Although previous patch allows setting BPF compiler related options in perfconfig, on some ad-hoc situation it still requires passing options through cmdline. This patch introduces 4 options to 'perf record' for this propose: --clang-path, --clang-opt, --llc-path and --llc-opt.
looks good. I hope only --clang will be used from time to time. Today, indeed, --llc* are needed too. btw, our experimental libbpfprog.so (which is clang and llvm libs compiled into single .so with C api for compiling .c into bpf): $ ls -lh libbpfprog.so -rw-r--r-- 1 ast ast 31M Jun 9 16:49 libbpfprog.so not tiny, but I think we should be able to include it into perf, then perf will only have build dependencies on llvm instead of run-time dependencies. We'll release this lib as soon as it's a bit more stable. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
