llvm dev - Jan 2005 - [LLVMdev] getting all def-uses

Hi,

	I want to get all the d-u pairs exercised at run-time. I am doing
two things for this. I am useing the d-u iterator to instrument all uses.
I also want to get an address trace. What are the instructions I should
insttrument. Is load and store sufficient. Also, how do I go abt doing
this ?

Thanks
-Sriraman.

Hi Sriraman,

If you are looking for accessed memory locations, instrumenting loads and 
stores should be sufficient.  To do this, just walk to program (e.g. all 
BB's in a function, all instructions in a BB) and for each load and store 
instruction insert trace code.

Let me know if this doesn't make sense or if I misunderstood the issue,

Thanks Chris. Yes that was what I was looking for.
