In recent weeks I've been developing an eBPF assembler, implemented in Python. It can be found at https://github.com/solarflarecom/ebpf_asm and it consumes an Intel-like syntax very different to that consumed by LLVM or emitted by the kernel verifier's disassembler. To quote from the 'Rationale' section of the readme: > It's great that you can write eBPF programs in C and then compile them with clang/LLVM. But clang's really rather big, and sometimes you don't have room for a gigantic toolchain — and your program is really small and simple. For such a case, writing the program directly in assembly is a feasible alternative. > > I chose the Intel syntax because my ability to read assembly code is directly proportional to how much it resembles Z80. If you dislike that as much as I dislike AT&T-syntax x86 assembly, this may not be the tool for you. > My personal use case for this was developing directed tests for a driver XDP implementation. There may be others. -Ed
