Hi!
GCC upstream is defaulting to the V8+ baseline now for 32-bit mode on sparc64
[1].
As this change is not going to be backported according to the responsible
author [2],
I would like to ask this change to be backported in the gcc-11 package in
Debian.
I'm attaching both the patch itself as well as a Debian patch which includes
both
the patch and updates debian/rules.patch.
Could you include it for the next upload?
Thanks,
Adrian
