--- Comment #3 from Martin Liška <marxin at gcc dot gnu.org> ---
Well, I doubt the warning is much useful.
There are situations where we can't use short-circuit evaluation:
gcc/c-family/c-attribs.cc:2384:
else if (TREE_CODE (decl) == FUNCTION_DECL
&& (((curalign = DECL_ALIGN (decl)) > bitalign)
| ((lastalign = DECL_ALIGN (last_decl)) > bitalign)))
or we want to quickly and flags of a struct:
gcc_checking_assert (!IDENTIFIER_KIND_BIT_2 (id)
& !IDENTIFIER_KIND_BIT_1 (id)
& !IDENTIFIER_KIND_BIT_0 (id));
Note a different code is generated for situations like:
return foo() && bar() && baz ();
and
return foo() & bar() & baz ();
So I don't think we should change the code based on the warnings.
