Ack, sorry. I should have sent this to llvm-commits instead. :-P Followups there please.

I intend to use this to support oprofile's ability to symbolize JITted code through the interface described at http://oprofile.sourceforge.net/doc/devel/jit-interface.html. I believe the interface will also be useful for gdb support. I'm considering adding some flags to the JITEventListener to let the JIT avoid collecting information no listener is going to use, but I won't do that

...rmation is stored in the __jitSymbolTable structure in JITEmitter.cpp, but I don't see any interface to query this symbol table. I see AddFunctionToSymbolTable() and RemoveFunctionFromSymbolTable(), but not any equivalent of GetFunctionFromSymbolTable(). Is there a supported way to get at the JitSymbolEntry for a function? If not, is there an alternate way to determine the size (in bytes) of the native function? Question (2): Does LLVM have any routines for printing the disassembly of a native code function? I see that lli can do this, but I would much prefer an LLVM library routine that I can call...
