Does anyone have any ideas about when X86_SE parser stopped working? The
last time it passed for sure was the end of February, but on March 16th
Ali updated the stats and so it was presumably working then too. I'm
running at that changeset right now to confirm that. There weren't any
X86 specific changes recently, but there were a few O3 ones which might
have changed the stats. The output is below, and you can see the biggest
change percentage wise was icache writebacks. Most of the changes are
related to memory somehow. After the stats is info about a change that
may have caused the problem.

description:
O3: Fix unaligned stores when cache blocked
Without this change the a store can be issued to the cache multiple
times.
If this case occurs when the l1 cache is out of mshrs (and thus blocked)
the processor will never make forward progress because each cycle it
will
send a single request using the recently freed mshr and not completing
the
multipart store. This will continue forever.
