Subject: [Qemu-devel] [patch] CPU_DoubleU and soft-float
Date: Sat, 26 Mar 2005 20:53:32 +0000 [thread overview]
Message-ID: <200503262053.32734.paul@codesourcery.com> (raw)
The definition of CPU_DoubleU is incorrect on arm hosts when using
soft-float. In this case "float64" will have host integer word ordering, not
host hardware float ordering.
