Re: Bootstrap failures on ia64 (was Re: Readiness of tree-ssa)

gcc-3.3 does have _Unwind_Resume_or_Rethrow. I don't see how this can work when 3.3 is the bootstrap compiler. My IA-64 build machine runs debian testing which uses gcc-3.3 as the system compiler, so I believe I have already tested this and shown that it can't work, though it is possible that I made a mistake somewhere.

I.e. it's always better.

I think that is arguable. It is harder to write the documention if you have a configure test and will sometimes work and sometimes fail to work, as opposed to one that always fails.
