What about attaching GCC's intermediate representation to the executable
file? This will allow dynamic recompilation if
a) the assigned cache size varies during operation
b) the ratio of core speed to memory speed changes
c) the cache associativity changes
This recompilation can be done on another core or even processor and
will not decrease speed of the current executable.
If the results of this recompilations are attached as well then it only
has to be done once.
Objections?

Tobias
