2. The gdb56 debugger operates with COFF format “.cld” files generated by the
DSP56000 COFF Assembler and Linker programs. The gdb56 subdirectory
“m56kinc” contains header files which define the COFF structures used by gdb56
as well as other device-specific header files.
3. The gdb56 evaluator and display routines have been enhanced to handle the 48 bit
long values and special format floating-point values used by the DSP56000.
4. The simulation is able to halt at breakpoints without actually breaking the pipeline
activity of the device and without actually inserting breakpoint code into the device
memory. As a result, the simulator can maintain an accurate record of the device
execution time regardless of the number of inserted breakpoints. The cycle count is
maintained in the variable $cyc.
5. The normal gdb program uses.gdbinit as the default initialization file at start-up
whereas
gdb56
uses.gdbinit56.
