Subject: [Qemu-devel] [PATCH for-1.5?] target-ppc: Drop unnecessary dynamic cast in ppc_env_get_cpu()
Date: Fri, 10 May 2013 16:39:59 +0200 [thread overview]
Message-ID: <1368196799-19982-1-git-send-email-afaerber@suse.de> (raw)
A transition from CPUPPCState to PowerPCCPU can be considered safe,
just like PowerPCCPU::env access in the opposite direction.
This should slightly improve interrupt performance.
