This is a small fork of gdb that is used for Rust.
Ordinarily any patch going committed here should first go upstream.
You can find upstream contribution instructions here:
https://sourceware.org/gdb/wiki/ContributionChecklist
There are a few local patches that should not be upstreamed. These
are limited to build changes needed for Rust.
To update gdb, make a new branch based on the corresponding gdb
release branch. Then cherry-pick the local changes onto the new
branch. Finally, after pushing the new branch, send a PR to the rust
project to update the gdb submodule.
