Debugtrace is a tool for printing execution traces that are helpful for debugging. It can generate instruction or call traces. It shows every instruction as it is executed, the values of registers that are written, and the memory that is read and written. It uses instrumentation rather than the debugging API, so it is much faster than doing the same thing with gdb. You can customize it to your own debugging needs. The tool works on Linux ARM, IA32, and EM64T.

Pin is an ATOM-like instrumentation tool for Linux executables. It allows arbitrary code (written in C or C++) to be injected at arbitrary places in an executable. Unlike Atom, Pin does not perform the instrumentation statically by rewriting the executable, but rather dynamically by adding instrumentation while the executable is running. Currently supported platforms include IA-32, Intel Xscale, and Itanium processors.
