[cfe-users] (bug?) ParsedAttr::getNumArgs() always return zero
Dear colleguaes, it seems i have met the bug for processing of C++11 custom language attributes. 1) I took example from https://github.com/llvm/llvm-project/blob/main/clang/examples/Attribute/Attribute.cpp2) And make a short sample which reproduce the bug https://github.com/FROL256/clang_parse_ast_example The problem in that getNumArgs() is always zero, nevermind how many arguments we actually have in the attribute.I have tested this with clang 12. I think i could test it under clang 14 if build sample as a part of llvm.But probably i just did some-thing wrong ... ? Anyway it would be nice to have this issue working with clang 12 because usually i work with prebuild packages of clang and libtooling on Linux Mint.Could you please look prepared sample and suggest sms if possible ... thanks! )-- Best Regards, Frolov V.A. ___ cfe-users mailing list cfe-users@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-users

I'm /guessing/ this API doesn't respond with attributes clang doesn't recognize (CC'd Aaron Ballman who would likely know the details better than I do). Does the API correctly respond with a non-zero number of attributes for any clang-supported attribute (listed here: https://clang.llvm.org/docs/AttributeReference.html ) On Thu, Dec 2, 2021 at 5:23 AM Владимир Фролов via cfe-users < cfe-users@lists.llvm.org> wrote: > Dear colleguaes, it seems i have met the bug for processing of C++11 > custom language attributes. > > 1) I took example from > https://github.com/llvm/llvm-project/blob/main/clang/examples/Attribute/Attribute.cpp > 2) And make a short sample which reproduce the bug > https://github.com/FROL256/clang_parse_ast_example > > The problem in that getNumArgs() is always zero, nevermind how many > arguments we actually have in the attribute. > I have tested this with clang 12.
