[LLVMdev] [ LLI / MCJIT] re-initializing of lli ...

[Lang Hames]

Hi Armin,

Argument parsing isn't handled by the JIT. This sounds like you're making
redundant calls to cl::ParseCommandLineOptions ?

Deleting the ExecutionEngine and any RTDyldMemoryManager instances that
you've created should be enough to reset the JIT.

Cheers,
Lang.
