This fixes at least the testcase Jeff provided me with. I'm going ahead
and checking it in as obvious. I suppose we might need more of these,
on this and other ports, if they have been sloppy about zero-length
pseudo insns :-(
Would you guys please let me know whether you still see a problem, if
you get a chance to respin? I was just about to crash in bed when I saw
When I get back up, I'll build the latest binutils release on ppc64,
ppc64el and aarch64, and then bootstrap gcc with it. I should have done
that when I broadened my testing of the SFN+LVU+IEPM patchset to those
platforms, but I didn't realize I was failing to test them with an
assembler with view support, doh! Sorry about that.
