There might be more.

trace_events.h makes a whole bunch of functions `static inline` while they really should be just `inline`. (see discussion on https://chromium-review.googlesource.com/c/295484/ and some of the changes in  bug 315884 )

ssid, does making all the free functions in trace_events.h inline without static sound ok to you?

Comment 2 by thakis@chromium.org, Apr 11 2017

Summary: clang tot broken with -Wunused-function warnings, probably after clang r299930 (was: mac clang tot broken, probably after clang r r299930)
Linux too: https://luci-logdog.appspot.com/v/?s=chromium%2Fbb%2Fchromium.fyi%2FClangToTLinux__dbg_%2F5878%2F%2B%2Frecipes%2Fsteps%2Fcompile%2F0%2Fstdout

Comment 3 by thakis@chromium.org, Apr 11 2017

Windows has a separate error too:

         ^
1 error generated.

Maybe it makes sense to ask upstream to put this behind -Wunused-template-function or something like that, so we can clean it up async. (I'd try building locally and see just how often this fires now with -Werror removed, and if it's a lot then putting this behind a separate flag will be useful for others too eventually. If it's just 3 files, might as well fix.)

I'll stop looking at this now, sorry :-)

Comment 4 by h...@chromium.org, Apr 11 2017

Status: WontFix (was: Untriaged)
The warning was reverted in r299956 as it fired all over libc++

I'll attach my build log to see where this is firing, but marking this closed for now.

Comment 6 by thakis@chromium.org, Apr 11 2017

Looking forward to the attachment :-) If it fires a lot, we should still suggest a separate warning flag, ideally before it relands.

Comment 7 by h...@chromium.org, Apr 11 2017

Yup, I did suggest that.

These are the instances I saw on a full release build on Linux:

The ones in .cc files are likely to be dead code. I'll take a shot at removing some of it.

Comment 9 by ssid@chromium.org, Apr 11 2017

Is this still an issue?
Re #1: I think it's fine to replace static inline functions with inline. Also, it'd think we can remove functions/macros if they are really unused.
The error message is on AddMetadataEvent, which is not inline. I don't think we should make that inline, increasing code size (issue 702718).
