Example usage
=============
To build and run a sample tool:

cd SimpleExamples
make opcodemix
../Bin/pin -t opcodemix -- /bin/ls

This will instrument and run /bin/ls, the output for this tool is in opcodemix.out.


Restrictions
============
The version of the compiler you use to build a tool must be compatible with the pin kit. Gcc 3.2 and 3.3 compilers require a gcc3.2 kit. Gcc 3.4 requires a gcc3.4 kit, and Gcc 4.0 and later requires a gcc4.0 kit. This only applies to the compiler used to build a tool; the application can use any compiler.

Position independent executables are not supported.

To use pin on a multithreaded program use the -mt switch. This switch won't be necessary in the future.


Additional information for using Pin on the Intel Mac
=====================================================
Due to a security check on MacOS-X, you need to apply the following 2 commands to the Pin executable before the first time you use it:
	chgrp procmod Bin/pin
	chmod g+s Bin/pin

Note that you need the root permission to run the above 2 commands. Once you have done this, you can run Pin as a regular user.



Modifications to the APIs
=========================

  May 31, 2006: The analysis argument abstractions IARG_SYSCALL_RESULT and 
		IARG_SYSRET_REFERENCE have been removed.  A new analysis argument
		abstraction, IARG_SYSRET_ERRNO, has been added.  This abstraction
		will contain the error number from the system call.  The analysis
		argument abstraction IARG_SYSRET_VALUE has been modified.  It will
		still contain the return value when the system call is successful.
		However, if the system call is unsuccessful, it will contain -1.
		These abstractions are not supported on Windows.
