Hello, 

 

I try to use a Double-precision floating-point custom instruction with a NIOS II.So, I get a problem in 'printf' when I rebuild the retoune __eqdf2() to emulate the floating point operation . So, The attachement figure shows the result.  

 

This problem is not happened when I have rebuilded the others floating-point routines: e.g __nedf2(), __adddf3, __subdf3, ... 

 

I think there is a conflict between libraries (standard floating point library and the new rebuided library). 

 

can someone help me?? 

 

Thank you for all members.
