Subject: [Qemu-devel] [PATCH 0/4] target-i386: Fix regressions introduced by the switch to softfloat
Date: Sat, 7 Jan 2012 21:09:34 +0100 [thread overview]
Message-ID: <1325966978-940-1-git-send-email-aurelien@aurel32.net> (raw)
Since commit 347ac8e35661eff1c2b5ec74d11ee152f2a61856 which switched
target-i386 to softfloat, a few SSE instructions are not working
correctly anymore. It's especially noticeable on linux/x86-64 as SSE is
used default for floating point computation. For example GDM from Debian
Lenny is not usable anymore, it displays all the graphical elements at
the wrong place.
This patch series is an attempt to fix that, and it's probably a good
idea to apply it to the stable branch.
Aurelien Jarno (4):
target-i386: fix {min,max}{pd,ps,sd,ss} SSE2 instructions
target-i386: fix round{pd,ps,sd,ss} SSE2 instructions
target-i386: fix dpps and dppd SSE2 instructions
target-i386: fix SSE rounding and flush to zero
