GPL 2008 is out... and it's faster!

GPL 2008 is out... and it's faster!

[Alex R. Mosteo]

Hello,

I'm sure many of you are aware that the GPL 2008 version of GNAT was released
yesterday. It includes several goodies, but the first thing I noticed when
compiling part of my codebase is that it felt faster.

And sure enough, here is a preliminary test, compiling my particular do-it-all
library:

$ time gprbuild -Pagpl

GNAT GPL 2007
real    4m35.149s
user    4m1.219s
sys     0m12.529

GNAT GPL 2008
real    3m55.710s
user    3m22.225s
sys     0m12.713s

I guess there's been a change in the gcc backend leading to this nice speed-up.
Incidentally, I had to change just one line of code to get this (rather large)
library to compile (some ambiguity that wasn't perceived as such in the 2007
version).

And now, to test if interfaces are more useable than before...

Where did you download it from? from The Libre Site https://libre2.adacore.com/
I notice GNAT GPL Edition 2008 Coming Soon! sign a couple days ago. I
downloaded all previous releases of GNAT from here. However, GNAT GPL
2008 is not available yet.

It is nice to know that GNAT has evolved and improved. Thanks to
AdaCore for providing this great service to Ada Community.

Ah, uhm. I got it via the GAP program. I assumed that, since GAP and GPL are
now synchronized, it would be the same thing. I guess it will be generally
available at any moment.

As of this writing, GNAT GPL 2008 is not available yet. I hope it will
be out in next day or two.
