Linker and Utilities
5.8.2.5 Segment Listing
The class listing in the map file is followed by a listing of segments. A segment is conceptual
grouping of contiguous psects, and are used by the linker as an aid in psect placement. There is no
segment assembler directive and segments cannot be controlled in any way.
The name of a segment is derived from the psect in the contiguous group with the lowest link address.
This can lead to confusion with the psect with the same name. Do not read psect information from
this section of the map file.
5.8.2.6 Unused Address Ranges
The last of the memory summaries Just before the symbol table in the map file is a list of memory
which was not allocated by the linker. This memory is thus unused. The linker is aware of any
memory allocated by the code generator (for absolute variables), and so this free space is accurate.
and is followed by a list of classes and the memory still available in each class defined in the program.
If there is more than one range in a class, each range is printed on a separate line. Any paging
boundaries within a class are ignored and not displayed in any way.
space in a memory area is not simply the addition of the size of all the ranges indicated. For example
if there are two classes the cover the RAM memory — RAM and BANKRAM — and the first 100h
out of 500h bytes are used, then both will indicate 000100-0004FF as the unused memory.
5.8.2.7 Symbol Table
The final section in the map file list global symbols that the program defines. This section has a
heading:
and is followed by two columns in which the symbols are alphabetically listed. As always with the
linker, any C derived symbol is shown with its assembler equivalent symbol name. The symbols
listed in this table are:
This section is heralded by the line that contains the headings:
Typically this section of the map file can be ignored by the user.
This section follows the heading:
Note that classes often define memory that is also covered by other classes, thus the total free
