<pre>The Microsoft tools will make a DLL that exports "@foo@8" out of the following
.c file and .def file:
$ cat foo.c
int __fastcall foo(int x, int y) { return x + y; }
$ cat foo.def
EXPORTS
foo
# Use a 32-bit compiler
$ cl -c foo.c && link -dll -out:foo.dll foo.obj

Creating library foo.lib and object foo.exp
$ llvm-nm foo.lib
...
foo.dll:

If you substitute lld-link into the above command, I get:
C:\src\llvm-project\build\bin\lld-link.exe: warning: <root>: undefined symbol:
_foo
error: link failed</pre>
