Public bug reported:
Some architectures fetch the $PC/$SP register as vectors in memory, usually ROM.
The CPU reset() handler is called before the ROM code is populated, resulting
in fetching incorrect PC/SP.
Architectures affected:
- M68K
- RX
- ARM M-profile
** Affects: qemu
Importance: Undecided
Status: New
