Subject: init_disassemble_info() signature changes causes compile failures

Hi,
binutils changed the signature of init_disassemble_info(), which now causes
perf and bpftool to fail to compile (e.g. on debian unstable).
Relevant binutils commit: https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=60a3da00bd5407f07d64dff82a4dae98230dfaac
util/annotate.c: In function ‘symbol__disassemble_bpf’:
util/annotate.c:1765:9: error: too few arguments to function ‘init_disassemble_info’
1765 | init_disassemble_info(&info, s,
| ^~~~~~~~~~~~~~~~~~~~~
In file included from util/annotate.c:1718:
/usr/include/dis-asm.h:472:13: note: declared here
472 | extern void init_disassemble_info (struct disassemble_info *dinfo, void *stream,
| ^~~~~~~~~~~~~~~~~~~~~
with equivalent failures in
tools/bpf/bpf_jit_disasm.c
tools/bpf/bpftool/jit_disasm.c
The fix is easy enough, add a wrapper around fprintf() that conforms to the
new signature.
However I assume the necessary feature test and wrapper should only be added
once? I don't know the kernel stuff well enough to choose the right structure
here.
Attached is my local fix for perf. Obviously would need work to be a real
solution.
Greetings,
Andres Freund
