   One or more of the symbolic arguments listed in the following
   table:

   Option         Description

   GRANULARITY    Preserves the rules of VAX granularity of writes.
                  Specifying .PRESERVE=GRANULARITY causes the
                  compiler to use Alpha Load-locked and Store-
                  conditional instruction sequences or the Itanium
                  compare-exchange (cmpxchg) instruction in code it
                  generates for VAX instructions that perform byte,
                  word, or unaligned longword writes.
   ATOMICITY      Preserves atomicity of VAX modify operations.
                  Specifying .PRESERVE=ATOMICITY causes the
                  compiler to use Alpha Load-locked and Store-
                  conditional instruction sequences or the Itanium
                  compare-exchange (cmpxchg) instruction in code
                  it generates for VAX instructions with modify
                  operands.
