[wwwdocs] Document existence of openacc-gcc-9-branch

[wwwdocs] Document existence of openacc-gcc-9-branch

[Julian Brown]

[-- Attachment #1: Type: text/plain, Size: 577 bytes --]

Hi,

I've pushed a new branch "openacc-gcc-9-branch" to the Git
mirror (i.e. as a Git-only branch), for development of OpenACC and
related functionality on top of the GCC 9 branch. It's currently based
off the gcc-9_1_0-release tag, and contains a number of patches mainly
merged from either the openacc-gcc-8-branch, or from further-developed
versions of those patches that have been submitted for upstream review.

This patch updates the svn.html page to point to the new branch rather
than the old openacc-gcc-8-branch, which is retired now.

OK to commit?

Thanks,

Julian

As obvious, but please also add an "openacc-gcc-8-branch" stanza next to
"openacc-gcc-7-branch" in the "Merged Development Branches" section, and
update the "gomp-4_0-branch" and "openacc-gcc-7-branch" stanzas
accordingly.

Well, actually please move "gomp-4_0-branch", "openacc-gcc-7-branch", and
"openacc-gcc-8-branch" into the "Inactive Development Branches" section,
for all "These branches are inactive and contain work that might not been
merged": they all contain some changes that have not been forward-ported
to their later instances.

Actually, the branch is currently based on the point at which 
gcc-9-branch branched off trunk (git commit 
6977c7629669452bbf954a2800014a89c835cf87), rather than the 9.1.0 release 
tag. To fix this, I have now merged in the changes from between that 
point and the gcc-9_1_0-release tag, minus the erroneous change to 
BASE-VER on the last commit.

(Later also for OpenMP support, in particular for AMD GCN offloading;
hence the decision to tag this "omp" instead of just "openacc" going
forward.)

> on top of the GCC 9 branch.

Based on the releases/gcc-9 branch point, I've now rebased/recreated this
for the new Git world, with only minor changes:

  - for easy cross-referencing, in the commit logs point to the original
    Git-mirror og9 commits: "(cherry picked from openacc-gcc-9-branch
    commit [...])"
  - use 'ChangeLog.omp' files
  - merge the "Add missing ChangeLog.openacc entry" commit into what it's
    fixing up -- to avoid having to edit the commit log for the changed
    'ChangeLog.omp' filename ;-)
  - fix a handful of "git-svn" commit author IDs, which the server-side
    Git hooks probably would've rejected to be pushed

Given that nobody protested to my suggestion in
<http://mid.mail-archive.com/87zhd68tot.fsf@euler.schwinge.homeip.net>
"Git branch name to use for development branch based on release branch,
not master", I've pushed this as devel/omp/gcc-9, and pushed to
gcc-wwwdocs the attached commit 6b92a4c7033db33ed5b6827e826a561077ed2181
"Document devel/omp/gcc-9 branch".

[OG9][devel/omp/gcc-9] Merge from gcc-9-branch [was: devel/omp/gcc-9 branch]

[Tobias Burnus]

I have now merged the GCC 9 changes into the branch;
before it was up to date with 'releases/gcc-9.1.0',
and now it is with today's
r9-8340-g7beafc829c5b122298093ba517023015611aeca8

This was done in two pieces (9.1.0 to 9.2.0 changes,
and then to today's as only 1000 commits are permitted.)

The main reason for doing this merge is GCC 9's
commit r9-8063-g75003cdd23c310ec385344e8040d490e8dd6d2be
of Fri Dec 20 17:58:35 2019 +0100:
"backport: re PR sanitizer/92154 (new glibc breaks arm bootstrap due to libsanitizer)"

Despite the PR title, that commit also fixes bootstrap on x86-64-gnu-linux.

Cheers,

Tobias
