   3 # If you want to use a custom linker with Cargo, Cargo requires that you
   4 # specify it in Cargo.toml or via the matching environment variable.
   5 # Passing extra options to the linker is possible with Cargo via
   6 # RUSTFLAGS='-C link-args', but testing showed that doing this reliably
   7 # was difficult.
   8 #
   9 # Our solution to these problems is to use this wrapper script.  We pass
  10 # in the LD and the LDFLAGS to use via environment variables.  Note that
  11 # we do *not* quote either MOZ_CARGO_WRAP variable:
  12 #
  13 # * MOZ_CARGO_WRAP_LD is equivalent to CC on Unix-y platforms, and CC
  14 #   frequently has additional arguments in addition to the compiler
  15 #   itself.
  16 # * MOZ_CARGO_WRAP_LDFLAGS contains space-separated arguments to pass,
  17 #   and not quoting it ensures that each of those arguments is passed
  18 #   as a separate argument to the actual LD.
  19 #
  20 # $@ is doubly quoted for the eval. See bug 1418598.
