Make our `DIFlags` match `LLVMDIFlags` in the LLVM-C API In order to be able to use a mixture of LLVM-C and C++ bindings for debuginfo, our Rust-side `DIFlags` needs to have the same layout as LLVM-C's `LLVMDIFlags`, and we also need to be able to convert it to the `DIFlags` accepted by LLVM's C++ API. Internally, LLVM converts between the two types with a simple cast. We can't necessarily rely on that always being true, and LLVM doesn't expose a conversion function, so we have two potential options: - Convert each bit/subvalue individually - Statically assert that doing a cast is actually fine As long as both types do remain the same under the hood (which seems likely), the static-assert-and-cast approach is easier and faster. If the static assertions ever start failing against some future version of LLVM, we'll have to switch over to the convert-each-subvalue approach, which is a bit more error-prone. --- Extracted from #134009, though this PR ended up choosing the static-assert-and-cast approach over the convert-each-subvalue approach. |
