Attribute Macro inkwell_internals::llvm_versions
source · #[llvm_versions]Expand description
This macro can be used to specify version constraints for an enum/struct/union or other item which can be decorated with an attribute.
It takes one argument which is any range of major or major.minor LLVM versions.
To use with enum variants or struct fields, you need to decorate the parent item with
the #[llvm_versioned_item] attribute, as this is the hook we need to modify the AST
of those items.
