[wwwdocs] gcc-13/changes.html + projects/gomp: OpenMP GCC 13 update
Checks
Commit Message
This patch updates the OpenMP implementation status, based on libgomp.texi.
For the release notes, it also moves 'non-rectangular loop nests' up as that's
a 5.0 not a 5.1 feature.
And in line with libgomp.texi, it adds to projects/gomp/ the items for TR11,
a OpenMP 6.0 preview. (Hence, the id="omp6.0" to have a fixed id even when
the list is updated to TR12 and later OpenMP 6.0.)
Comments? Suggestions? OK?
Tobias
PS: There will be surely more updates before GCC 13 is released; I hope/assume
the next change will be for nvptx reverse offload...

The posted patch is certainly good, but doesn't do what you wrote above.
