.elf weak symbol definitions

[gtackett]

For some work I'm doing that involves linking together modules in one of Microchip's xc16 C RTLs, it would be really handy if, when an elf module is loaded, the weak attribute of defined symbols could be carried over into some attribute of the imported symbols that Ghidra creates.

That would allow my module linking code to distinguish and choose between weak and non-weak definitions.

I don't believe there is already an API method named something like genericSymbol.isWeak(), or that a generic symbol has a "weak" attribute that can be tested, already exists?

If this would be practical to implement I can submit an issue for it.

I have submitted enhancement request 2720 suggesting that Ghidra should support a "weak" indicator for imported symbols. Anyone who's interested in the subject is still welcome to chime in here.
