April 2002 Dev Tools Include gcc Update

Posted by pudge on from the look-ma-i-can-build-me-some-softwarez dept.

snyperm writes "stepwise.com indicates that the April 2002 Developer Tools have been seeded to developers and is scheduled for release sometime in the coming weeks. The improvement of gcc 3.1 alone is noteworthy as arstechnica indicates there should be somewhat substantial increases in speed ahead for Mac OS X. One step closer to 10.2!" Also included, according to the story, is a ProjectBuilder 2.0 beta.

    GCC3.1 still doesn't have altivech optimization, which is what is really needed at this point for a speed boost for OSX apps. Good to see the update coming, though.

  3. OS X / GCC by mkoz · · Score: 3, Interesting

    Does anyone know what it takes to become a primary or secondary evaluation platform? It would seem to me that it would be worth Apple's while to front the money / people to make OS X a primary or secondary evaluation platform...

  4. Altivec? by Lally+Singh · · Score: 3, Funny
    Odd, from the release notes:
    GCC 3 has greatly improved code optimization, especially for Altivec code.
    -faltivec Optimizes code for the Altivec.

    Not that this release is going to be some automatically vectorizing compiler... Previous experience tells us how really hard that is. But, we can expect some basic altivec usage.

  5. GCC changes by Lally+Singh · · Score: 3, Informative
    These notes describe a pre-release of GCC 3, based on the GCC compiler version 3.1 for C, C++, Objective-C, and Objective-C++. GCC 3 is the biggest change for GCC in ten years and represents two years of development. It offers the following benefits over GCC 2, the compiler that shipped with the Mac OS X 10.1 Development Tools:
    • Faster compilation times due to new precompiled header mechanism. Now C++ code can take advantage of precompiled headers as well. See Precompiled Headers.
    • Better code optimization and generation. If you avoided turning on optimization in the past, now would be a good time to try it again. See Optimization.
    • Better C++ support. In addition to supporting precompiled headers for C++, GCC 3 contains the following improvements:
      • A stabler and more efficient application binary interface (ABI).
      • A new C++ standard library, including better support for the Standard Template Library.
      • Better compliance with the ISO C99 and ISO ANSI C++ specifications. Note that the new ABI means you need to recompile all your C++ libraries and frameworks.
    This would be karma whoring if I wasn't capped out...

  6. Actually, it does. by DeadMeat+(TM) · · Score: 4, Interesting
    From http://gcc.gnu.org/gcc-3.1/changes.html:
    Altivec support has been added for the PowerPC variants that support it. See -maltivec.
