Thanks for spotting the typo. I also updated the patch to ensure that
we are giving an address register indirect to clr.

Jonathan,
The testcase seems to work with GCC 4.1.
As far as getting the testcase into the testsuite, you need to post a patch
first.
The best thing to do at this point is to reduce the testcase so

By the way, unpatched cc1 propagated 95619 constants while compiling cc1-i

Patched one propagated 96482 constants in the ccp run (that is, not store-ccp).

because ccp_initialize thinks that a PHI node is varying if at least
one of PHI argument is varying.
