Hi Everyone @ the Yocto project,
I'm Shane Peelar, a PhD Candidate at the University of Windsor.
I'm writing to you about prelink-cross, as part of the Yocto project.
Specifically, I'm looking at using it with executables built using
`-fno-plt` under GCC.
I wasn't quite sur
Any of them on the system pretty much, and yes they are also built with
-fno-plt.

for the section named ".plt" in the ELF.
4. Assert that the section was found
5. Write the address of .plt + constant (dependent on arch) to got[1]
I tested out making the assert conditional and nothing seemed to break at
least.

Great! Would you be willing to accept a patch that makes arch-x86_64.c
handle that condition like the other arches?

Make an assert in arch-x86_64.c a conditional if to handle things the same
way as other arches.
Enables binaries built with -fno-plt to be prelinked.
