[Qemu-devel] [PATCH v2 3/5] target-ppc: exception model of 603e inherits from 603 |
Date: |
Tue, 27 Apr 2010 17:31:08 +0200 |
From: Thomas Monjalon <address@hidden>
It appears in the code that the exception handling of 603e is the same as 603.
If there is addon like SRR1[KEY], it is handled without special case for it.
So it could be removed safely.
