-mcpu=v8 generate SPARC V8 mul/div instructions - needs hardware multiply and divide
-O2 or -O3 optimize code maximum performance and minimal code size
-qleon3std generate LEON3/4 executable without driver manager startup initialization
-qleon3mp generate LEON3/4 Multiprocessor executable (AMP)
4.3.4. Running and debugging with GRMON
Once your executable is compiled, connect to your GR712RC-BOARD with GRMON. The following log shows
how to load and run an executable. Note that the console output is redirected to GRMON by the use of the -u
command line switch, so that printf output is shown directly in the GRMON console.
[andrea@localhost samples]$ grmon -ftdi -u

To debug the compiled program you can insert break points, step and continue directly from the GRMON console.
Compilation symbols are loaded automatically by GRMON once you load the executable. An example is provided
below.

Alternatively you can run GRMON with the -gdb command line option and then attach a gdb session to it. For
further information see Chapter 3 of [RD-7].
