OK. Thanks for your help. My problem is I am playing with the size of registerfile in ARM. I thought I can do it with only modifying the Target in the LLVM directory. But if it is going to use gcc-toolchain, then I need to modify them as well which is a huge work! Best Regards, A. Yazdanbakhsh >>>>>>>>>>>>>>>>>>>>>...

That sort of depends how you modify it. If you just want to look at assembly output by clang then probably nothing...

Ok, These are the three options you should be playing with: -ccc-host-triple $(CCC_HOST_TRIPLE_ARM) \ --sysroot=$(SYSROOT_ARM) \ -gcc-toolchain $(GCC_TOOLCHAIN) Where the (sic) host triple defines the "target" triple too. Sysroot and gcc-toolchain is where you'll find the libraries and binutils for the ARM targets (you'll need them, since LLVM still can't cross-compile on

Thanks for your help. But I got this warning which it seems it doesn't use -triple "clang: warning: argument unused during compilation: '-triple arm-none-eabi' " Best Regards, A. Yazdanbakhsh >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> PhD. Student School of
