in reducing the overall memory requirements of the project. However, problems can arise
if a noncontiguous segment is copied from one space to another using the
COPY command.
The linker issues a warning if it is asked to COPY any noncontiguous segment.
If SPLITTABLE is not specified for a given segment, the linker allocates the entire seg-
ment contiguously.
The SPLITTABLE command takes precedence over the ORDER and SEQUENCE com-
mands.
By default, ZDS II segments are nonsplittable. When multiple segments are made splitta-
ble, the linker might reorder segments regardless of what is specified in the ORDER (or
SEQUENCE) command. In this case, you must perform one of following actions:
•
Modify the memory map of the system so there is only one discontinuity and only one
splittable segment in which case the ORDER command is followed.
•
Modify the project so a specific ordering of segments is not needed, in which case
multiple segments can be marked splittable.
Syntax
SPLITTABLE segment_list
Example
SPLITTABLE CODE, ROM_TEXT
UNRESOLVED IS FATAL
The UNRESOLVED IS FATAL command causes the linker to treat undefined external sym-
bol warnings as fatal errors. The linker quits generating output files immediately if the
linker cannot resolve any undefined symbol. By default, the linker proceeds with generat-
ing output files if there are any undefined symbols.
Syntax
