...the .dynamic section of an application where possible. In particular we would like to have this option for Fuchsia. Other dynamic linkers, like musl, already have some support for this on non-MIPS targets as seen here: http://git.musl-libc.org/cgit/musl/tree/ldso/dynlink.c#n1629. In particular the DT_DEBUG_INDIRECT entry is recognized. This change would refactor code that already exists for MIPS specific .dynamic sections and make them available to other targets. Mostly this would just require renaming some things and moving a few lines around. The biggest part of this change would be to add the flag. I prop...

...The only reason for .dynamic to be > writable is DT_DEBUG which is something we never intend to support.

It might be easier to have an option for making .dynamic be read only and the logic for emitting DT_DEBUG becomes ".dynamic is rw or mips". BTW, dynamic linkers really never relocate the .d_ptr entries? What are you guys usin...
