The Green Hills Ada95 compiler was the first, and, to my knowledge, only,
compiler
to have completed ACVC 2.1 validations.  This validation included the
Systems
Programming Annex as well as the Real-Time Systems Annex.  The Green Hills
Ada95 compiler is a very mature implementation of Ada95.

I am a senior compiler developer at Green Hills Software.  Neither issue
that Joe Gwinn
ran into is a result of what Kevin refers to as the "reusing" or having
"glued" the Green
Hills "C code generator with the Intermetrics Ada95 front-end".  

The current 68K cross compiler implementation of exception handling in the
current
fashion has almost nothing to do with the code generator.  Rather, it is an
issue for the 
linker, Ada runtime system and, in some cases, the commercial target
operating 
system.  Another oversight by Kevin is the fact that the Green Hills
backend 
design is not limited to the C language.  Green Hills' backends/code
generators are 
designed to support Ada95, C, C++, Fortran and Pascal.  With this breadth
of 
language technology, there is nothing that hasn't been done or can't be
done with 
the Green Hills backends to fully support a highly optimizing Ada95
compiler.  As 
Tucker mentioned, we are currently developing a table-driven exception
handling 
scheme.

Like OC Systems, Green Hills is without question, sensitive to our
customers
concerns and needs.  Our primary goal is the success of our customer's
programs
and products.  To that end, we are always flexible and open to any
suggestions from
customers regarding the improvement of our Ada95 compilers and the
supporting 
software development tools.
