and shortly its mirrors.  It has been generated from SVN revision 236809.

I have sofar bootstrapped the release candidate on x86_64-suse-linux-gnu.

Please test the release candidate and report any issues to bugzilla.

If all goes well I'd like to release GCC 5.4 at the beginning of next

Bootstrap and test on arm-none-linux-gnueabihf looks fine.
Unfortunately, on aarch64-none-linux-gnu I noticed a regression compared to
GCC 5.3:
FAIL: scan-assembler-times bif\\tv 1

This is PR 68696 that has been triggered on that branch.
The patch fixing that is at:

I have bootstrapped and tested it on aarch64-none-linux-gnu on top of the 5.4
and it fixes the regression. It applies cleanly to that branch.

Is it okay to backport it to the branch?
While it doesn't look like having the same cause (r231178) the patch
looks safe to me to backport.

Indeed, the bug is a missing pattern in the backend that ends up
with us relying on xor+and sequences being emitted in a certain order
after the tree passes, so it can be triggered by any of a number of tree-level

Thus, ok.

I'll commit it shortly.
