Hi Sebastian,

Your commit introduced this test-suite failure:

http://lab.llvm.org:8011/builders/clang-cmake-aarch64-quick/builds/11121

/home/buildslave/buildslave/clang-cmake-aarch64-quick/test/test-suite/SingleSource/Benchmarks/Polybench/linear-algebra/kernels/mvt/mvt.c:117:25:
error: use of undeclared identifier 'FP_ABSTOLERANCE'
  double AbsTolerance = FP_ABSTOLERANCE;
                        ^

Missing a header?

cheers,
