NAME
run--Simulator front-end
SYNOPSIS
run [-v] [-p freq] [-m memory] [--sysroot filepath] program
DESCRIPTION
Use `run program' to execute a binary by interpreting machine instructions on your host computer.
run is the same emulator used by GDB's `target sim' command. You can run it directly by executing run if you just want to see your program
execute, and do not need any debugger functionality. You can also use run to generate profiling information for analysis with gprof.
OPTIONS
-v Verbose output. Display the name of the program to run before execution; after execution, display the number of instructions exe-
cuted, the number of machine cycles emulated, the number of pipeline stalls, the real time taken, the emulated execution time taken,
and a summary of how much profiling information was generated.
-p freq
Generate profile information (for use with gprof). freq is the profiling frequency. Write the profiling information to a file
called gmon.out.
-m memory
Set the memory size for the emulated machine to two to the power memory. The default value is 19, emulating a board with 524288
bytes of memory.
--sysroot filepath
Prepend filepath to all simulator system calls that pass absolute file paths. Change working directory to filepath at program
start. Not all simulators support this option; those that don't, will ignore it.
