Sorry if I seemed too rude to ask these questions here... 1. The `debuginfo.rs` seems already implemented some LLVM debugging symbols outputting functions, like `create_vec` or `create_local_var`. But currently I can only find `create_local_var` already been used in other components, and others are missing.
So, should the first step be generating LLVM debugging information in every language unit while compiling them ? 2. The Rust compiler owns the `-Z extra-debug-info` option, but it didn't work and seems related to the not yet implemented debugging symbol feature. Is this option created for outputting all language units' LLVM debugging information ? Or it's expected to do more things than this ? 3. I've did some researching works on Rustc and LLVM debugging symbol features, and will start to try to add those outputting function in other components. Is any other step should I take to prepare the project ? Greg Weng [email protected]
