(DIANA) A formerly
de facto standard
intermediate language for
Ada programs, developed by Goos
and Wulf at
CMU in January 1981. DIANA is an attributed tree representation, with an abstract interface defined in
Interface Description Language (Nestor, Lamb and Wulf, CMU,
1981; Snodgrass(?), 1989(?)). DIANA resulted from a merger of
AIDA and
TCOL.Ada. At the present (2001) it is no longer
used by the major ADA compilers
["DIANA - An Intermediate Language for Ada", G.T. Goos et al,
LNCS 161, Springer 1983].
