Number of load instruction in a program

Question

How to count total number of load instruction on a simple "hello world" program through LLVM ??

Do you want to count the number of load instructions that appear in the code, or the number of load instructions that will be performed when the code is ran? — Oak, Mar 19 '13 at 20:12

Write a pass which iterates over all the instructions in the module, then count the number of instructions that fulfil isa<LoadInst>(I).

See the programmer's manual for how to iterate over all the instructions.

If you're not sure how to write a pass, take a look at this handy guide.
