[Bug c++/24996] [4.0/4.1/4.2 Regression] ICE on throw code
--- Comment #12 from mmitchel at gcc dot gnu dot org 2006-01-23 05:10
---
I don't fully understand stabilize_expr; that's Jason's invention, IIRC.
However, I think that the problem is that for a COND_EXPR we can't pre-evaluate
both arms of the conditional, because only one of them is supposed to be
executed at runtime.
I think this is a bug in the gimplifier. I certainly don't see anything in the
documentation for CLEANUP_EXPR that suggests the restriction you've described.
I suppose that we could try to turn:
b ? T(x) : T(y)
into:
SAVE_EXPR b,
TARGET_EXPR (tmp, b ? T(&tmp, x) : T(&tmp, y), b ? cleanup1 : cleanup2)
but that seems difficult, and I'm not sure it would work.
By the way, here's a simpler test case:
struct A {
A();
~A();
};
struct S {
S(const A&);
~S();
};
void foo(bool b)
{
throw b ? S(A()) : throw 0;
}

This kind of template tends to be common place for certain catgories

I don't know which way to go yet, but certainly it should be

[Bug c++/24996] [4.0/4.1/4.2 Regression] ICE on throw code
--- Comment #11 from rakdver at gcc dot gnu dot org 2006-01-22 21:49
---
This ICE works this way: to build_throw, we get expression exp that looks like
TARGET_EXPR
Where t1 and t2 are TARGET_EXPRs with cleanups (*). build_throw generates code
TARGET_EXPR ;
try
{
*(struct logic_error *) D.2069 = exp;
}
catch
{
__cxa_free_exception (D.2069);
};
__cxa_throw (D.2069, (void *) &_ZTI11logic_error, 0B);
This is a problem, since exp (that contains cleanups) is withing the try
statement,
and gimplify_cleanup_expr expects that there never is a compound statement
between
cleanup and cleanup_point_expr (except for COND_EXPRs).
For comparison, with
void foo(bool b) {
throw logic_error(1);
}
exp is
TARGET_EXPR
In this case, however, stabilize_init will allow to pre-evaluate t1, and the
produced
code is (where exp' is exp with t1 replaced by tmp):
TARGET_EXPR
TARGET_EXPR ;
try
{
*(struct logic_error *) D.2069 = exp';
}
catch
{
__cxa_free_exception (D.2069);
};
__cxa_throw (D.2069, (void *) &_ZTI11logic_error, 0B);
Here gimplify_cleanup_expr has no problem, since t1 is outside of the try
statement.
Now the question is whether we can persuade throw_expr to also evaluate
(the relevant parts of) exp outside of the try statement. Answering this
question
is far beyond my understanding of c++ frontend; stabilize_init claims that
/* If the initializer is a COND_EXPR, we can't preevaluate
anything. */
if (TREE_CODE (t) == COND_EXPR)
return false;
which might suggest that it is not possible, but the statement is too vague for
me to
be sure.
If it is somehow possible, it would be much preferable. The other possibility
is to teach
gimplify_cleanup_expr to deal with try statements, which basically means to
rewrite it
completely from scratch.

I'm not sure whether the if should be fixed or the type of signo
should be changed to int. The first argument in the linux implementation
has the type of int.

The construct reported in this PR is a widely known and used C++ idiom:
Resource Acquisition Is Initialization (RAII). It is inappropriate for
-Wall to warn about it. However, the mechanism underpining it is so broad
that we would need more accurate measure to fix it.
Of course, the compiler (more precisely the middle-end) knows that the
destructor has a side-effect. But GCC middle-end tends to have little
knowledge of language specific idioms. Notice also that a is "used"
from a very high level abstraction point of view -- not from byte-fiddling
point of view. This is another instance of diagnostic PR better handed off
to the front-end.
