I can reproduce it but I have other changes in my toolchain which could be
exposing it.

Note my testcase is with -mabi=ilp32 too.

And the reduced testcase needs -mcpu=thunderx too.  I am trying to see if this
fails on the trunk or only with my code changes.

I can't get a testcase that fails with the non-modified trunk.

My problem was just introduced.

The original problem should have been resolved with:
https://gcc.gnu.org/ml/gcc-patches/2013-12/msg00151.html

so still waiting.

I can't reproduce this with current trunk either.
Tejas, do you think this can be closed?

I remember the ICE was quite sensitive to any small change to the test case. If
you can't reproduce this, fair enough, it might have been fixed or gone latent.
I hope it's been fixed. :-)

 Reduced test case for LRA ICE.

Sorry, I can not reproduce it on the today trunk (I tried -O[0-3] including
-O2).
