You'll have to figure out how to find the plt stub though. It's not marked in any way. The only thing you get a pointer to is the .IA_64.pltoff entry. For userland, the .plt stub has to use an indirect branch because the first invocation goes through the dynamic linker. Then we update the .pltoff entry and so subsequent calls go direct to the target. r~
