drrun on SPEC CPU® 2017

[Chiao-Ying Lin]

Hi all,

I am a new user of dynamorio, and I am now using drrun to study some benchmarks from SPEC CPU® 2017. 

I am now using the following command in runcpu:

/home/ubuntu/dynamorio/build/bin64/drrun -c  /home/ubuntu/dynamorio/build/api/bin/libinscount.so -- \

/home/ubuntu/spec2017/bin/specperl -I"${_bin}/common" -I"${_bin}/${_lib}" -I"${_bin}" -I"${_bin}/lib" "${_bin}/${_loc}/${_tool}" $*

but this would fail at building the benchmark with the following message:

======================================================================

Client inscount is running

/usr/bin/ld: cannot find Instrumentation results: 30733113 instructions executed: No such file or directory

/usr/bin/ld: cannot find : No such file or directory

/usr/bin/ld: cannot find Instrumentation results: 3342562 instructions executed: No such file or directory

/usr/bin/ld: cannot find : No such file or directory

/usr/bin/ld: error: could not unlink output file

collect2: error: ld returned 1 exit status

=======================================================================

I cannot even tell what the missing file/directory is.

Best regards,

So, from my experience with using SPEC CPU, I typically set a monitor_wrapper in the configuration file so that specinvoke triggers drrun.

For example, take a look at: https://github.com/Dynamic-Rabbits/Taint-Evaluator/blob/81221f74fe643822e231597af9ea803bda4a2f88/experiments/speccpubench/tests/gcc-linux-x86.cfg#L64

Furthermore, information on monitor wrappers can be found here: https://www.spec.org/cpu2017/Docs/monitors.html#monitor_wrapper

Cheers,

John Galea
