| # 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. |
