Enables contiguous block output over an area of source code.
Output data simply has an address and value. This means that if you skip a block of data (for example, via the .org directive) without writing anything in the intervening space the object file will have holes in it.
Some output formats, such as Intel HEX files, accomodate this problem by giving each sequence of data an address field. Other output writers, such as the raw writer plugin, ignore the missing data.
This plugin will automatically add explicit output data to fill the holes. It will use the current empty fill value.
