You should take GCC and Binutils separate components here.

You can take it this way, GCC mostly take charge of generating asm while
Binutils mostly take charge of transforming asm to bytecode.

For LLVM, their asm generate and bytecode transform are in the same
codebase, and they might could pass them.
