[Valgrind-users] Execution of a dirty helper: atomic?

[Emilio C. <er...@gm...>]

Hi all,

I would like to know if Valgrind assures atomic execution of a dirty
helper. In more detail I am interested in the situation:

---
access to a memory cell
call to a dirty helper X() [inserted by unsafeIRDirty_0_N]
execution of X()
---

Is this executed atomically by Valgrind?
I know that Valgrind serialises execution so that only one thread is
running at a time but this is another problem.

Emilio.
