Waiting for 3.2.1

Well, according to this, you should only have to wait until Sept 15.

sure, but well...It'll take until 3.3.x before everybody drops 2.95.x...

But I am looking forward to 3.2.x because I believe it is generating useful code ;-)

eh actually 3.3 which was 3.2 isnt that radical in terms of 'stupid things we had to do over to get things to work cuz they were really really broken in the first place' kind of things ... But now for 3.4, they are rewritting the parser _again_ and mucking with the intermediate rtl I believe (Mark Mitchell and CodeSourcery)... that of course will mean more regressions than 3.0 had with 2.95 and then some ....

Of course, if it works out, the compilation speed should be vastly better, the optimization people will find it easier to use the new rtl for advanced forms of block optimizations and prefectching, the binary sizes may fall again

AND that _lil_ problem where gcc eats all 3 of your swap drives compiling inline functions the proper way (a sane and intelligent way) will hopefully be gone.

because of this im just hoping that we dont have to wait for 3.5 before it's finally back on track with the reputation gcc has had in the past. But other than that rewrite and the other necessary stuff that has to get added yes 3.3 and 3.4 should both be fairly good.

However, if you are watching the nightly/weekly/sometimes monthly runs of Spec95 and Spec2000 and the Bench++ benchmarks being run on gcc.gnu.org, I cringe every time where I see 2.95.3 _still_ beating the crap outa 3.x and the ICC spec runs put gcc to shame on the runtime marks.

I could see that as a call to a class constructor maybe, but most people do casts via

Yeah, thats a _normal_ ''stupid thing we had to do over to get things to work cuz they were really really broken in the first place" thing. There's usually quite a bit of those. Not nearly as 'radical' as a parser rewrite though.

Examples of major changes include:

A new C++ parser
A new memory allocation scheme for internal use in the compiler
A new optimization pass

Hmmm, I believe there was a parsing problem similar to this on the gcc mailing list a few days back .... http://gcc.gnu.org/ml/gcc/2002-07/msg01033.html

Is your problem known?
