           Summary: C++ IA64 ABI: 3.1.4: sometimes pointer to temporary
                    return value is implicit first parameter preceding
                    “this”
           Product: gcc
           Version: 3.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P1
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: Vyatcheslav dot Sysoltsev at intel dot com
                CC: gcc-bugs at gcc dot gnu dot org

According to C++ Itanium ABI (http://www.codesourcery.com/cxx-
abi/abi.html#calls) clause 3.1.4 if the return value type has a non-trivial 
copy constructor or destructor the caller allocates space for a temporary, and 
passes a pointer to the temporary as an implicit first parameter preceding both 
the “this” parameter and user parameters. The callee then constructs the return 
value into this temporary.
	I tried gcc 3.2 on United Linux 1.0 and found that this rule is 
violated, “this” pointer is always r32 and the value returned in different ways 
but never the way described in this part of ABI.
	Here is a test case that demonstrates the problem:
test.cc:
#include <stdio.h>
#include <stdlib.h>

struct ConstructedObject {
    ConstructedObject() {};
    ~ConstructedObject() {};
    ConstructedObject(const ConstructedObject &from) {};
};

struct FrameworkObject {
    ConstructedObject action();
};

ConstructedObject FrameworkObject::action() {
    void *r32, *r33;

    asm("mov %0 = r32\nmov %1 = r33" : "=r"(r32), "=r"(r33) : );
    printf("In FrameworkObject, this = %lx, r32 = %lx, r33 = %lx\n", this, r32, 
r33);
    if (this != r33) {
        printf ("Test failed\n");
        exit(-1);
    }
};

int main()
{
    FrameworkObject slawa;
    slawa.action();
    return 0;
}

command line: g++ -g -O0 test.cc && a.out
Output:
In FrameworkObject, this = 60000fffffffb270, r32 = 60000fffffffb270, r33 = 
6000000000000de0
Test failed

Test fails because according to ABI r32 is a placeholder for returned object, 
r33 is “this” pointer.
Because gcc violates C++ Itanium ABI such way, binaries built by gcc can be 
incompatible with binaries built by other compiler. To avoid such a situation 
C++ ABI standard was created. All compilers must honor it, gcc must in greater 
degree as the most popular one, that's why I set P1 priority.

The bug is reproducible both with gcc 3.2 and gcc 3.4.

Does this happen on the mainline with -fabi-version=0?

Is this a regression? There is no indication if it was tested on 2.95. I know 
the ABI is changed, but if the program succeeds, it's still a regression wrt 
the old ABI.

Ah sorry, I didn't notice the program just tests Itanium ABI compliance.
