question about libtool

[Wayne Christopher]

Dear libtool maintainers,

I'm trying to use libtool to hide all but a few symbols in a .o file
that I have created with ld -r.  I use the command:

libtool --mode=link \
        ld -r -u export_1 -o output_file.o \
        input_file.o -export-symbols-regex export_.\* 

but in output_file.o there are lots of T and D symbols that don't match
the pattern I specified and aren't mangled in any way.  Is this the
right way to do it?  I can't tell from reading the documentation how
this is supposed to work.

Thanks in advance,

        Wayne
