257 Byte swapping is a big issue in cross linking, as the system running
264 system byte orders are the same, and no byte swapping
274 The big exception to libelf transparently handling byte swapping is
277 cannot do byte swapping for them. If your code examines or modifies
278 such data, you are responsible for handling the byte swapping required.
286 that the vast majority of byte swapping you have to handle
289 libld contains generic functions for byte swapping:
