[llvm-dev] How to add custom instrumentation?

[Alex Denisov via llvm-dev]

Hi everyone,

I run some functions using ORC JIT, now I need to add custom instrumentation.
I want to add two callbacks to each function: ‘enterFunction' at the beginning and ‘leaveFunction' at the end.
Intuition says that I could ‘just' insert CallInst's to the first and the last basic blocks in the function.

Am I correct? Are there any other/better way to do this? Is there anything special I need to be aware of?

Thank you.
