UM013037-1212 Assigning Memory at Link Time
Zilog Developer Studio II – Z8 Encore!
User Manual
281
Although a module can enter and leave a segment many times, each module still has only
one instance of a segment.
•
Origin
When a segment is defined with an origin, the segment becomes an absolute segment,
and the linker places it at the specified physical address in memory.
Assigning Memory at Link Time
At link time, the linker groups those segments of code and data that have the same name
and places the resulting segment in the address space to which it is attached. However, the
linker handles relocatable segments and absolute segments differently:
•
Relocatable segments
If a segment is relocatable, the linker decides where in the address space to place the
segment.
•
Absolute segments
If a segment is absolute, the linker places the segment at the absolute address specified
as its origin.
At link time, you can redefine segments with the appropriate linker commands. For more
information about link commands, see the
Linker Commands section on page 347.
Output Files
The assembler creates the following files and names them the name of the source file but
with a different extension:
•
<source> .lst contains a readable version of the source and object code generated by
the assembler. The assembler creates <source> .lst unless you deselect the Generate
Assembly Listing Files (.lst) checkbox in the Assembler page of the Project Set-
tings dialog box. See the Generate Assembly Listing Files (.lst) section on page 80.
•
<source> .obj is an object file in relocatable OMF695 format. The assembler creates
<source> .obj .
