Hi all,
I learned valgrind for several weeks and now I want to write my tool. I want to
keep the track of pointers derived from heap block, which is similar to
exp-ptrCheck. While it is hard for me to understand the IR representations of
valgrind. I checked PtrCheck's instrumentation function and there were many IR
types like Ist_NoOp, Ist_AbiHint and so on.
So I want to know the syntax and semantics of there IR representations for I
have to instrument these IRs in order to track information I want.
Where can I find detailed information about valgrind's IR representations and
can anyone show me a simple example of tracking pointer addition operations?
Many thanks.
All the best,
Nofootbird
