Hi Duncan, Why to break? I wish to analyse all the operands of getelemetptr instructions. For which I iterate over the code and get the instruction of interest by getopcode == getelementptr. But the getelementptrs in this form as in my last mail are getting away from my pass. So i wish to break it. I have a work around if breaking is not possible, but I think it may be a c...

...bounds (which were relatively few in real programs). That's something I'll have to fix when I reintroduce BreakConstantGEPs into mainline SAFECode. :) -- John T.

Dear All, I wish to iterate over all instructions (where opCode == desired_opCode). I could iterate over all the instruction expect the nested instructions like: %add.ptr229 = getelementptr inbounds i8* getelementptr inbounds ([4096 x i8]* @_Func1, i32 0, i32 0), i64 %idx.ext228 I wish to break this nested instruction in two instructions. Please let me know if there is already existing method
