Performance measuring with prof

Is there a way to run linux's prof in a way equivalent to what a program with -gprof would do? I know wouldn't be exact, but only statistically correct.

I'm basically looking for a way to do a gprof-like analysis on a C/C++ program that includes debug symbols, but without recompiling it.

I'm very satisfied lately by CPU profiler of the Google performance tools. Programs basically run at undistorted normal speed under it. No recompilation is required, linking against a special libraries is recommended but using LD_PRELOAD is also possible in most cases.
