Re: [PATCHSET] Add error metadata to diagnostics

2023-09-07 Thread Arthur Cohen


Pushed to trunk this morning with Changelogs and SoB lines.

Thanks for the review David!

All the best,

Arthur

On 9/6/23 15:53, Arthur Cohen wrote:

This short patchset from David Malcolm enables errors to contain extra
metadata - this is particularly useful for the Rust frontend, which will
rely on that implementation to emit standard Rust error codes [1].

This series of patches is necessary for much of our more recent
additions to the frontend, including the work of one of this year's GSoC
student, Mahad Muhammad, who has spent a lot of time working on emitting
these error codes from the Rust frontend for GCC.

We will soon resume upstreaming patches from our development repository
to the main GCC repository, in the hopes of distributing the Rust frontend
as part of the GCC 14.1 release.

[PATCH 1/2] diagnostics: add error_meta
[PATCH 2/2] Experiment with adding an error code to an error

Are these OK for trunk?

Kindly,

Arthur

[PATCH 04/14] rust: Implement TARGET_RUST_CPU_INFO for i[34567]86-- and x86_64--

2023-09-07 Thread arthur . cohen

There are still quite a lot of the previously reverted i386-rust.cc
missing, so it's only a partial reimplementation.

[PATCHSET] Reintroduce targetrustm hooks

2023-09-07 Thread Arthur Cohen


Alright, was not expecting to mess up this patchset so bad so here we go:

This patchset reintroduces proper targetrustm hooks without the old
problematic mess of macros we had, which had been removed for the first
merge of gccrs upstream.

Tested on x86-64 GNU Linux, and has also been present in our development
repository for a long time - added by this pull-request from Iain [1]
which was merged in October 2022.

Ok for trunk?
