This is applied to the vector types defined in <arm_mve.h> for use with the intrinsics for the ARM MVE vector architecture. Its purpose is to inhibit lax vector conversions, but only in the context of overload resolution of the MVE polymorphic intrinsic functions. This solves an ambiguity problem with polymorphic MVE intrinsics that take a vector and a scalar argument: the scalar argument can often have the wrong integer type due to default integer promotions or unsuffixed literals, and therefore, the type of the vector argument should be considered trustworthy when resolving MVE polymorphism. As part of the same change, I've added the new attribute to the declarations generated by the MveEmitter Tablegen backend (and corrected a namespace issue with the other attribute while I was there).

//===----------------------------------------------------------------------===// // 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/
