The added test case was triggering assertion > Assertion failed: (!SpecializedTemplate.is<SpecializedPartialSpecialization*>() && "Already set to a class template partial specialization!"), function setInstantiationOf, file clang/include/clang/AST/DeclTemplate.h, line 1825. It was happening with ClassTemplateSpecializationDecl `enable_if_not_same<int, int>`. Because this template is specialized for equal types not to have a definition, it wasn't instantiated and its specialization kind remained TSK_Undeclared. And because it was implicit instantiation, we didn't mark the decl as invalid. So when we try to find the best matching partial specialization the second time, we hit the assertion as partial specialization is already set. Fix by reusing stored partial specialization when available, instead of looking for the best match every time. rdar://problem/39524996 Reviewers: rsmith, arphaman Reviewed By: rsmith Subscribers: cfe-commits Differential Revision: https://reviews.llvm.org/D46909 llvm-svn: 332509 |

//===----------------------------------------------------------------------===// // C Language Family Front-end //===----------------------------------------------------------------------===// Welcome to Clang. This is a compiler front-end for the C family of languages (C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM compiler infrastructure project. Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source-level tools. One example of this is the Clang Static Analyzer. If you're interested in more (including how to build Clang) it is best to read the relevant web sites. Here are some pointers: Information on Clang: http://clang.llvm.org/ Building and using Clang: http://clang.llvm.org/get_started.html Clang Static Analyzer: http://clang-analyzer.llvm.org/ Information on the LLVM project: http://llvm.org/ If you have questions or comments about Clang, a great place to discuss them is on the Clang development mailing list: http://lists.llvm.org/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
