I believe that llc only accepts LLVM bytecode, while llvmg++ only 
generates LLVM assembly code (i.e. human readable LLVM code that must be 
assembled with llvm-as or gccas).

If the above command line does not work, please try the following:

llvmg++ -c infile.cpp -o - | llvm-as | llc -march=c -o infile.cbe.c
