Maybe it's high time someone address this shortcoming as opposed to adding
additional language front ends. If you can't even get the core ones right...
Just saying...

Generally the people who add front-ends aren't the people working on the
middle-end and optimisers, so work on one doesn't take resources away from the
other.
Feel free to pay someone to fix it if this is important to you. Just sayin'

Moreover, the people that add new FEs are not the same people working on the
C/C++ FEs.
Anyway, in the comments above you can find the reasons why this is difficult,
how Clang has solved it (or so they say, I haven't seen a comparison over many
different testcases), and why you should not expect a fix in the medium term.

It still adds work to the project as a whole and serves as a distraction for
new people who have the time to contribute.

If fixing known bugs is not a priority then of what value is this project other
than being free? I thought the whole point was to also be correct. Granted
this isn't a show-stopper as far as bugs go, but the laissez-faire "if you hate
it fix it yourself" trend in OSS is really annoying.
When I ran my own OSS projects I never told the users "nyah nyah fix it
yourself!" When I ran out of time to work on the OSS projects I gave them up,
but so long as I called myself a maintainer I addressed issues as best as I
could.
I'd almost rather they leave it as WONTFIX then just leaving it open. I'd also
be happier if they documented this class of SSA fail in the man page so people
don't walk into it [as I and others have].

The same could be said of any feature or bugfix. It depends on your priorities
and viewpoint. In fact, the way GCC development works, making a new feature
work (like a new FE) may provide the motivation for someone to fix an old bug.
> I'd almost rather they leave it as WONTFIX then just leaving it open.
How is that a solution? People will keep reporting it. As said above, it took
more than 8 years to solve some bugs, but someone came around and fixed them.
There are much older bugs than this one that may get fixed in the next couple
of releases.
WONTFIX means GCC devs don't want a fix. This is not the case here. There are
even ideas above about how to fix this. It is just that there is no enough
motivation for anyone to deal with the probably huge amount of work it
requires.

Not quite, and saying it that way, sends the wrong message. It's more like
"are not going to put resources (of their own) into fixing it".

So is the trend of users who leave snarky "just saying" comments claiming
things "can't be done right." GCC is not a static analysis tool, it will never
be as good at some things as some other tools - that doesn't make it useless or
incorrect. Imperfect, yes, and noone disputes that.
Fixing bugs is a priority, just look on the mailing lists to see how many are
fixed. Search for Manu's comments to see how hard he works (in his own time)
trying to fix longstanding bugs such as this, or at least try to improve the
situation slightly, or just identify duplicate reports.
But not all bugs are equal. To generalise from the fact that one particularly
difficult bug hasn't been fixed to claim that fixing known bugs is not a
priority, and to question the value of the entire project, just makes you sound
ridiculous.

BTW, anyone interested in fixing this may want to take a look at the newest
proposal for improving Wuninitialized in Clang:
http://lists.cs.uiuc.edu/pipermail/cfe-dev/2011-February/013170.html
They specifically mention the issues of GCC's implementation and how they plan
to address them. Nevertheless, there are several problems for implementing
Clang's approach in GCC. First, they prefer to have false positives (a false
warning) than false negatives (a missed correct warning), whereas GCC tries as
hard as possible to not warn when it shouldn't. Second, their proposal makes
use of the static analysis checker build into clang, which GCC does not have
(and probably never will) in its front-ends.

Richard, I would suggest to remove the regression markers. This is a regression
since 4.0 that it is unlikely to be fixed in the near future. Hence, not really
worth to track as a regression. One less bug to handle by the release managers.

BTW, Clang has decided to implement this in the FE for simple cases.
Quoting: http://clang.llvm.org/docs/ReleaseNotes.html
-Wuninitialized has been taught to recognise uninitialized uses which always
occur when an explicitly-written non-constant condition is either true or
false. For example:
int f(bool b) {
int n;
if (b)
n = 1;
return n;
}
sometimes-uninit.cpp:3:7: warning: variable 'n' is used uninitialized whenever
'if' condition is false [-Wsometimes-uninitialized]
if (b)
^
sometimes-uninit.cpp:5:10: note: uninitialized use occurs here
return n;
^
sometimes-uninit.cpp:3:3: note: remove the 'if' if its condition is always true
if (b)
^~~~~~
sometimes-uninit.cpp:2:8: note: initialize the variable 'n' to silence this
warning
int n;
^
= 0

Infamous PR18501. With:
~/test1/197214/build/gcc/cc1 -Wall -Wextra -O1 pr56972.c -fdump-tree-all-lineno
you can see that pr56972.c.020t.copyrename1 contains the uninit use but
pr56972.c.021t.ccp1 has removed it.

--- Comment #95 from Martin Sebor <msebor at gcc dot gnu.org> ---
Reconfirmed with GCC 11.
I wonder if running CCP first, just before the early uninit pass, but only to
propagate constants and without modifying the CFG, and then the "late"
uninitialized pass to look for uninitialized operands in the PHIs while
evaluating the predicates using the CCP lattice values, would be a way to get
back the warnings without introducing false positives.
