[Qemu-devel] [PATCH v3 5/7] softfloat: Drop [s]bits{8, 16, 32, 64} types


From: Andreas Färber
Subject: [Qemu-devel] [PATCH v3 5/7] softfloat: Drop [s]bits{8, 16, 32, 64} types in favor of [u]int{8, 16, 32, 64}_t
Date: Sat, 18 Dec 2010 17:25:29 +0100

They are defined with the same semantics as the POSIX types,
so prefer those for consistency. Suggested by Peter Maydell.

v3:
* Initial.
