[PATCH] D39348: Implement --just-symbols.

[Chih-Mao Chen via Phabricator via llvm-commits]

PkmX added a comment.

If the only input file is specified as the argument of `--just-symbol`, lld will error out (`ld.bfd` accepts this):

  $ riscv64-unknown-linux-gnu-ld.lld -r --just-symbols foo.o -o bar.o
  riscv64-unknown-linux-gnu-ld.lld: error: no input files
  riscv64-unknown-linux-gnu-ld.lld: error: target emulation unknown: -m or at least one .o file required

I'd suggest adding a separate kind of `InputFile` whose symbols only gets added to the symbol table as absolute (but don't add its sections). I have a patch that implements this if you'd like to review it.
