Hi, Im trying to generate C source from C++ source file, using C backend. llvm-g++ -O3 -emit-llvm valen.cpp -c -o valen.bc llc -march=c valen.bc -f -o valen.c But C backend generate a lot of operation with "long long" type. My C compiler does not support "long long" type. Is there any option to disable generate "long long" ? -- Thanks, Valen
