Error description

  • An internal compiler error occurs when compiling code that is
    potentially SIMDizable with optimization enabled.  The
    optimization level used is -O3 and up, implying that the -qsimd
    option is enabled.
    
    The error message output looks like:
    
    1500-004: (U) INTERNAL COMPILER ERROR while compiling
    my_function(double *, char *).  Compilation ended.  Contact
    your Service Representative and provide the following
    information: Internal abort. For more information visit:
    http://www.ibm.com/support/docview.wss?uid=swg21110810
    1586-346 (U) An error occurred during code generation.  The code
    generation return code was 1.
    

Local fix

  • None.  Use lower optimization level.
    

Problem summary

  • PROBLEM DESCRIPTION:
    An internal compiler error is encoutered when compiling with -g
    debug information and optimization enabled.  Internal code
    movement of debug information caused by optimization is putting
    the compiler in an error state.
    
    USERS AFFECTED:
    Users compiling with -g and optimization
    

Problem conclusion

  • The compiler was corrected to avoid the error state.
    

Temporary fix
