Test failures when running make -k check on master branch

Test failures when running make -k check on master branch

[Zhao Wei Liew]

Hi,

I'm trying to run the test suite on the master branch. These are the
commands I ran by following https://gcc.gnu.org/contribute.html:

$ make bootstrap
$ make -k check -j22

I added -j22 to utilise all my CPU cores.

However, I'm encountering some test failures even when I didn't change
anything in the code. Is this expected/normal?

Here are some of the test failures:

Context: I'm a new contributor, looking to contribute an optimization to
fix this bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95424. In order
to test the patch, I'm trying to run the testsuite before and after the
patch, during which I encountered these failures.

You can compare your results with recent ones from other people using the
same target:

https://gcc.gnu.org/pipermail/gcc-testresults/2022-January/date.html

I don't know anything about the current state of the Fortran tests. If you
are the only person seeing those failures it might be worth asking on the
Fortran mailing list. I don't think many of the fortran devs read this list.

I see, thanks a lot!
