Hi Michael,<div class="im"><br>

I am in the process of writing a paper that will target some AI conference,<br>
and I would like to ask if there are any relevant publications of yours or<br>
in general that showcase the possible advantages of trace-based JIT<br>
compilation over method-based JIT compilation or static compilation.<br>

this publication has a nice listing of benefits over static compilation:<br>

Some of it is outdated, as I find in particular that compiled traces are<br>
very nice on contemporary speculative, out-of-order executing, branch<br>
predicting, hyper-threading CPUs in ways that made no difference on deep<br>
pipeline CPUs of old. It's a great read nonetheless.<br>
<br>
Method-based JIT compilation does not play as well with modern CPUs, as<br>
the greatest benefits are had from the inlining of functions and removal<br>
of branches.<br>
<br>
Even for C++, vtable indirection and the trampolines for calls across<br>
shared libraries are tough on modern CPUs. Inlining and finalizing calls<br>
helps, but with static profiling you only have one choice of organizing<br>
the code, on one "representative" data set.<br>
<br>
