llvm dev - May 2014 - [LLVMdev] Identify which LLVM function is currently being invoked ?

Hi All
         Is there any way to identify which LLVM function is currently 
executing in the program. It would be nice to know or print what is the 
corresponding LLVM function is executing/


Thanks

Regards
Sri.

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)
