[Alg] Gebruik stackpointer GPR

[Icelus]

In Dr. Dobb's Journal September 2004 lees ik:

Not only are all eight MMX registers in use, but so too are all eight general-purpose registers - including ESP, since the code requires no stack. Many people don't realize that under Windows it's safe to use ESP as a general-purpose register because the OS switches to a system stack when fielding interrupts and context switching. (Note, though, that the code is no longer multithread-safe unless thread-local storage is used because ESP must be stored somewhere other than the stack so it can be restored at the end of the routine.)

Zelf gebruik ik de stackpointer eigenlijk nooit als GPR.
Is dit ook mogelijk onder Linux (lijkt mij wel)?
