/sys$common/syshlp/helplib.hlb MACRO, /MIGRATION, Compiler Directives, .SYMBOL ALIGNMENT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    This directive associates an alignment attribute with a symbol
    definition for a register offset. You can use this directive
    when you know the alignment of the base register. This attribute
    guarantees to the compiler that the base register has the same
    alignment, which enables the compiler to generate optimal code.

    Format

      .SYMBOL_ALIGNMENT  argument-list
