[Main] Title=__ld_data_start See Also=symbols_ld_data_end: __ld_data_end, symbols_ld_data_size: __ld_data_size [Top] This built-in symbol represents the starting address of the data section, if the program does not mix text and data (for example if the data is written into an external file). It points to the location behind the last item in the section. If the program does not contain an explicit data section, an error is reported.
