Simon Atanasyan 0d5e1b753e [ELF] Do not keep STT_FILE symbols in the symbol table 
STT_FILE symbols usually contain source file names. It is redundant
to keep this information in the output file.

README.md

The New ELF Linker

This directory contains a port of the new PE/COFF linker for ELF.

Overall Design

See COFF/README.md for details on the design. Note that unlike COFF, we do not distinguish chunks from input sections; they are merged together.

Capabilities

This linker can link LLVM and Clang on Linux/x86-64 or FreeBSD/x86-64 "Hello world" can be linked on Linux/PPC64 and on Linux/AArch64 or FreeBSD/AArch64.

Performance

Achieving good performance is one of our goals. It's too early to reach a conclusion, but we are optimistic about that as it currently seems to be faster than GNU gold. It will be interesting to compare when we are close to feature parity.
