I just read the LLVM Programmer's Manual, which mentions (but specifically does not include any details of) the InstVisitor template. Could someone please provide an example of how to use this template to find (as an example) all CallSites for the function strcpy? Thanks, Brice Lin

...nherits from ModulePass, currently iterates through the Module, Functions, and BasicBlocks multiple times (once to find strcpy, another to find strcat, and so on for various other functions). If I only care about the direct calls, would I benefit more from switching to multiple use_iterators or the InstVisitor template? - Brice On Tue, Apr 14, 2009 at 1:13 PM, Luke Dalessandro <luked at cs.rochester.edu> wrote: > > On Apr 14, 2009, at 1:49 PM, Luke Dalessandro wrote: > > I guess I should note that the "use iteration" will only work for > direct calls.

...ing to do is add a runtime check after all call instructions. To do this I would (eventually) like to add a branch to an "error" block that aborts the program. However, in trying to insert a new block after each call site, I encountered this issue. The problem I'm seeing is an InstVisitor assertion failure ("UNREACHABLE executed" and "Unknown instruction type encountered") after splitting a basic block. Here is a method to reproduce the issue: // -------------------- Test.cpp #include "llvm/IR/Module.h" #include "llvm/Pass.h&qu...

Hi, the docs for InstVisitor say that if RetType != void, one has to override visitInstruction. What is the reason for that? It's valid to define visitInstruction like that: RetTy visitInstruction(Instruction &I) { return RetTy(); } so assuming RetTy has a sensible default constructor, user won't need to over...

Branches have been created. You are free to checkin to cvs head again. I'll send mail once I have the prerelease tar balls up. Please continue to review and revise the documentation. I can fold this into the release later. Thanks, Tanya On Thu, 13 Apr 2006, Tanya Lattner wrote: > > I will be creating the release branch at 1:00pm PDT. Please refrain from > checking in from

I will be creating the release branch at 1:00pm PDT. Please refrain from checking in from 1:00-1:30pm. I will send email once I am done. Thanks, Tanya
