[LLVMdev] Identify which LLVM function is currently being invoked ?

[Philip Reames]

There's no general way to do this, but if you control the IR, it's 
pretty easy to insert a call to a trace function at the beginning and 
end of each function.  You could also write a pass to do the same thing.

basic steps:
- add a function declaration to the module for your trace function (i.e. 
"puts")
- insert calls to that function using constant strings as arguments (so 
the address is fixed)
- provide a definition for your trace function (i.e. linking)
