I build llvm and clang cross compile environment, but test has error：
USE follow command:
clang -O0 -emit-llvm -target or1k-linux filename.c -S -o filename.ll --sysroot /opt/or1k-tool-chain/or32-linux/ -I /opt/or1k-tool-chain/or32-linux/include/
clang hello.ll -target or1k-linux -c -o hello.o
##############but I can't generate ELF FIles
clang hello.o -target or1k -o hello

hello.o: could not read symbols: File in wrong format
collect2: error: ld returned 1 exit status
