No.  The Ada reference manual and the validation suite are the same
for all compilers and systems.

What is what you thought?

I'm afraid I have no idea what you mean by "extended instruction set".
Certainly Ada compilers for the VAX can provide
implementation-specific pragmas and attributes, this is allowed by the
standard.  They also provide machine-code insertions (which aren't
expected to be portable) and additional library packages (which are
implemented *in* Ada; they aren't extensions to the language itself).
None of this makes it particularly difficult to write portable code
that will work properly on a VAX or anywhere else.

Can you provide an example of what you're talking about?
