Sigh.... thank you :)

I'll blame this on the construction work going on in the building /s



Thanks Thomas :)

Hi Arthur!

This patchset contains around 80 commits concerning the Rust frontend.

Did you not intend to actually 'git push' those?  ;-P

We have been hard at work trying to get the Rust core library to
compile, and hope to push more commits in the coming days as we try
and upstream a more recent version of gccrs. All of the team has done
a tremendous amount of work in the last few weeks, as we get closer
and closer to compiling libcore 1.49.

Our focus before GCC 13 releases is to improve the documentation of the
compiler and write more about the various flags used by the frontend,
which a user will need to understand and interact with.

The commits we will be pushing before GCC 13 releases will not contain
any "major breakthrough", as some functionality required to compile
libcore properly will still take some time to implement. Very often used
Rust macros such as `format_args` are defined within the core library,
and require a high amount of work on the compiler side.

Furthermore, integrating libcore as part of GCC will require
significant build system changes which are incompatible with the current
GCC stage. We will be making these changes as soon as possible and
integrate a version of libcore in GCC 14, as well as an implementation
of the libproc_macro crate. We will be submitting these patches and
pinging build system experts for extensive reviewing.

Thank you to everyone involved with the project, and to everyone who
has helped us.

All the best,

Arthur
