Hi, I am writing a pintool that outputs the instruction pointer of some instructions. Now I need to find out the source lines that these instruction pointers...
Greeting, I'm working on getting indirect call value. From the instructions such as, call dword ptr ss[ebp+0x8] jmp dword ptr ds[0x6ed2fc] I need to get the...
I need to get the value in segment registers as described above. Actually, you don't. You can use IARG_MEMORY_READ_EA to get the linear address of the...
Hi I want a clarification on the instrumentation process of PIN. PIN rewrites the binary with appropriate instrumentation calls, Are these system calls?, How...
Greeting, pinheads I would like to ask you something that bring me more confusions. The below code is the snapshot I captured using OllyDbg.exe on ALZip.exe, a...

Hello, A tool I wrote about weeks ago ceased to function correctly recently. I suspect it is a gcc version issue. For right now, my gcc is 4.2.4. The specific...
Hi, I'm having trouble with a simple instrumentation using PIN_SetContextReg : the change in the register doesn't seem to be effective, the eax register stay...
The documentation for IARG_CONTEXT is a little confusing, and will be fixed in our next Pin kit. Here is the new documentation: Type: "CONTEXT *". Handle to...
BBL_Address(). Pin discovers each BBL as the program runs, so it never knows the total number BBL's in your program. Therefore, there is no API to ask for the...
We are not aware of any problems with gcc 4.2.4, but I don't think we test with that particular release. We test with other 4.2.x and 4.3.x gcc releases. I...
Hi, Can I attach Pin to a running process on Windows XP/Vista using the command-line pin -pid <pid> -t mytool.dll and expect profiling to be done? Can I do...
