...ation time)?
I wanted the comparison to check whether the issue is just "codegen is
slow", or more specifically that JIT codegen is slow. You seem to be
under the impression that it will be significantly slower, but I don't
think it's self-evident. (The output of "time llc dumpedmodule.bc"
would be sufficient.)

Sorry Eli. I misread your message as if you were suggesting to measure
the time required for dumping the module as LLVM assembler.
llc needs 45 seconds. This is far worse than the 33 seconds used by the
JIT. Maybe llc is using optimizations. My JIT have no opt...
