  • Closed as program error.

Error description

  • The XL Fortran compiler is incorrectly flagging an OMP REDUCTION
    statement as an error:
    
     !$omp    reduction(+:x)
    
    
    "tmp.f90", line 12.6: 1515-095 (E) If a variable is specified in
     a REDUCTION clause with a reduction operator or function, any
    use of that variable must be in a reduction statement.
    

Local fix

Problem summary

  • PROBLEM DESCRIPTION:
    XL Fortran diagnoses reduction statements that do not follow
    the forms:
    
    x = x op expr
    x = expr op x   (except for subtraction)
    x = intr(x, expr_list)
    x = intr(expr_list, x)
    
    These forms, however, are not required by the OpenMP
    specification.
    
    USERS AFFECTED:
    Users of XL Fortran with programs containing OpenMP reduction
    clauses that don't follow the forms above.
    

Problem conclusion

  • XL Fortran no longer forces reduction statements to have one of
    the forms above.
    

Temporary fix
