// Segment placement - General information
|
|
//
|
|
// All numbers in the segment placement command lines below are interpreted
|
|
// as hexadecimal unless they are immediately preceded by a '.', which
|
|
// denotes decimal notation.
|
|
//
|
|
// 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.
|
|
//
|
|
// When generating an output file which is to be used for programming
|
|
// external ROM/Flash devices, the -M linker option is very useful
|
|
// (see xlink.pdf for details).
