Relevant binutils commit: https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=60a3da00bd5407f07 I first fixed this without introducing the compat header, as suggested by Quentin, but I thought the amount of repeated boilerplate was a bit too much. So instead I introduced a compat header to wrap the API changes. Even tools/bpf/bpftool/jit_disasm.c, which needs its own callbacks for json, imo looks nicer this way. I'm not regular contributor, so it very well might be my procedures are a bit off... I am not sure I added the right [number of] people to CC? WRT the feature test: Not sure what the point of the -DPACKAGE='"perf"' is, nor why tools/perf/Makefile.config sets some LDFLAGS/CFLAGS that are also in feature/Makefile and why -ldl isn't needed in the other places. But... V2: - split patches further, so that tools/bpf and tools/perf part are entirely separate - included a bit more information about tests I did in commit messages - add a maybe_unused to fprintf_json_styled's style argument V3: - don't include dis-asm-compat.h when building without libbfd (Ben Hutchings) - don't include compiler.h in dis-asm-compat.h, use (void) casts instead, to avoid compiler.h include due to potential licensing conflict - dual-license dis-asm-compat.h, for better compatibility with the rest of bpftool's code (suggested by Quentin Monnet) - don't display feature-disassembler-init-styled test (suggested by Jiri Olsa) - don't display feature-disassembler-four-args test, I split this for the different subsystems, but maybe that's overkill?
