[PATCH v2 0/5] tools: fix compilation failure caused by init_disassemble_info API changes
Posted by Andres Freund 3 years, 9 months ago
binutils changed the signature of init_disassemble_info(), which now causes
compilation failures for tools/{perf,bpf} on e.g. debian unstable. 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

The Debian kernel-team has integrated your patchset v2.

In case you build without libbfd support there is [1].
So, feel free to take this for v3.

Thanks, I meant to send that fix upstream but got distracted.  It
should really be folded into "tools perf: Fix compilation error with
new binutils".

Always try to do things in chronological order;

I'll try to send a new version out soon. I think the right process is to add
Signed-off-by: Ben Hutchings <benh@debian.org>
to the patch I squash it with?

Sorry - had hoped to finish sending it out before my vacation (and then on the
flight, but wifi didn't work...). Now back, will work on it asap.

Ok, so you agreed on this, I'm adding Ben's Signed-off-by tag then,

HI,

what was the base for this patchset?
I tried with Linux v5.19-rc5 and it doesn not apply cleanly.

I think the disassembler checks should not be displayed by default,
with your change I can see all the time:

...        disassembler-four-args: [ on  ]
...      disassembler-init-styled: [ OFF ]


could you please squash something like below in? moving disassembler
checks out of sight and do manual detection

thanks,
jirka

Makes sense - I was wondering why disassembler-four-args is displayed, but
though it better to mirror the existing behaviour. Does "hiding"
disassembler-four-args need to be its own set of commits?

This I don't understand - why do we want these to run under NO_LIBBFD etc?

I guess first hide the disassembler-four-args and add the new the same way

when I was quickly testing that I did not have any of them detected
and got compile fail.. so I moved it to safe place ;-) it might be
placed in smarter place

I think that's because you'd removed them from FEATURE_TESTS_BASIC in
Makefile.feature. In v3 I just sent out I just removed them from
FEATURE_DISPLAY, without any more "structural" changes in
tools/perf/Makefile.config.
