No, but you can fake it, with a bit of effort:  see percentify() in
Cachegrind for an example.

You can use VG_(sprintf)() and VG_(write)() to achieve this.  See
Cachegrind for some examples.

This primitiveness can be annoying.  Some work is being done towards
allowing Valgrind to use the standard libraries, but it's still a long way
from completion.
