The log got a bit off topic because there were two separate breaks
of the Ada bootstrap.  The first was fixed several days latter by
Richard Kenner's patch to trans.c.  I spent quite a bit of time
trying to track down the cause of the first break only to find that
Richard had already fixed it ;(

As for a testcase, I don't have one.  My knowledge of Ada is limited.

As for testing on hppa, arrangements can be made.  I believe an
account was setup for you on gsyprf11.external.hp.com a few months
ago.

For the reasons listed in your patch submission, it would be nice if
this could get fixed.  However, I'm away for 8 days next week and my
time is very limited for awhile.  PR 13324 appears similar and involved
the movstrsi/clrstrsi patterns.
