Here are the test results for tree-ssa with your patches applied.

I've compared these results with
http://gcc.gnu.org/ml/gcc-testresults/2003-08/msg00459.html:
The g++/objc test summaries are identical, so no c++ regressions.

For gcc, there are 19 new failures, 4 fewer expected failures and 4 new
unresolved test cases:

loop-2e.c is a GIV test, so that one can be blamed on the cripled loop
optimizer.  The Wunreachable-1.c and 920507-1.c failures are due to
wrong line numbers.  I don't know what happens with the cmdline tests,
it says ``cc1: error: missing argument to "-M"''.  The other 2 ate
indications that something broke more seriously.

Overall not that much breakage, nice!

Steven
