A recent commit introduced the use of [[maybe_unused]] following
LLVM_PREFFERED_TYPE(bool) on a member variable declaration. I compiled
it with clang 14.0, which doesn't support the `preferred_type` attribute
so I didn't notice a problem. However, starting with clang 18.0, this
reports an error ("an attribute list cannot appear here") because of the
mixing of attribute styles.
This change fixes the problem by replacing [[maybe_unused]] with
LLVM_ATTRIBUTE_UNUSED.
C language Family Front-end
Welcome to Clang.
This is a compiler front-end for the C family of languages (C, 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 websites. Here are some pointers:
