That echoes what I was leaning towards as well. In that case the option can be
made non-LTO specific and just added to AsmPrinter.cpp (perhaps overriding the
field from TargetOptions when specified).
Also, regardless, I don't think there needs to be a field added to the
lto::Config, as that has a different member that is the TargetOptions struct,
which already contains a field for this info and could be filled in as needed.
I'd love to get to a point where compiler FE options like this could all pass
info via the bitcode (e.g. module flags), but we're not there yet. But I don't
know that we need dedicated LLD options for this support in the meantime.
