[LLVMdev] Compilation error while cross compiling LLVM for ARM - the __clear_cache issue - now the __sync_val_compare_and_swap issue - now the internal compiler error issue.

[Prasanth J]

Hi,

I can able to compile LLVM using armgcc_4.3.3 (codesourcery2009q1..).. but
when i tried to run it on target it shows GCC 4.3.0 version not found. So i
copied the runtime libraries (libc.so and libgcc_s.so) from the toolchain to
the target and exported its path in LD_LIBRARY_PATH. But when i tried to run
any llvm tools on target its crashing with Segmentation fault. What could be
the problem for this.

My target kernel and rootfs are compiled with armgcc-4.2.1... so should i
need to compile the kernel and rootfs with armgcc-4.3.3?

If i want to use arm-toolchain-4.2.1 , what should i do for clearing the
instruction cache call in lib/System/Memory.cpp?

Thanks and Regards,
Prasanth J
