LI76956: CONST TYPE QUALIFIER WITH VECTOR4DOUBLE ERROR

November 2012 Update for XL C/C++ for Blue Gene/Q, V12.1
February 2013 Update for XL C/C++ for Blue Gene/Q, V12.1

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
