$COMMAND_LINE_OBJECTS
macro, which expands at the linker command line into the list of
input files. Each linker invocation from the VisualDSP++ IDDE
has a command-line equivalent. In the VisualDSP++ IDDE,
$COMMAND_LINE_OBJECTS

Note: The order in which the linker processes object files (which
affects the order in which addresses in memory segments are
assigned to input sections and symbols) is determined by the listed
order in the

The VisualDSP++ IDDE generates a linker command line that lists
objects in alphabetical order. This order carries through to the
$OBJECTS
any desired order. Instead of using default macros such as
$OBJECTS
explicit object names.
The following examples are functionally identical.

physical memory and connects the program to the target system.
Its arguments partition the memory into memory segments. Each
memory segment is assigned a distinct name, memory type, a start
and end address (or segment length), and a memory width. These
names occupy different namespaces from input section names and
output section names. Thus, a memory segment and an output sec-
