I assume by "variables" you mean variables in the programming language you are using, eg. C. However, Valgrind works at the binary level, so its analysis is on registers, memory locations, instructions, etc -- machine-level things, rather than programming language things. You can map from the machine level back to the language level using debugging information -- that's how the various tools report line numbers, for example. But mapping back to variables is harder. There might be some capability for it in Valgrind's libraries, but I'm not certain. Doing analysis that relies heavily on language-level information is difficult in Valgrind.
