Ada for bare target-A conceptual question

[harbaughs@EGLIN-VAX.ARPA ("Samuel S. Harbaugh")]

Q1. Is it intended that I can write every line of code for a
target computer in Ada?
Q2. Is it intended that the compiler etc. on my host machine be
able to compile, link that Ada code so that I can load}{
it into my target machine?
Q3. Will (does) the ACVC check that this can be done.
--
Commentary- I want the answers to the above to be yes but I need
to understand the situation. I recall in 'the early days' the
challenge of writing a keyin loader in the minimal
number of instructions(7 I recall on the machine I was using)
so I will accept 7 hand-compiled machine instructions to
boot my loader (written in Ada) which will load my program
(written in Ada) which will completely control the stae of the
hardware ( control and service interrupts, handle disc
I/O etc.).
     If I am expecting more than Ada is required to deliver
please tell me because I need to have this staright in my mind.
Thanks in advance.
regards, sam harbaugh
