<pre>% cat sym.c
void f() {}
% clang -fPIC -c sym.c
% ld.lld -shared --defsym=g=f -o libsym.so sym.o
% nm -D libsym.so
0000000000001000 T f
0000000000001000 T f
We end up with two f's in the symbol table rather than an f and a g. This
appears to be a known issue; r306036 corrected it, but it had to be reverted in
r307110 because of PR33635.
The issue I have with this is that it prevents clients of the library from
using the aliased name, which limits the usefulness of --defsym quite a bit.
Both bfd and gold handle this correctly.</pre>
