4.104.11
Last change on this file since 977c3de was 977c3de, checked in by Chris Johns <chrisj@…>, on Nov 17, 2012 at 6:34:33 AM

Refactor the ELF support to allow ELF write suppport.

The refactoring allows better reuse of the ELF support and cleans up
some hacks from the generic file and archive handling improving the
separation of the file handling from the file format, ie ELF. The
handling of ELF object files and ELF object files inside archives
is cleaner.

The refactor cleaned up the symbol handling where the symbols now
reside in the ELF file object and references are take in symbol
pointer containers and symbol table containers.

The main purpose of the refactor is to allow support for creating
and writing ELF files.

Also added an rtems-syms command where special symbol support
can be added.
