Another clarification I meant to initially convey, so one more time:
Will the content of SHT_SYMTAB always contain the all the same symbols found in SHT_DYNSYM and more symbol (symbols that aren't required by the dynamic loader)? Or do the symbols for the dynamic loader only get put into the SHT_DYNSYM sections, and any other symbols get put into the SHT_SYMTAB sections?
Shouldn't we just parse the SHT_SYMTAB sections and fall back to the SHT_DYNSYM section(s) if there are no SHT_SYMTAB sections?
