This is correct so far.

I was asked to move to compile only, because a run test takes a lot of time.
I was told that the run test compiles the code multiple times with different
optimization. This issue was deemed to be solely on the compile stage and was
not influenced by optimization. Therefore I agreed to switch to dg-do compile.
That the test is fine for running, too, is merely for my training of how to do
that. My opinion is, that dg-do compile is sufficient to prove, that PR60414 is
resolved, because that is the sole purpose of the patch. I understand
Dominique wanting to have the dg-do run, because the effectiveness of the patch
is only shown on running the test. Is there a compromise of running a test, but
only for one optimization stage? Then may be we can do that.
