Building libjpeg-turbo with LTO
...lso contains some native objects
and thus had a non-zero symbol table. I created a version of libjpeg.a
using the system library and containing only the bitcode objects, and
confirmed it links fine with lld (the native objects weren't needed in this
case). BTW this is the code in ELF/Driver.cpp LinkerDriver::addFile.
Would it be possible to extend the hack in lld to handle cases like this
with some bitcode objects and some non-bitcode objects, so that the bitcode
objects are not simply ignored?
Thanks,
Teresa

...t; translates all arguments into the MSVC style and then invoke the COFF

That should work, if I am understanding this correctly I can create an
argument parser (probably partially based on the ELF one) then I can set
the data in the COFF Config object and call COFF LinkerDriver::run etc
directly from that?
This proposal is for generally moving code from lld into llvm that could be
part of lib.exe / dlltool, what are your thoughts here?
