heavylifting (like loop restructuring optimizations) after

I think you're missing the point here. The whole idea of LLVM IR is that it doesn't have various "...

This should work fine, but then why support intrinsics in LLVM at all.
I understand you're talking about an initial implementation.

DTrace in Perl: What probes should we have?
As of patch 32953 dtrace support is in bleadperl (5.11.0). The probes
are based on Alan Burlinson''s original blog post on the subject:
http://blogs.sun.com/alanbur/date/20050909
By guarding the probes with PERL_SUB_*_ENABLED the performance hit is
unmeasurable.
All the necessary bits already existed in the wild. I just assembled
them and made the necessary changes to
