I've just had a quick look at the code.

While I understand your focus on setting up the Ada vector routines in the
vector table, I wonder if it would be wise to also look at the requirement
to store the value (at 16#00000000#) to be used for the initial stack
pointer in case that shows up any additional issues with elaboration (or
anything else).

One obvious model would be to have a record with a initial 32 bit address
variable followed by a array of Cb as you have now.

The interesting question however, is how are you going to populate that
stack pointer variable ? Are you planning to use a hardcoded constant
within the Ada code or are you planning to define a symbol within the
linker script and import that into the Ada code ?

If it's the latter, I wonder if the compiler will generate any additional
unexpected elaboration code or if the generated code will just reference
the linker symbol directly ?

Simon.
