Polly currently does not support irreducible control and it is probably not worth supporting. This patch adds code that checks for irreducible control and refuses regions containing irreducible control. Polly traditionally had rather restrictive checks on the control flow structure which would have refused irregular control, but within the last couple of months most of the control flow restrictions have been removed. As part of this generalization we accidentally allowed irregular control flow. Contributed-by: Karthik Senthil and Ajith Pandel llvm-svn: 258497 |
