[Qemu-devel] [PATCH] Bug in target-i386/helper.c:helper_fxam_ST0

2006-06-19 Thread Julian Seward
I've been doing some instruction set testing on i386-softmmu, with the aim of seeing if I can find any anomalies which might be the cause the of Win2K SP4 installation failure. helper_fxam_ST0 doesn't correctly distinguish infinities from nans, and thereby causes programs that use the x86 'fxam'
