In order to speed up compile time and to avoid random timeouts we now separately track assumptions and restrictions. In this context assumptions describe parameter valuations we need and restrictions describe parameter valuations we do not allow. During AST generation we create a runtime check for both, whereas the one for the restrictions is negated before a conjunction is build. Except the In-Bounds assumptions we currently only track restrictions. Differential Revision: http://reviews.llvm.org/D17247 llvm-svn: 262328
