Is it available > somewhere to look at? yes. you can use verifier instruction format. That was the goal for llvm to be as close as possible to kernel verifier syntax. But, I think, it's fine to deviate if it makes asm code easier to read. What is missing is AsmParser directory in llvm/lib/Target/BPF disassembler, elf tools, codegen are all there. Most of the core backend components are shared in the llvm, so it's only missing text parser. Most backends already have assemblers: ls -d lib/Target/*/AsmParser To make one for BPF requires a lot of copy-paste from others ;)
