Re: redefine symbol names in shlib?

OK, just checking. Is there a good theoretical or practical reason why
objcopy *shouldn't* handle dynamic syms, transparently?
An option should do one thing. What should --redefine-sym do for an
executable with both a normal symbol and a dynamic symbol table? I
don't think it should change the symbol in both tables. If it did,
there would no way to change the symbol in only one table.
More seriously, renaming a dynamic symbol probably won't work
correctly. If you rename a dynamic symbol, you really need to
recompute the .hash section. Otherwise, the dynamic linker won't find
the dynamic symbol. But currently the .hash section is computed only
by the linker when the executable or shared library is created. It is
not computed by objcopy.
