The latest round of patches cured the original problem. Unfortunately, the
target itself is still broken. This time because of a bug originaly reported
for the e500v1 target. (27075).
I am not sure what is the right

Is there more to do? The end of the audit trail contains patches from Alan, so
it's unclear to me if the issue should remain open.

I've closed this bug incorrectly twice, the last time simply because I hadn't
committed a patch already in my tree. Edmar, please resolve this bug as fixed
if e500 is back in bootstrap land.

I am sorry, but the patches on comments 17, 18, 21, and 22 are no good without
the
patch on comment 5, which seems, it was never commited into the repository...
Can you double check this. Thanks.

Sorry! My apologies for closing this bug without checking that the original
problem had been fixed. I was focusing on the code generation problems.
