That helps, but as Pat reported in the bugzilla, it still is
failing.
With the following patch, we can now bootstrap on powerpc64-linux.
Is this ok for trunk?
Does this help the other architectures that are failing for the same
build error?
Ok, Dave reported in PR59009 that my last patch still left a few
build
problems on HPPA. Dave tested the patch below and confirmed this
cleans
How can there be problems on HPPA? libsanitizer/configure.tgt says
that
hppa* is UNSUPPORTED, so libsanitizer should never be built there.
Furthermore, it would be nice to understand why the sigaction is
different.
Actually, it turns out I have had a patch in my tree enabling it.
