I am using pin to build a mapping from instructions to basic blocks. Is it possible to do this statically? ManualExamples/staticcount.C has a comment which...
Hi, Would it be possible to count/trace only user level instructions (ie. exclude system calls) using pin ? I use kit 0.171 on the itanium. Thanks, Pradeep...

Pradeep: As far as I know pin does not follow system calls, e.g. it will not instrument the kernel. Do you want to actually exclude the syscall *instruction*...

In your example, the /bin/ls program scans the directory. In between the two invocations of /bin/ls, you are adding a new file to the directory. This may...
You can do this by instrumenting the instructions that look like system calls (depends on the architecture you are using). Insert one call with IPOINT_BEFORE...
When using RTN_Open, I believe every RTN contains a single BBL, and that BBL contains all the instructions, even if there are control flow instructions. As it...

Hi Is there a way to ensure pin call Fini function even when the application is terminated abruptly, say because of SIGSEV signal? More generally, is there a...
Satish, Pin only calls the Fini after exit system call, and does not provide a way to ensure the Fini is called when the process is terminated another way. You...
