I wish to profile CPU (sample if possible), with as small a performance impact as possible (hence similar to GCC's -pg), binaries compiled with Clang. Is there an alternative that uses instrumentation of the code, or produces output similar to gprof?

I received a good answer on the Clang mailing list. To summarize, the use of Google Performance Tools was the best fit.
