Re: WinNT ADA compilers comparison

[Nicolas Brunot <n.brunot@cadwin.com>]

From the user point of view, I think that reliability comes first (without
it, you usually lose so much time that generated code performance is useless
and means nothing)
More than that, increase performance by 5 doesn't mean a lot.
After a user action :
he will find not acceptable the difference between 1s and 5s
he will not care or even notice the difference between 1ms and 5ms
(And I saw some developpers spending days for the second improvement, while
not even care about the first ..., usually the user is not very happy)

Even if this is the most important, that doesn't mean you don't have to care
about development cost (one of the original purpose of ADA language, with
reliability)
As far as we are concerned, our code is far from being compile and linked
just once !
During the development process, corrections, maintenance,..., and before the
software can be provided to a customer, the code is compiled and linked
thousands of times.
I know few developpers linking just once a day.

For us, the difference between 20s and 4mns for linking is more than
important (we actually saw that difference between some compilers for same
code and executable)
