I have added a new optimization to gplink. Dead sections are removed
when the optimization level is 2 or higher. A dead section is any
section that doesn't have relocations pointing to its symbols. This
means the code or data in the section is never accessed. This
optimization removes the section and its symbols to reduce program and
data memory. This optimization will not remove any absolute sections.
Preliminary tests are working well. The code is in cvs. I need to
decide if more exceptions should be allowed. For example, don't remove
sections in protected memory. I am open to any suggestions.
