Subscribe

APAR status

  • Closed as program error.

Error description

  • Type qualifiers such as const and storage class specifiers such
    as static can appear in any order within a vector4double
    declaration.  If the qualifier is specified after the
    vector4double keyword, the bgxlC C++ compiler invocation is
    encountering an internal compiler error.
    
    
         =====  EXAMPLE  =====
    
    Internal compiler error:
     vector4double const a = vec_lda(i, ptr);
    
    Correct:
     const vector4double aL = vec_lda(i, ptr);
    

Local fix

  • Move qualifer before keyword.
    bgxlc C compiler invocation is not affected.
    

Problem summary

  • PROBLEM DESCRIPTION:
    The data type parsing capability of the compiler was not
    recognizing the const qualifier following the vector4double
    keyword correctly, and was internally saving invalid data.
    
    USERS AFFECTED:
    Users of vector4double data types on BG/Q.
    

Problem conclusion

  • Parser code was corrected to recognize the qualifier following
    vector4double.
    

Temporary fix
