[OpenRISC] How to pass executable arguments to Or1ksim

[Ziqiang Patrick Huang]

Is there a way to pass executable arguments to Or1ksim ?

Say I have an executable called 'foo' and it takes in a file input.txt,
simply append the file at the end of the command :

sim -f sim.cfg foo input.txt

does not work.

Thanks,

Even if this would be possible, how is your program supposed to be able to
read input.txt?

As far as I know, there is no file support in the or1k toolchain. I
recommend converting your input file to a character array that gets
compiled into your program; it has worked for me on several occasions.

Perhaps it is worth to try ovpsim or the qemu Linux emulation in this case.

Hi Mattew,

Thanks for your reply, when you say converting the input file to a
character array, do you mean actually having the data declared as variables
in the source code, for example, if the input.txt has two columns of
integers, just modify the source code to have two arrays of integers
instead of reading from files.

Thanks,

Hi Stefan,

Thanks for your reply, I think I don't know the simulator enough to answer
your question. I'm just trying to run SPEC in or1ksim, and all the SPEC
benchmarks takes in input files. How should I get around in this situation
? A more general question would be, what standard benchmarks do openrisc
communities use or or1ksim would accept .

Thanks
