Using pin to attach to a process

[morca]

I am using a custom tracer which is working with pin tool. The format is

./pin-3.10/pin -t tracer/obj-intel64/champsim_tracer.so -o ~/traces/ls.trace -s 100000 -t 2000000 -- /bin/ls

where -s is the number of instructions to skip and -t is the number of instructions to be trace. The format is similar to the pin usage

Usage: pin [OPTION] [-t <tool> [<toolargs>]] -- <command line>

Thing is that, pin can be used to attach to a process. But when I use that, I get the usage output which means some options are incorrect.

 ./pin-3.10/pin -t tracer/obj-intel64/champsim_tracer.so -pid 1094 -o run.trace -s 10000 -t 10000000
E: Missing application name
Pin: pin-3.10-97971-c5e41af74

Usage: pin [OPTION] [-t <tool> [<toolargs>]] -- <command line>
Use -help for a description of options

Is this a problem with pin or the custom tracer tool? It seems that applying command line is mandatory in pin.

Hello,

Let me re-direct you to Pin tool support: https://software.intel.com/en-us/articles/pin-a-dynamic-binary-instrumentation-tool

"Technical Support
