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 -------------- next part -------------- An HTML attachment was scrubbed... URL...

what C code would produce the following when soft float is enabled? (RTLIB::UO_F32, "__unordsf2"); (RTLIB::UO_F64, "__unorddf2"); (RTLIB::O_F32, "__unordsf2"); (RTLIB::O_F64, "__unorddf2"); tia. reed
