Sorry for the delay. I posted the fix at
http://gcc.gnu.org/ml/gcc-patches/2008-08/msg00112.html.
I would appreciate if someone could test the cumulative patch of three fixes
for ia64 speculation support or provide a single-file executable testcase for
this bug. Here are links to two other bugfixes for ia64 speculation support:
