APAR status

  • Closed as program error.

Error description

  • In the compiler reference for xlC __bcopy is defined as
    
    void __bcopy(const void* src, void* dest, size_t n);
    
    However the following errors are observed:
    
    : 1540-0256 (S) A parameter of type "char *" cannot be
    initialized with an expression of type "short *".
    : 1540-1205 (I) The error occurred while converting to parameter
    1 of "__bcopy(char *, char *, int)".
    
    which is due to that in /usr/vacpp/include/builtins.h __bcopy()
    is defined as
    
    __builtinDecl void __bcopy(char *, char *, int);
    

Local fix

  • N/A
    

Problem summary

  • USERS AFFECTED:
    Users of the built-in function __bcopy are affected by this
    issue.
    
    PROBLEM DESCRIPTION:
    Declaration of built-in function __bcopy differs from the
    documentation.
    The documentation states the parameter types to be void*, void*
    and size_t, while it is actually declared to take char*, char*,
    and int.
    This results in a severe error for valid (according to the
    documentation) calls to __copy with non char pointer argument
    types.
    

Problem conclusion

  • The declaration of __bcopy has been updated in the C and C++
    front ends to match with the documentation.
    

Temporary fix
