gchatelet added a comment. Actually there's an issue with the code. It doesn't compile in shared_library mode.
ld.lld: error: undefined symbol: clang::Sema::MaximumAlignment >>> referenced by SemaChecking.cpp:5397 (/redacted/llvm-project/clang/lib/Sema/SemaChecking.cpp:5397) >>> tools/clang/lib/Sema/CMakeFiles/obj.clangSema.dir/SemaChecking.cpp.o:(clang::Sema::SemaBuiltinAssumeAligned(clang::CallExpr*)) >>> referenced by SemaChecking.cpp:3670 (/redacted/llvm-project/clang/lib/Sema/SemaChecking.cpp:3670) >>> tools/clang/lib/Sema/CMakeFiles/obj.clangSema.dir/SemaChecking.cpp.o:(clang::Sema::checkCall(clang::NamedDecl*, clang::FunctionProtoType const*, clang::Expr const*, llvm::ArrayRef<clang::Expr const*>, bool, clang::SourceLocation, clang::SourceRange, clang::Sema::VariadicCallType)) >>> referenced by SemaDeclAttr.cpp:1631 (/redacted/llvm-project/clang/lib/Sema/SemaDeclAttr.cpp:1631) >>> tools/clang/lib/Sema/CMakeFiles/obj.clangSema.dir/SemaDeclAttr.cpp.o:(clang::Sema::AddAssumeAlignedAttr(clang::Decl*, clang::AttributeCommonInfo const&, clang::Expr*, clang::Expr*)) It comes from the fact that `Diag::operator<<` takes arguments by `const&`. You'd need to anchor the value in `Sema.cpp` but then the compiler doesn't see the value anymore, another option would be to use inlined variables <https://en.cppreference.com/w/cpp/language/inline> (but this is C++17) or use an anonymous enum value. enum { MaxAlignmentExponent = 29; MaximumAlignment = 1u << MaxAlignmentExponent; }; Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D72998/new/ https://reviews.llvm.org/D72998 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
