Hello, I'm trying to generate unique identifiers for some trees at link time. I understand that there are already some unique identifiers in declarations (DECL_UID) and perhaps others. Do all trees have unique identifiers or only declarations?
Alternatively, if they don't have unique identifiers, again, I am trying to generate my own at link time. I originally was thinking about just having a counter and incrementing it every time I add a tree of interest to this data structure that I use to keep track of trees. However, with the parallel LTO framework, this would mean that identifiers will be duplicated across different partitions. Has anyone done something similar where information across partitions needs to be communicated? What I was thinking of as an alternative to communicating this information across partitions is to record the process id then use this information to generate a unique identifier based on the counter and the process id that is processing the partition. This derived identifier would be generated during WPA time. Has anyone had any experience doing something similar? I would be interested in seeing similar examples and use cases. Thanks!
