I was s= earching as I was planning to build a subset of Ada 2012 (in Ada 2012 using= GNAT).

The work there has been in a sub-project called Do you have a website with the course materials at all? Always worth a look= . Why don't you set up your compiler as a means for students to add to, i.e= . add floating point support, add real-time annex, etc. That would get your= compiler off the ground faster and might even take less than 6 years to co= mplete. > Allegra which is intended to be a compiler for a series of highly You might want to change the name as there is a project with that name alre= ady, see #Ada on Freenode. > reduced Ada subsets with increasing complexity.
