Which tool(s) do you mean?

valgrind is an "umbrella" program which runs several tools
including memcheck (the default tool), helgrind, cachegrind,
drd, lackey, massif, and a few experimental tools such as
exp-bbv and others.  What you are asking depends on the tool.
In general, the answer is "No", but there may be exceptions
depending on the tool.

By its very nature, memcheck requires instrumenting
EVERY SINGLE INSTRUCTION, and this is IMPOSSIBLE to change.
