Hello R experts, I plan to develop a tool for dynamic analysis of R programs. I would like to trace function calls at runtime, capturing argument and return values. Following a suggestion made some time ago on this list, my high-level implementation strategy is to rewrite the AST, augmenting call expressions with pre-call and post-call shims to capture the arguments and return value,

...genthat We don?t really deal with NSE though. It could be something worth thinking about for us. The contact for genthtat is Filip. We are also writing a tool for analyzing promises and generating execution traces within the R VM. This is available in https://github.com/PRL-PRG/R-dyntrace Aviral and Konrad are the contacts there.

...pass builds? Similarly, would work in the direction of supporting those builds be welcome? If so, it's something I'd like to look at.

Thanks Dan and Jon. I made an incorrect assumption that the "use" iterator was actually giving me the "user" when de-referencing it. Did it always have this behavior in previous LLVM versions? I've seen lots of examples of the "use" iterator being dereferenced and resulting Instruction pointer being treated as the "user"? Thanks, Zack On Tue, Jun 9,
