I64 and Alpha systems. Declares universal symbols in shareable
    images.

    Format

      SYMBOL_VECTOR=([alias/]name=entry-type[,...])

1  –  Option Values

 alias

    Optionally specifies an alias name for the symbol you want to
    declare universal. When specified, the alias name appears in the
    global symbol table (GST) of the image and values associated with
    the name specified in the symbol-name parameter appear in the
    symbol vector of the image.

    Note that you can specify alias names only for symbol vector
    entries declared using the DATA or PROCEDURE keywords. For more
    information about symbol vector entry types, see the following
    table.

 name

    Specifies the name of the symbol or the name of a program section
    in the shareable image that you want to declare universal.

 entry-type

    Specifies the type of the symbol vector entry. The following
    table lists the types of symbol vector entries supported by the
    linker along with the keyword you use to specify them:

    Keyword          Function

    DATA             Creates a symbol vector entry for data
                     (relocatable or constant). The linker creates an
                     entry for the symbol in the GST of the shareable
                     image.
    PROCEDURE        Creates a symbol vector entry for a procedure
                     and creates an entry for the symbol in the GST
                     of the shareable image.
    PRIVATE_DATA     Creates a symbol vector entry for data; however,
                     the linker does not create an entry for the data
                     in the GST of the shareable image. Thus, the
                     symbol is not available for other modules to
                     link against.
    PRIVATE_         Creates a symbol vector entry for a procedure;
    PROCEDURE        however, the linker does not create an entry
                     for the procedure in the GST of the shareable
                     image. Thus, the symbol is not available for
                     other modules to link against.
    PSECT            Creates a symbol vector entry for a program
                     section and creates an entry for the program
                     section in the GST of the shareable image.
    SPARE            Use this keyword to create a placeholder.
                     SPARE allows you to preserve the order of the
                     symbol vector entries when you need to create an
                     upwardly compatible shareable image. The SPARE
                     keyword is used alone; it is not preceded by a
                     symbol name and equal sign.
