These 2 patch introduce a new perfconfig option (llvm.dump-obj) and a new cmdline option (perf record --dry-run). Combined together, perf user is able to generate a BPF object for an embedded platform on a x86 server using perf, instead directly using llvm cmdline and provide -I options and default macros.
