llvm/lib/System/Atomic.cpp contains the call to __sync_val_compare_and_swap that lowers to the missing __sync_val_compare_and_swap_4 GCC intrinsic. The same file contains several other __sync_* calls and all these has to be implemented if we want to be able to compile llvm on linux/ARM with GCC versions below < 4.4 xerxes at labbserver:~/llvm$ grep _sync lib/*/* lib/System/Atomic.cpp: __sync_synchronize(); lib/System/At...

Hi, i am a newbie to llvm architecture. i have been trying to port llvm on ARM target. i am using the following configuration for cross compiling llvm. ../llvm/configure --host=arm-linux --target=arm-linux --build=i686-linux --prefix=/opt/llvm-arm/ --enable-optimized --disable-debug \ --disable-expensive-checks --disable-doxygen \ --disable-threads --enable-targets=cbe,cpp,arm using this
