simulating section-gc with ar-archives?

[Adam Megacz]

If I understand correctly, ld will ignore any unreferenced .o's in an
ar-archive when linking. So if foo.a contains bar.o and baz.o, and
baz.o is never referenced, baz.o will not be included in the final
executable.

Does this mean that you could simulate section-gc by breaking all your
.o's up so that each file contained exactly one section, wrapping it
all up in a .a, and linking that?

I'm trying to get section-gc to work on win32/PE.
