And that is exactly as should be: a core dump represents the execution state of a user program, it has nothing to do with the machine it was generated on; it even is possible to restart a core dump generated on e.g. an e500 on a 970, as long as it doesn't use facilities (e.g., SPE) that the latter processor / execution environment doesn't provide. > Is that a misfeature of GDB that we even have to > worry about this, or some noble plus point of a unified ISA?
