Rui Ueyama 7971152589 ELF2: Do not set default values that will always be overwritten. 
These member variables are overwritten unconditionally by Driver,
so setting default values would be confusing.

Davide Italiano 6d328d3841 [ELF2] Initial support for local symbols. 
Symbol table is now populated correctly, but some fields are missing,
they'll be added in the future. This patch also adds --discard-all
flag, which was the default behavior until now.

Rafael Espindola 4340aad144 Start adding support for creating shared libraries. 
They are not fully functional yet, but this implements enough support for lld
itself to read them.

With that, delete the .so binary we were using for tests and start eating our
own dog food.

Michael J. Spencer 8a4145411f Initial ELF port. 
This is a direct port of the new PE/COFF linker to ELF.

It can take a single object file and generate a valid executable that executes at the first byte in the text section.
