Parameters

 

argument-list

   One or more of the arguments listed in the following table. For
   each argument, you can specify one or more registers:

   Option       Description

   aligned=<>   Declares one or more registers to be aligned on
                longword boundaries.
   unaligned=<> Declares one or more registers to be unaligned.
                Because this is an explicit declaration, this
                unaligned condition will not produce a fault at
                run time.
   read=<>      Declares one or more registers, which otherwise the
                compiler could not detect as input registers, to be
                read.
   written=<>   Declares one or more registers, which otherwise the
                compiler could not detect as output registers, to be
                written to.
