+Relocate the @code{Data} section by @var{yyy} from its original address.
+If the object file format provides segment information (e.g.@: @sc{elf}

+Relocate the first segment of the object file, which conventionally
+contains program code, to a starting address of @var{xxx}.  If
+@samp{DataSeg} is specified, relocate the second segment, which
+conventionally contains modifiable data, to a starting address of
+@var{yyy}.  @value{GDBN} will report an error if the object file
+does not contain segment information, or does not contain at least
+as many segments as mentioned in the reply.  Extra segments are
+kept at fixed offsets relative to the last relocated segment.
