[LLVMdev] generating a dynamic callgraph with llvm-prof

[John Criswell]

Dear Eric,

Swarup and I wrote a dynamic slicing system called Giri several years 
ago that recorded the execution of every call instruction. It's not in 
the LLVM tree, and I don't think it works with the latest version of 
LLVM, but it'll give you what you want.

Swarup, is that code publicly available somewhere?

Regards,

John Criswell
