[LLVMdev] Floating point comparison doubt

[Sachin.Punyani at microchip.com]

Hi,

 

In unordered floating point comparison before making a call for
comparison proper one node called UO_F32 is generated. In targets this
node is replaced with a call to __unordsf2.

 

My doubts here

1)  What are these UO_F32 and O_F32 nodes for?

2)  What is this function (__unordsf2) supposed to do?

 

Regards

Sachin
