I suppose that you want this to ensure that errors reported by Valgrind are referencing the JITed function name. To my knowledge, there is nothing. I remember seeing a note somewhere telling it would be nice to support better info for JITed code. As part of the integration of gdbserver in 3.7.0, I somewhat looked at what is currently going on this aspect in gdb: in gdb (7.4, under developmnet), an API is being defined to let the JIT compiler provide (easily) a subset of the debug information sufficient to let gdb to stack trace and similar. (search on the web for "jit-reader.h" for details). If more advanced debugging is needed, the JIT compiler is supposed to generate dwarf info for gdb. I guess that one way to have better support for JITted code in Valgrind would be to intercept/hook on the same API.
