Hi, I am a student at IIT Kanpur. I am working on Path
Profiling, i just came with a need to know about the number of
static paths in a program(actually in a function) before it's
actually get run. As i saw in PathProfiling.c file in
llvm\runtime\libprofile they are just storing the path
information at run time and dynamically adding entries for the
new path. But i need to know the number of static paths (total
paths in a function ) whether they are executed or not. Please
help me know that, can LLVM provide me with number of static
paths or not.<br clear="all">

I don't think LLVM has an analysis pass to do this. However,
writing a new LLVM analysis pass to count the number of paths should
be pretty straightforward.<br>
<br>
If you decide to write such an analysis, I recommending reading the
relevant portions of:<br>
