Here are the changes, and you can see a list of ftp servers here. This is the release I have been waiting for. I will now upgrade :-) Well Done to all involved!"

  1. Most Notable Improvements by Sentry21 · · Score: 4, Informative

    Here's a short run-down of the improvements that really caught my eye this time around.

    • Better PPC support (64-bit PowerPC GNU/Linux support in the backend, and altivec support with -maltivec)
    • UltraSPARC 64 fully supported
    • AMD x86-64 support
    • SSE/SSE2/3DNow!/MMX instructions and command-line flags to enable. No C++ compatible intrics for SSE2
    • New ports for MMIX, CRIS, and SuperH
    • Code profiling

    Everyone knows I'm no fan of the GNU project, but GCC3.1 shows that they have a lot going for them. Very exciting guys, I can't wait to see what 3.2 has in store.

  2. Re:Does it compile KDE? by Anonymous Coward · · Score: 2, Informative

    Yes, some of the KDE developers are already using GCC 3.1. It compiles and runs KDE without problems.

    Are you running on x86 or SPARC?
    I've built various versions of gcc-3.0.x and 3.1-xxxxx on SPARC and intel multiprocessor boxen on Solaris 8 and 9.
    What C compiler are you using to start the bootstrap build?

    I have the Freeware Companion CD installed, so am using gcc-2.95.3.

    Here is my configure line:

    ../gcc-3.1/configure --prefix=/area51/trial/install/gcc-3.1 --with-ld=/usr/ccs/bin/ld --with-as=/usr/ccs/bin/as --without-gnu-ld --without-gnu-as --enable-shared

  4. Re:Most Notable Improvements - export? by jdennett · · Score: 3, Informative

    Nope, the only compilers which are close to having export are the EDG-based ones. Comeau might be on sale in release (rather than beta) form this month. No released compiler has export just yet, but some are real close now. (http://www.edg.com/ or http://www.comeaucomputing.com/ for some more details if you care.)

    In short: thing that reduces bloat/speed/compile time when you use templates. Every bigger c++ (KDE and the like) project would kill for it. But AFAIK it is difficult to implement... pitty.

    ODR is One Definition Rule. It's the clause of the ISO C++ Standard (that's where you'd go to look for it) that says that an entity used in a program must be defined exactly once.

    Some of the KDE libs apparently were trying to define things more than once, and have the linker merge them. Which falls outside the realm of C++, and is actually done for some behind-the-scenes things, but not normally, and not by default.

    Anyhow, there was a long thread on the gcc list, where the remaining multiple inheritence issues were dealt with, and the ODR problems explained to the good KDE folks. So all should be well there.

    Slow startup times remain; that's a different problem.
