Hi,
Thanks for your reassurances! I should be able to get a patch ready to
make things correct again tomorrow.

That would obviously be the comprehensive way to do it, but I was
unsure how it would be viewed by others. It's a general liveness
calculation with performance implications (the X86 one you mentioned
earlier seemed to limit itself to a few instructions before giving
up).
I'd sort of thought that if LLVM has existed so long without it, that
was probably because of a policy decision rather than lack of
interest. Was I wrong there?
Tim.
