tests: Drop -polly-detect-unprofitable and -polly-no-early-exit These flags are now always passed to all tests and need to be disabled if not needed. Disabling these flags, rather than passing them to almost all tests, significantly simplfies our RUN: lines. llvm-svn: 249422

Allow multiple reductions per statement Iterate over all store memory accesses and check for valid binary reduction candidate loads by following the operands of the stored value. For each candidate pair we check if they have the same base address and there are no other accesses which may overlap with them. This ensures that no intermediate value can escape into other memory locations or is overwritten at some point. + 17 test cases for reduction detection and reduction dependency modeling llvm-svn: 211957

Introduce reduction types This change is particularly useful in the code generation as we need to know which binary operator/identity element we need to combine/initialize the privatization locations. + Print the reduction type for each memory access + Adjusted the test cases to comply with the new output format and to test for the right reduction type llvm-svn: 212126
