LDF Commands
Page overlays that appear in the
ory must first be described in a
must contain a leading digit to indicate the page number.
For example, the memory corresponding to
DSP could appear in the
seg_page4 { TYPE(PM RAM) START (0x42000) END(0x43FFF) WIDTH(24)}
According to this definition, to operate as both the "run-time" memory
for all of the paged overlays and the "live" memory for
memory segment has page value 0, and the start address for this section is
0x2000. In implementations where no internal memory is at that address
(for example, in the ADSP-2186 DSP), the linker generates an error for
the page specified to "live" at that address.

PAGE_OUTPUT()

L
The
PAGE_OUTPUT()
tures, such as ADSP-218x DSPs.
Use the
PAGE_OUTPUT()

OVERLAY_OUTPUT
tion in the

PLIT{}

The (procedure linkage table) command in an
PLIT{}
assembly instructions that handle calls to functions in overlays. The
commands provide a template from which the linker generates
PLIT{}
assembly code when a symbol resolves to a function in overlay memory.
