The following test case, when compiled with g++ -O, has a return
value of 1 (instead of the correct value of 0):
struct test
{
int type;
char buffer[4242]; /* should trigger pass-by-reference */
};
int flag = 0;
struct test
reset (void)
{
struct test retval;
retval.type = 1;
return retval;
}
struct test
test (void)
{
struct test result;
result.type = 0;
for (int i = 0; i < 2; ++i)
{
struct test candidate = reset ();
if (flag)
result = candidate;
}
return result;
}
int
main (void)
{
struct test result = test ();
return result.type;
}
The reason for this appears to be a bug in the tree-nrv (named
return value) optimization pass. Before tree-nrv, the function
test looks like:
struct test candidate;
int i;
int flag.0;
<bb 2>:
<retval>.type = 0;
flag.0 = flag;
i = 0;
<L0>:;
candidate = reset () [return slot optimization];
if (flag.0 != 0) goto <L1>; else goto <L2>;
<L1>:;
<retval> = candidate;
<L2>:;
i = i + 1;
if (i != 2) goto <L0>; else goto <L5>;
<L5>:;
return <retval>;
After tree-nrv, we have:
struct test candidate;
int i;
int flag.0;
<bb 2>:
<retval>.type = 0;
flag.0 = flag;
i = 0;
<L0>:;
<retval> = reset () [return slot optimization];
if (flag.0 != 0) goto <L1>; else goto <L2>;
<L1>:;
<L2>:;
i = i + 1;
if (i != 2) goto <L0>; else goto <L5>;
<L5>:;
return <retval>;
The return value of reset has been redirected directly
into the return value slot of test, instead of the local
variable candidate. tree-nrv.c has some code that is
apparently intended to prevent this type of thing; I'm
not sure why that didn't work here.
The bug occurs (at least) in GCC 4.1.1 and current mainline.

Can we do anything to work around this issue?
Is there an option, for example, to turn off just named return value
optimisation? (I did a quick search of the manual but couldn't find anything.)

------- Comment #3 from pinskia at gcc dot gnu dot org 2007-01-29 00:12 -------
A possible work around is to create another temp variable of type struct test.
Such that the function test looks like:
struct test
test (void)
{
struct test result;
struct test temp;
result.type = 0;
for (int i = 0; i < 2; ++i)
{
struct test candidate = reset ();
if (flag)
result = candidate;
}
temp = result;
return temp;
}
---------------------------------------
The bug is because NVR is applied twice, once in the front-end and once in
tree-nvr. If the front-end already applied NVR, we should not apply it again
in tree-nvr.
Looking into fixing this bug later tonight.

Re. comment #2
Thomas, there is no option to turn off the NRV pass. I don't know why there
isn't one, but I believe there should be. Looks like an oversight.

You can't because the NVR optimization in the front-end also removes the copy
constructor call if would have been called. The question is how do you remove
the copy constructor after optimizations have might inlined it. Unless you do
NVR before any other optimization might have happened.

------- Comment #7 from spark at gcc dot gnu dot org 2007-03-13 16:15 -------
tree-nrv code doesn't see:
<bb 2>:
<retval>.type = 0;
because it only looks at GIMPLE_MODIFY with the operand 0 as the return value.
In this case, there's GIMPLE_MODIFY of the component of the return value
hence not all modification to the return value.
The following patch seems to get around the problem:
Index: tree-nrv.c
===================================================================
--- tree-nrv.c (revision 122871)
+++ tree-nrv.c (working copy)
@@ -163,6 +163,12 @@ tree_nrv (void)

result)
+ /* If there's any MODIFY of component of RESULT,
+ then bail out. */
+ return 0;
}
}
I'm not sure this is sufficient - can there be any other
gimple statement combination that modifies only part of RESULT ?

Use get_base_address (GIMPLE_STMT_OPERAND (stmt, 0)) == result. (Verify if
get_base_address does not return NULL, if it's the result_decl, otherwise
replicate the loop therein).

How does this one look ? If it looks reasonable, I'll start the testing with
the mainline.
