Whose historical (perhaps ancient) Ada compiler is not on the list (ignorin= g NYU's AdaEd interpreter that served as some sort of basis for GNAT and ig= noring packaging variants such as EZload of GNAT)? Is it true that absolutely no Ada compiler vendor other than the 3 variants= of GNAT (counting the LLVM one as a limping-along 3rd variant) have achiev= ed the bulk of the Ada2012 feature-set in approximately six years? What disruptors are foreseeable to change any of this significantly? =E2=96=AA=EF=B8=8E fresh new Ada compiler (e.g., Byron) =E2=96=AA=EF=B8=8E drastically-divergent fork of GNAT =E2=96=AA=EF=B8=8E faster Ada-compiler development at RR Software or PTC s= o that they support Ada2012 and Ada2020 by, say, 2023? =E2=96=AA=EF=B8=8E resurrection of effectively dormant source code bases a= t HPE or Tartan/DDC-I?
