The difference is: R_PLT_PC is considered a PLT-generating relocation but R_PC isn't. If the target symbol is non-preemptable, an R_PLT_PC gets optimized to an R_PC, and the R_PC is considered a link-time constant. mountain bike marathonWebb13 apr. 2024 · She told her followers: “For the people commenting about the photo apparently being edited you can quite clearly see that it’s my hair and not the tiles."
