GPL 2008 is out... and it's faster!This is a discussion on GPL 2008 is out... and it's faster! within the ADA forums in Programming Languages category; 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...  |

It includes several goodies, but the first thing I noticed when 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. > 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... It is nice to know that GNAT has evolved and improved. Thanks to AdaCore for providing this great service to Ada Community. AV |

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. > >> 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.

I hope it will be out in next day or two. AV |
