IV83830: SQRTF UNDEFINED SYMBOL ERROR WHEN USING GCC APPLIES TO AIX 7100-03

APAR status

• Closed as program error.

Error description

• When IV77723 is applied, a program calling sqrtf() in
  libm.a will receive an 'undefined symbol' error when
  compiling with gcc.
  
  For example, tst.c is:
  
  #include<stdlib.h>
  #include<stdio.h>
  #include <math.h>
  int main() {
          float value=4;
          sqrtf(value);
  }
  
  Although using xlc works fine, gcc will give:
  
  # gcc -lm tst.c
  ld: 0711-317 ERROR: Undefined symbol: .sqrtf
  

Local fix

Problem summary

• sqrtf wont throw Undefined symbol error when compiled with gcc
  

Problem conclusion

• Put back changes for frexpf, ldexpf and sqrtf missing.
  

Temporary fix
