Yes, I wish to solve this problem, I tried, and it was basically the
way Debian and AIX used [1]. But David Holmes wishes a POSIX version,
that patch failed to be pushed. I think I will go on to work on it,
however I do not have Solaris and macOS for test, I am working on
preparing these OSs.

What is https://git.launchpad.net/~openjdk/ubuntu/+source/openjdk/+git/openjdk/tree/debian/patches/hotspot-mips-align.diff
for? We build mips zero without this patch.

Cheers,
