[Valgrind-users] Pre-instrumented vs JIT instrumentation

[Mike B. <mbr...@vi...>]

I am new to valgrind, but I have used Rational Quantify.  Excuse if this is
a FAQ, but I could not find anything in the FAQ nor in the mailing list
archive.

I am curious why valgrind chooses to instrument on-the-fly every time the
application is executed rather than instrumenting the application ahead of
time and reexecuting the same instrumented executable each time, a la
Quantify.  To my perhaps naive mind it seems like instrumenting on-the-fly
is less efficient.  Can someone lend some insight?
