[cfe-users] objc. __auto_type and nullablility inheritance.
Hi to everyone! I'm integrating __auto_type to project, and I faced with some weird issue. __auto_type doesn't inherit nullability nor ownership qualifiers, so if I write __weak Type* _Nonnull a = f(); __auto_type b = a; b will be just Type*, with strong ownership and __nullability_unspecified specifier. Although, if I'm writing __weak Type* _Nonnull a = f(); __typeof(a) b = a; Everything inherits as expected. So type of b is __weak Type* _Nonnull. I know, __weak and _Nullable doesn't make any sense for one variable declaration, but I think you get the point. Is it ok? Why such decision has been made? Thanks for any clarification.___ cfe-users mailing list cfe-users@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-users
[cfe-users] How to use clang-tidy plugin.
Hi! I need to use clang-tidy as a clang plugin, but can't figure out how to do it. I see ClangTidyPlugin.cpp file, and there is ClangTidyPlugin target, but when I run `make clangTidyPlugin` it produces only libclangTidyPlugin.a, no any dynamic library. Am I doing something wrong? Is it even possible? Thanks for any help. ___ cfe-users mailing list cfe-users@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-users
Re: [cfe-users] How to use clang-tidy plugin.
Hmm, I discovered that it is actually part of libclang. But still, I run $ clang main.c -fsyntax-only -Xclang -load -Xclang /Users/zienag/dev/llvm_trunk/build/lib/libclang.dylib -Xclang -plugin -Xclang clang-tidy And it produces error: error: unable to find plugin 'clang-tidy' :( > On 17 Jan 2017, at 18:12, Alfred Zien via cfe-users > wrote: > > Hi!

Re: [cfe-users] How to use clang-tidy plugin.
Thanks for clarifying! Based on this, as I understand, we can't use any other library (for example ASTMatchers) in plugin that clang doesn't use? > On 19 Jan 2017, at 19:44, Benjamin Kramer wrote: > > I don't think I ever added the build rules to build clang-tidy as a > plugin for use outside of libclang.
