• Closed as program error.

Error description

• When compiling at -O4 or higher, or explicitly using -qipa, the
  compiler is returning an error code of 0 when attempting to link
  with a non-existent library.
  
  
  $ cat test.c
  int main (void)
  {
     return 0;
  }
  $ xlc -O4 test.c -lnoexist
  1586-403 (E) Library file "noexist" not found.
  $ echo $?
  0
  

Local fix

• Use a lower optimization level.
  

Problem summary

• USER AFFECTED:
  Users who turn on IPA transformations with -qipa, -O4 or
  -O5 and specify libraries which do not exist.
  
  PROBLEM DESCRIPTION:
  The IPA step is returning 0 when encountering this error.
  

Problem conclusion

• The IPA step now returns a non-zero error code:
  
  $ xlc test.c -lnoexist -O4
  1586-403 (U) Library file "noexist" not found.
  $ echo $?
  1
