[LLVMdev] Exception Handling Proposal, Second round Re: LLVMdev Digest, Vol 83, Issue 30

[Peter Lawrence]

Renato,
                I agree with what Andrew said, but would have worded  
it differently. All optimizers (that
I am aware of) require explicit control flow, so things like  
exception-throwing-divide-instructions
need to be converted into IR that are Block-Terminators.  Andrew was  
explaining how this is
a non-performance issue in practice, I am explaining how this is a  
requirement of how optimizer
are implemented in practice.

-Peter Lawrence.
