Assuming the same optimizer complexity, it might be true, because Ada
provides more and more precise information to the compiler than C.

This design goal is well known: Such software can be easily identified.

This is a complete other term: Development time. Ada allows much better
reusability than C. And Ada programms are much faster debugged than C
programms. (Assuming equaly experienced programmers)

Linus tried to convert the kernel to C++ in order to get faster development
cycles due to stronger typing but failed miserably due to compiler errors
and language ambiguity.
