/* This is a BFD backend which may be used to write binary objects.
It may only be used for output, not input. The intention is that
this may be used as an output format for objcopy in order to
generate raw binary data.
This is very simple. The only complication is that the real data
will start at some address X, and in some cases we will not want to
include X zeroes just to get to that point. Since the start
address is not meaningful for this object file format, we use it
instead to indicate the number of zeroes to skip at the start of
the file. objcopy cooperates by specially setting the start
address to zero by default. */
