See answer to 2. mcount() and -p is orthogonal to valgrind profiling 
technique.

Valgrind uses different profiling technique (dynamic code 
translation/instrumentation), whereas profiling with -p inserts special 
call at the beginning (and end, I assume) of every function at compile 
time. -p is used if compiling with profile=1. Valgrind does not need 
recompilation.
