Dragonegg generates most function parameters as pointers to the actual parameters. However, it does not mark these parameters with the dereferencable attribute. Polly is conservative when it comes to invariant load hoisting, thus we add runtime checks to invariant load hoisted pointers when we do not know that pointers are dereferencable. This is correct behaviour, but is a performance penalty. Add a flag that allows all pointer parameters to be dereferencable. That way, polly can speculatively load-hoist paramters to functions without runtime checks. Differential Revision: https://reviews.llvm.org/D36461 llvm-svn: 311329
