有谁对LLVM了解多点的？介绍下

据说freeBSD要换掉GNU编译器族为默认的编译器了 ，

观望阶段。

基本系统已经全部可以用clang编译，相信不久就会换了。

但是ports部分就遥遥无期了，尤其是涉及到C++的.

llvm 2.7 Release了,clang已经支持C++了
估计FB 9里面会加进来吧

Clang replacing GCC in the base system

   Since the last status report we got to the state where we are able to
   build all of FreeBSD (the C and C++ bits) on i386/amd64 with clang. The
   only exception is the bootloader which does not fit within the given
   size constraint. This is where the current efforts are going on. The
   C++ part got a big boost now being able to compile all C++ code in
   FreeBSD and itself.

   We saw some movment on Mips and PowerPC. Mips got its driver
   definitions from Oleksander Tymoshenko and Nathan Whitehorn did the
   same for PowerPC and tested the kernel. Currently, the PPC kernel seems
   to boot but due to lack of va_arg implementation for PowerPC nothing is
   printed out. Nathan is working on that.

   Overall ClangBSD is selfhosting on i386/amd64 and some progress has
   been made on PowerPC/PPC. We also saw some contribution to the Sparc64
   but this seems to have stalled.

   We need people to try out ClangBSD (see the wiki) and runtime test it.
   We also would appreciate help with other archs - namely ARM.

Open tasks:

    1. Runtime test ClangBSD on amd64/i386.
    2. Help with ARM/Mips/Sparc64.
    3. More testing of clang on 3rd party apps (ports).
    4. Discussion on integrating LLVM/clang into FreeBSD.

前两天2.7才Release的

xooass

性能会好点？

不知道～
关键是不知道以后内核会不会也全部转为这个编译，而不用GNU的了。
感觉怪怪的～

GCC许可换成GPLv3,之前都是v2的.所以BSD系列的操作系统都换编译器了
