LI77428: INTERNAL COMPILER ERROR IN XLFCODE AT -O3

Subscribe

You can track all active APARs for this component.

APAR status

  • Closed as program error.

Error description

  • The compiler produces an internal compiler error in xlCcode when
    a large test case is compiled with -O3 due to the activation of
    -qhot.
    

Local fix

  • Use -O3 -qnohot as a workaround.
    

Problem summary

  • USERS AFFECTED:
    Potentially users of -O2 and up, compiling very large source
    programs are affected by this issue.
    
    PROBLEM DESCRIPTION:
    The compiler produces an internal compiler error when compiling
    with higher optimization levels.
    

Problem conclusion

  • The compiler has been fixed to increase capacity of some
    optimizations to avoid internal error on large functions at -O2
    and up.
    

Temporary fix
