New Revision: 230767
URL: http://llvm.org/viewvc/llvm-project?rev=230767&view=rev
Log:
Add verifier to the IslCodeGeneration
After a function was created we will verify it for Debug builds. If
errors are found and debug-type equals "polly-codegen-isl" the SCoP,
the isl AST, the function as well as the errors will be printed.
