However, I should note that although libvtv builds and installs for Power, it
fails the testsuite completely, so we are going to leave this disabled for now.
 I'll open a bug report on the test failures.

Thanks, Ramana!  I've verified that this is working ok for Power as well.

The ICEs are fixed on arm and aarch64 when turning on vtv. I haven't done the
work to verify this on powerpc but I expect the problem to be fixed there too
as the bug really was in varasm.c

(In reply to Richard Biener from comment #3)
> What GCC version (with VTV enabled) did work for you?

I do not think any version of GCC with VTV enabled has worked for AArch64 or
ARM - I failed to notice the special casing for .vtable_map_vars in
assemble_variable when I filed the bug.
