However, a compiler built this way does provide a C backend, which may be
useful for creating system packages of Zig projects using the system C
toolchain. **In this case, LLVM is not needed!**
Furthermore, a compiler built this way provides an LLVM backend that produces
bitcode files, which may be compiled into object files via a system Clang
Even when built this way, Zig provides an LLVM backend that produces bitcode
files, which may be optimized and compiled into object files via a system Clang
package. This can be used to produce system packages of Zig applications
without the Zig package dependency on LLVM.
