My bad. I am running 10.6.8 which seems to be still based on gcc. Is the parser for the compiler on current Mac OS X now LLVM's code or gcc's front end?

As all Apple software is based on gcc, a personal protest by you against Apple's practices would probably be quite effective - how come you aren't doing something?  This thread started with worries about restrictive Xcode licenses, which essentially translates for us to restrictive gcc licenses.


"As all Apple software is based on gcc" - where did you take that info from ?

LLVM is an _open_ source and _free_ (in FSF sense of the word) software, and for more than two years it has been self-hosting: :

Self-sufficiency is a major milestone for any compiler technology.  The LLVM (Low Level Virtual Machine) developers were pleased to announce that their open source compiler, named Clang, has just reached this milestone.  Clang recently completed its first complete self-host by building all of the LLVM and itself.

In the testing process, Clang was able to compile over 550,000 lines of C++ code, which is the total amount of lines in LLVM and Clang.  The resulting binaries passed all of the regression test suites for Clang and LLVM.  The self-built Clang was then able to build the 550k lines LLVM and Clang code again.  The third Clang build was also fully-functional, which made the bootstrap complete.

Furthermore there are Linux distros are partially based on LLVM already: :

openSUSE 12.1 also comes with the just-released LLVM3 compiler tool and clang, the C/C++ compiler building upon LLVM. LLVM is employed by the open source ATI and NVIDIA accelerated graphics drivers and thus forms an integral part of a high-performance graphics stack on Linux.
