PS: GCC 4.0 will be in the long waited Mac OS X v10.4 (Tiger)

So? Do you want this for MOS? Forget it.

We will probably never get past 2.95.

3.x is "too buggy", People-from-MOS-Team says.

MOS-team seems half-dead... who worries about them?

Yawn...

I want GCC4 for MorphOS, and Portage on MorphOS
Dreaming is for free ;-P

@Hawk

Yes, that can be very interesting, a lot of programs will can be ported to MorphOS and easier...

@ironfist

People can port it themselves. You dont need explicit permission from the MorphOS team.

@itix

Too complex for one single person. Normally people not join for do things, not know how doing things in group. It's nearly impossible that one guy can port all the GCC 4 stuff, no?

@timofonic

So instead of coding MorphOS the team should be porting GCC 3.x? No doubt GCC3 is urgently needed for MorphOS but there are also priorities.

GCC 2.x or 3.x was never ported to Amiga by Commodore but community approved the port anyway. Why should this be different with MorphOS? It is not terribly wrong if someone outside of the MorphOS team ports GCC 3.x.

@itix

Why GCC 3.x? Better GCC 4.x...

I consider in some things the latest GCC more important than MorphOS 1.5, because we can live temporary without MorphOS 1.5 but we need more software...

I don't think you'll get more (or less) software if you use Gcc 3.x or
even 4.x. Most of stuff compiles just fine with the 2.95.3.
Some people even use VBCC (which may miss some gcc extensions).

Code genrated by Gcc 4.x may be smarter, but may also contains several
mistakes. Look at Gcc 3.x, it prolly reached a usable state by now,
but it was a pure catastrophe at the beginning.

Your sincerly,

I think you'll find Apple has their own custom branch of gcc.

Because of gcc was not the "official" CBM/Amiga compiler, while it is for MorphOS.

alfie

@timofonic:

so, when did u say u are gonna start porting it? ;P

Animo!

@Hawk

Never, let MorphOS team release their official port

GCC 4.0.0 released:

More interesting improvements:
- SSA for trees, allowing for a completely new optimization framework that allows to design optimizations in a easier manner.
- Autovectorization, allowing vectorize parts of the code which are converted to SIMD code(MMX, 3Dnow, SSE, altivec, etc) and in some curls they obtain very good gains of yields.

Here are the results of compiling nbench with different options from optimization, GCC 3.4.3 and GCC 4.0alpha, and also a test with the FSB (slightly) overclocked
