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 executed, 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.
