Subject: [Qemu-devel] Updated PATCH: solaris-softloat.diff
Date: Fri, 28 Apr 2006 13:04:23 -0400 [thread overview]
Message-ID: <3686352.1146243863904.JavaMail.root@eastrmwml05.mgt.cox.net> (raw)
[-- Attachment #1: Type: text/plain, Size: 225 bytes --]
After figuring out there was some typos in fpu/softfloat-native.h, this patch has been
reworked to more closely mirror the BSD structure.
This is against the current CVS post pbrook's patching of fpu/softfloat-native.h
