When -frename-registers got added to -O2 on mainline, there were IA-64
bootstrap failures. I had to write a patch for that. The patch can be
found here:
http://gcc.gnu.org/ml/gcc-patches/2004-04/msg01328.html
With this patch applied, the testcase compiles OK.
So it looks like we need to backport this patch onto the gcc-3.4 branch.
I am leaving for the GCC Summit tomorrow, so I won't be able to test
this until next week.
