Sourcery G++ Lite includes a simulator that you can use on the host system to run programs compiled for the target system. Since you do not need target hardware, this is the easiest way to try out Sourcery G++.
To use the simulator run:
> mips-sde-elf-run factorial
You should see the expected output:
factorial(0) = 1 factorial(1) = 1 factorial(2) = 2 factorial(3) = 6 factorial(4) = 24 factorial(5) = 120 factorial(6) = 720 factorial(7) = 5040 factorial(8) = 40320 factorial(9) = 362880
You can also use the simulator to execute target programs when debugging with GDB. See Section 4.4, “Running Applications from GDB” for more information.
The simulator supports the MIPS32r2 instruction set, including the MIPS16e, MIPS DSP and DSP Revision 2, SmartMIPS, and MIPS-3D ASEs. It can also emulate earlier variants of the MIPS architecture.
