[i * Stride2]; We take loops like this and check that the symbolic strides 'Strided1/2' are one and drop to the scalar loop if they are not. This is currently disabled by default and hidden behind the flag 'enable-mem-access-versioning'. radar://13075509 llvm-svn: 198950
