PowerMacs have had Dynamic Recompilation for years now; if
you want to see how good it works (on Mac programs at least),
try out Executer for the PC. It runs Mac 68K programs with
DR and gets VERY good results, similar to what you see
with PowerMac G3 or G4 systems (on a PII or PIII).
Macs have never been big on self-modifying code, and
the segmented nature of 68K programs with seperate data
areas makes DR work VERY well on them.
