[PATCH 00/39] Use g_assert_not_reached instead of (g_)assert(0, false)

[PATCH 00/39] Use g_assert_not_reached instead of (g_)assert(0, false)

[Pierrick Bouvier]

This series cleans up all usages of assert/g_assert who are supposed to stop
execution of QEMU. We replace those by g_assert_not_reached().
It was suggested recently when cleaning codebase to build QEMU with gcc
and tsan: https://lore.kernel.org/qemu-devel/54bb02a6-1b12-460a-97f6-3f478ef766c6@linaro.org/.

In more, cleanup useless break after g_assert_not_reached();

And finally, ensure with scripts/checkpatch.pl that we don't reintroduce
(g_)assert(false) in the future.

A general suggestion for the entire series: please use a commit
message that explains why this is a good idea.  Even something as
boiler-plate as "refer to commit XXX for rationale" that can be
copy-pasted into all the other commits is better than nothing,
although a self-contained message is best.  Maybe:

This patch is part of a series that moves towards a consistent use of
g_assert_not_reached() rather than an ad hoc mix of different
assertion mechanisms.

Or summarize your cover letter:

Use of assert(false) can trip spurious control flow warnings from some
versions of gcc:
https://lore.kernel.org/qemu-devel/54bb02a6-1b12-460a-97f6-3f478ef766c6@linaro.org/
Solve that by unifying the code base on g_assert_not_reached()
instead.

If using g_assert_not_reached() instead of assert(false) silences
the warning about missing return value in such impossible to reach
locations should we also be deleting the now-unnecessary "return"
statements after g_assert_not_reached()?

Although it's unlikely to be used on any compiler that can also
compile qemu, there is a third implementation of g_assert_not_reached
that does nothing, see:

https://gitlab.gnome.org/GNOME/glib/-/blob/927683ebd94eb66c0d7868b77863f57ce9c5bc76/glib/gtestutils.h#L269

Interesting.
At least gcc, clang and msvc are covered, this should be ok for most of 
the builds.

Thanks for sharing,

All of that is inside #ifdef G_DISABLE_ASSERT, which we will never set.

That's only in the #ifdef G_DISABLE_ASSERT case ... and we forbid that in 
QEMU, see osdep.h:

#ifdef G_DISABLE_ASSERT
#error building with G_DISABLE_ASSERT is not supported
#endif

So in QEMU, g_assert_not_reached() should always abort.

The tail of this series remove the unreachable 'break' lines.
Why 'return' lines aren't problematic? Is that a GCC TSan bug?

It's related to how control flow analysis works, but I don't have a 
deeper answer. I reported the issue with 'break' for gcc and the same 
bug was created several years ago, so it was just marked as duplicate.

I'll clean the extra return with have though, as part of v2.

If break does not make sense after g_assert_not_reached() and removed then 
return is the same here.

It may make the series shorter and easier to check that none of these are 
missed if this is done in the same patch where the assert is changed 
instead of separate patches. It's unlikely that the assert change and 
removal of the following break or return would need to be reverted 
separately so it's a simple enough change to put in one patch in my 
opinion but I don't mink if it's kept separate either.

Mostly done this way because it's easy for creating many commits.

I'm queuing reviewed patches 4,5,7,10,27,28,30,36 so you don't
have to carry them in v2.
