I'm trying to find evidence of non-PLT ifuncs, but have been unsuccessful so far. >From ifunc.txt at https://sites.google.com/site/x32abi/documents: | All references to a STT_GNU_IFUNC symbol, including function call and | function pointer, will go through a PLT slot, which jumps to the address | stored in the GOT entry. If the STT_GNU_IFUNC symbol is locally defined, | a R_*_IRELATIVE relocation will be applied to the GOT entry at load time. | Otherwise, dynamic linker will lookup the symbol at the first call to the | function and update the GOT entry.
