Subject: [Qemu-devel] [patch] Arm/Thumb entry points
Date: Fri, 3 Feb 2006 15:14:13 +0000 [thread overview]
Message-ID: <200602031514.14309.paul@codesourcery.com> (raw)
The patch fixes a bug in the arm usermode emulation. The CPU wasn't being
correctly initialized when the entry point is a Thumb function.
