If SVM has the same behavior as VMX, the MONITOR will be disarmed on VM-Enter, i.e. the VMM can't do anything useful for MONITOR/MWAIT.

...look at the emscripten project ( https://github.com/kripken/emscripten/wiki ) , which is a Javascript backend for LLVM. It's actively maintained and might give you some better ideas of how to do something like this once you can get back to bitcode level from assembly. Also take a look at Disarm ( http://code.google.com/p/disarm/ ) which is an ARM machine code to LLVM-IR disassembler. There may be quite a bit of relevant work done there.

Not sure if it is disarmed on VMRUN, but the MONITOR/MWAIT instructions are part of the GHCB spec, so they are implemented...
