- /*
- * This function is _not_ called directly. It is jumped to from PLT when
- * attempting to use a symbol that has not yet been resolved. The first
- * time a jump symbol (such as a function call inside a shared library)
- * is used (before it gets resolved) it will jump here. When we get called
- * the stack contains reloc_offset and tpnt is in MOF.
- *
- * We save all the registers, setup R10 and R11 with the right arguments
- * then call _dl_linux_resolver(tpnt, reloc_offset). _dl_linux_resolver()
- * figures out where the jump symbol is _really_ supposed to have jumped to
- * and returns that to us. Once we have that, we overwrite tpnt with this
- * fixed up address. We then clean up after ourselves, put all the registers
- * back how we found them, then we jump to where the fixed up address, which
- * is where the jump symbol that got us here really wanted to jump to in the
- * first place.
