Sorry, but I don't see anything in the concept of high-integrity
software that would make it a norm. High-integrity software is a set of
quality objectives, whereas infinite loops are (or aren't) part of
system requirements. These should stay independent, even though I
understand that expectations for both often come in pairs.
OK, just nit-picking. ;-)
I wanted to be sure that I understand it correctly, thanks.
Still, it looks like I cannot say:
pragma Profile(Ravenscar);
in my Hello World program even though this program meets the objectives
of the profile. That's not fair! :-)
