Tru64, from the beginning, was LP64. As far as I remember, Solaris 7 was
the first version to support 64-bit hardware, using the same LP64 model.

Whether Solaris had a -taso, I don't know. Tru64 (or was it Digital UNIX
or even OSF/1 AXP?) offered -xtaso, -xtaso_short and -taso to deal with
source code which wasn't ready for true 64. In the xtaso_short mode
pointer size is 32 bits. In the xtaso[_short] mode, the compiler
recognizes and supports (the well known) pointer_size pragmas.
