RE: [Xen-ia64-devel] 2 LTP math cases failed in xen0

["You, Yongkang" <yongkang.you@xxxxxxxxx>]

Hi Dan,

I am not sure about how to check if those math cases are using FPSWA. I greped 
the key word in float math cases, but nothing found.

1 information is that these 2 cases (float_exp_log and float_power) can pass in 
the VTi and IA32 testing. I paste the float codes in the attachment tar ball. 
Hope it can give some help. If need any information, please let me know.

Best Regards,
Yongkang (Kangkang) 永康
