Could we just do a regular merge? It looks like it'd go through with no conflicts

Could we just do a regular merge? It looks like it'd go through with no conflicts

Sounds like we've already discussed all this when we decided how to proceed. At least here is public and other interested parties could chime in (e.g. @thesamesam ).

I would like to use the process as discussed, at least for a few rounds. We can always adjust if something is painful, not friendly, anything else.

The good property of doing this is that the main branch is always mostly ready for the upstreaming. The main branch is always: a few gccrs commits, an empty merge commit with the --strategy=ours which first parent is a sequence of gccrs commits rebased over an upstream gcc base (recent). The git history becomes a bit like the history of the gccrs commit rebased: first parent of the merge is the current series, the second parent is the previous branch (from there, you again have the exact same pattern).

The daily routine is rather easy and doesn't involve to be a git expert to do. See for example my WIP for gerris...

https://github.com/Rust-GCC/gerris/blob/dkm/upstream-command/src/rebaseupstream.rs => this is used to rebase the github branch onto a fresh upstream (it rebases onto a new base, and it moves all the commits that were after the commit before the new one, so that you have: merge<-gccrs sequence<-fresh upstream gcc).

https://github.com/Rust-GCC/gerris/blob/11b5ee7372da00a40a493a88a53a3530cd81d38b/src/upstream.rs#L249 => this is used to prepare the branch before upstreaming. It is not 100% done, but it gives a good start.

I fear that having regular merge would make things harder to read, and the upstreaming would need a different process. Again, I'm not saying it's not a good idea, but I think I like the process as proposed initially and would like to give it a try.

Alright, we can table the discussion for now. I figured I'd bring it up again since #3761 has already been merged.

Alright, we can table the discussion for now. I figured I'd bring it up again since #3761 has already been merged.

The goal, at least as I understand it, is to do similar merge on a weekly basis, with corresponding upstreaming...

diagnostics: remove "json" output format
51ce373 
The "json" output format for diagnostics was deprecated in GCC 15, with
advice to users seeking machine-readable diagnostics from GCC to use
SARIF instead.

This patch eliminates it from GCC 16, simplifying the diagnostics
subsystem somewhat.

Note that the Ada frontend seems to have its own implementation of this
in errout.adb (Output_JSON_Message), and documented in
gnat_ugn.texi.  This patch does not touch Ada.

gcc/ChangeLog:
	* Makefile.in (OBJS-libcommon): Drop diagnostic-format-json.o.
	* common.opt (fdiagnostics-format=): Drop
	"json|json-stderr|json-file".
	(diagnostics_output_format): Drop values "json", "json-stderr",
	and "json-file".
	* diagnostic-format-json.cc: Delete file.
	* diagnostic-format.h
	(diagnostic_output_format_init_json_stderr): Delete.
	(diagnostic_output_format_init_json_file): Delete.
	* diagnostic.cc (diagnostic_output_format_init): Delete cases for

	* diagnostic.h (DIAGNOSTICS_OUTPUT_FORMAT_JSON_STDERR): Delete.
	(DIAGNOSTICS_OUTPUT_FORMAT_JSON_FILE): Delete.
	* doc/invoke.texi: Remove references to json output format.
	* doc/ux.texi: Likewise.
	* selftest-run-tests.cc (selftest::run_tests): Drop call to
	deleted selftest::diagnostic_format_json_cc_tests.
	* selftest.h (selftest::diagnostic_format_json_cc_tests): Delete.

Adjust external crate lowering and type checking
f5dd7c5 
The 2.0 name resolver is provided through
ImmutableNameResolutionContext after it is done being mutated. The
typechecker attempts to use ImmutableNameResolutionContext, so it needs
to be run after ImmutableNameResolutionContext has been initialized
(after all name resolution has been completed). Additionally, although I
haven't seen any issues with lowering AST to HIR before name resolution
2.0 is complete, it makes sense to perform all lowering in lockstep as
well.
