This means that, for example, any +instructions following such a symbol will not be disassembled by +@code{@value{objdump}} as it will regard them as data. To change this +behaviour an optional section name can be placed after the symbol name +in the @code{.global} directive. If this section exists and is known +to be a code section, then the symbol will be marked as poiting at +code not data.
