So this is, after all, an assembler bug and not a GCC bug?

I wonder if we should attack this from a different angle. We have been trying
to make the .pred.mutex.rel info more accurate to avoid this warning. If we
can't do that I wonder if we should make GCC more conservative

initial patch
This patch fixes gcc.c-torture/compile/920625-1.c, but unfortunately doesn't

gcc-c.torture/compiler/920625-1.c would also be failing for the same reason,
except it has dg-prune-output hacks to discard the assembler warnings. We
should fix the IA-64 compiler, and then eliminate these

Any ideas on how to fix the compiler? The best idea I could come up with was
to check each basic block to see if there are any conditional sets of predicate
registers in it and add pred.rel.mutex lines for those
