[Bug 1881249] [NEW] CPU fetch from unpopulated ROM on reset


From: Philippe Mathieu-Daudé
Subject: [Bug 1881249] [NEW] CPU fetch from unpopulated ROM on reset
Date: Fri, 29 May 2020 07:47:40 -0000

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
