Hi, This patchset contains the initial changes to add the libgrust folder to gcc, which will later contain libraries used by our Rust frontend.
This work was done by Pierre-Emmanuel Patry as part of his work on supporting procedural macros in our frontend. It was then tested by Thomas Schwinge, and finally pushed by Marc Poulhiès. Kindly, Arthur [PATCH 1/4] libgrust: Add ChangeLog file [PATCH 2/4] libgrust: Add entry for maintainers [PATCH 3/4] libgrust: Add libproc_macro and build system [PATCH 4/4] build: Add libgrust as compilation modules
