I haven't, but it wouldn't be too much effort do this.
I'll try stage 1 tonight - i.e.,

Worked around by compiling this file without -ftree-loop-linear
Could you verify that the attached patch fixes also this probl

Sebastian,
Here are (attached) results for testing HIRLAM with and without
-ftree-loop-linear.
As you can see, the results are neutral: 4 loops fewer vectorized, but
about 50 fewer recognized.
Now I like to redo that test with -ftree-loop-distribution. Can you
send me a patch against the
