Capturing usage information

I'd like to record the running of a typical program such as Firefox,
GCC, or ffmpeg and capture the calls and arguments to functions like
strcpy() and memcpy(). The idea is to generate a usage profile so we
can tell what standard library functions and what variants (i.e.
aligned/unaligned, small copy/large copy) to attack first.
Does anyone know of existing research with this information, or
existing tools that could capture it?
My fallback is to use a LD_PRELOAD trick to replace the interesting
functions with tracing versions.
