...ifferent but similar purpose, which effectively implements a stronger virtual machine on top of the LLVM IR. I have been very happy with the decision to use LLVM instead of, say, working with x86 directly. On the other hand, if you are only interested in a teaching tool, why not use something like SPIM for example? If your usage model is different than SPIM then explaining it may clarify how LLVM would fit. http://pages.cs.wisc.edu/~larus/spim.html - Daniel > Thanks, > M.

Daniel,   Thanks for the reference to SPIM. It looks interesting, but appears to be an assembler that can also execute the code (it does not execute binary files). In addition, I'm probably asking for too much. Ideally, I'm looking for something like MS Visual Studio with that executes on a virtual software machine, whose source cod...

Is there a similar open-source or free simulator for ARM that would run llc- or lli-generated code on Linux? Would QEMU work, perhaps? Caveat: I haven't used it personally for this sort of thing. Static code-gen (via llc) may change, but it's production qu...

Hi Daniel,   Thanks for your help.   You mentioned that "the current interpreter makes no pretense of running on a "virtual machine"", but isn't the interpreter itself a virtual machine? I'm not looking to emulate any particular processor - just interested in a tool that will help teach how a processor works.   Can LLVM help, or am I completely off track?   Thanks, M.

LLVM is a lot of things, the web page gives some important areas (http://llvm.org/).
