[LLVMdev] How do clang & clang++ choose function names for LLVM IR?
...ool to do static
analysis, printing call graphs and such. When compiling C programs to IR
(and eventually to call graphs), function names remain the same (main,
function1, function2 etc.), but when compiling the same program as C++, the
function names often have cruft added to them (_Z9function1v, _Z9function2v
etc.) which doesn't make for a very pretty graph.
Why are these extra characters added when going to IR from C++, but not C?
I'm interested in what they're for and if there's anyway to avoid them for
the sake of making nice graphs.
Thanks,
David Glanzman
