[Qemu-devel] [PATCH] target-i386: Fix regression with maxsd SSE2 instruction v2

2011-11-08 Thread Jason Wessel
The maxsd instruction needs to take into account the sign of the numbers 64 bit numbers. This is a regression that was introduced in 347ac8e356 (target-i386: switch to softfloat). The case that fails is: maxsd %xmm1,%xmm0 When xmm1 = 24 and xmm0 = -100 This was found running the glib2 binding
