Hi,
In linux-next as of today (0824), all h8300 builds fail for me with an
internal
compiler error.
Building h8300:allnoconfig ... failed

I tried both gcc 5.1 and 5.2, built with the patch set available to me.
Is there a more recent compiler / patch set available that might fix
the problem ?
No.
I tried gcc 6.0. It got same error.
It looks optimization problem on h8300 target.
I will investigate it.
I get the same ICE with c6x gcc 5.1
Interesting. h8300 was the only gcc 5+ compiler I had used so far.
Just for fun, I built an alpha toolchain with gcc 5.1. Same problem there.
So it looks like it isn't a h8300 problem after all, it is a gcc problem.
Updated subject line, and copied rcu maintainers.
