// When specifying the segment placement using the -P instead of the -Z

// option, the linker is free to split each segment into its segment parts

|
// and randomly place these parts within the given ranges in order to
|

|
// achieve a more efficient memory usage. One disadvantage, however, is
|

|
// that it is not possible to find the start or end address (using
|
||
|
|
// the assembler operators .sfb./.sfe.) of a segment which has been split
|

// and reformed.
