![]() This fixes a serious bug in r240462: checking the BuiltinID for ARM::BI_MoveToCoprocessor* in EmitBuiltinExpr() ignores the fact that each target has an overlapping range of the BuiltinID values. That check can trigger for builtins from other targets, leading to very bad behavior. Part of the reason I did not implement r240462 this way to begin with is the special handling of the last argument for Neon builtins. In this change, I have factored out the check to see which builtins have that extra argument into a new HasExtraNeonArgument() function. There is still some awkwardness in having to check for those builtins in two separate places, i.e., once to see if the extra argument is present and once to generate the appropriate IR, but this seems much cleaner than my previous patch. llvm-svn: 240522 |

//===----------------------------------------------------------------------===// // 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.cs.uiuc.edu/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
