- # A bug in ld prevents us from having a (constant-value) symbol in a
- # "ORIGIN =" or "LENGTH =" expression. We fix that by generating a
- # linker file with the symbolic part of those expressions evaluated.
- # Unfortunately, there is trouble making vmlinux depend on anything we
- # generate here, so we *always* regenerate the final linker script and
- # replace the LD macro to get what we want. Thankfully(?) vmlinux is
- # always rebuilt (due to calling make recursively and not knowing if
- # anything was rebuilt).
- # The shell script to build in some kind of dependency is really not
- # necessary for reasons of speed. It's there because always
- # regenerating stuff (even for incremental linking of subsystems!) is
- # even more nauseating.
