Hi, I am still working on understanding the LTO framework and how the gimple representation works across multiple partitions. I found myself printing all global variables and printing their DECL_UID. I noticed that for some variables, their DECL_UIDs were different across different partitions. That is, a single global variable has different DECL_UIDs in different partitions. Is this the correct behaviour? My understanding of DECL_UID is that for every declaration there is a unique identifier, but is this not the case during LTO?
I am building a transformation on top of releases/gcc-11, maybe newer commits address this, but I haven't seen a discussion in this mailing list. Perhaps in patches, but I don't follow that mailing list too closely. Thanks, any help is appreciated!
