The warning is useful and can find (and already found) several real bugs e.g.
in gcc itself. Icc has similar warning.
If kernel has lots of useless code like that and doesn't wish to use this
warning, it can add -Wno
--- Comment #4 from jakub at gcc dot gnu dot org 2010-06-09 10:52 ---
We don't warn on
void foo (void)
{
int dummy;
asm ( : =r (dummy));
}
- the use in the asm is considered as a use, not just set.

--- Comment #6 from jakub at gcc dot gnu dot org 2010-06-09 11:36 ---
Then it has nothing to do with the asm.
If the macro is widely used and very often sets a var that isn't used, all
you can do is add (void) cast to shut the warning up.
(void) (y = var 16);
in this case.

I guess for empty bbs with no successor where the predecessor ends in an
conditional jump without side-effects try_optimize_cfg can't do just
delete_basic_block, but needs to call some function to actually adjust
--- Comment #3 from jakub at gcc dot gnu dot org 2010-06-09 13:55 ---
There are more issues:
1) cleanup_barriers seems to do weird things with these empty bbs from
__builtin_unreachable (), I guess it shouldn't reorder anything if prev is a
LABEL_P
2) the reason why this compiles fine

That's correct, it shouldn't compile.
The OpenMP standard doesn't allow != comparisons in omp for condition, only ,

All the tests demonstrate is that you have buggy constraint, in particular
you shouldn't use g constraint on something you use in gs:[%2].
g is any register (fine in that case), immediate (not fine) or memory

You are wrong. It is user's responsibility to choose correct constraints for
the inline assembly, the compiler doesn't try to understand what the inline
assembly is doing or even check its semantics, all it does

redhat/gcc-4_4-branch doesn't have a -fcompare-debug failure here, though, I
see now that S::f3 doesn't end a basic block before inlining either, just
inlining happens in a different order.

Not 100% sure yet, but I believe this commit broke bootstrap on both
x86_64-linux and i686-linux, e.g. in libobjc or in ada bits.
One of the ICEs I'm seeing is:

Can you explain the struct __emutls_object change? That is an ABI break (and I
don't see anywhere any rationale for that).

Not sure whether this patch is still needed now that var-tracking already
delegitimizes MEMs (and their addresses) too.
That said, if you have a testcase where this is still needed, the patch looks
reasonable, so you

extern char a[], *b[];

foo (char *x, int y)
{
x = __builtin_stpcpy (x, b[a[y]]);

GCC has -fkeep-inline-functions, perhaps that's what you are looking for.
That said, I still don't understand why you need something like that.
