I am trying to work through the usage of thinlto for distributed builds.

This makes it less likely that re-use will cause invalid analysis results. BUT it makes it more likely that when we access a dangling pointer, it falls into a poisoned heap area. So the net result is that it catches dangling pointers better. Or to put it another way, the &q...

...e.g. SimplifyCFG) 3. BOOM Notice that this ends up happening even though SimplifyCFG ultimately invalidates LVI. But that only happens after the AssertingVH has been triggered. We would avoid this issue in principle by just switching those AssertingVH to observing pointers, but then we would have dangling pointers. I'm pretty sure that any analysis that keeps pointers to IR is in fact ending up with dangling pointers like this. I've noticed that AssumptionCache using CallbackVH that allow it to update its data structures correctly in this case. Just using regular pointers will end up wi...

Hi, dbcheck tells us we have two "dangling forward links" that I am trying to get rid of. On my test domain, I have simply done ldbedit -e nano -H ./CN=CONFIGURATION,DC=SAMBA,DC=COMPANY,DC=COM to remove them. While that seems to have worked nicely, dbcheck report zero errors now, it is something that I should never have done, o...

...ar student in Computer Science at Pusan National University. This summer I would like to contribute to your project, however I do not have experience in contributing to open source societies so far. Therefore, I would like to start with not a difficult, in my opinion, project as "a checker for dangling string pointers in C++". I am currently writing proposal and would like to know whether there is an additional information about the project I need to know and how I can get started on the project. Thank you.
