Hi all.
This patch caused g++.dg/ext/dllimport7.C to regress (in one subtest) between
4.3.2 and 4.3.3 on Cygwin, although it could be that the testcase is out of
date.
// { dg-do compile { target i?86-*-cygwin* i?86-*-mingw*} }
// Report errors on definition of dllimport'd static data member .
struct Baz
{
Baz(int a_ =0) : a(a_) {}
int a;
};
class __declspec(dllimport) Bar
{
public:
enum {one = 1};
static const int two = 2;
static const int three;
static const Baz null_baz;
};
const int Bar::three = 3; // { dg-warning "redeclared without dllimport"
}
// { dg-error "definition of static data" "C++ specific error" { target
i?86-*-cygwin* i?86-*-mingw* } 21 }
const Baz Bar::null_baz; // { dg-warning "redeclared without dllimport"
}
// { dg-error "definition of static data" "C++ specific error" { target
i?86-*-cygwin* i?86-*-mingw* } 24 }
int foo()
{
Bar foobar;
const int* baz = &Bar::two;
int a = foobar.two;
int b = foobar.three;
int c = foobar.null_baz.a;
return (a + b + c + *baz);
}
Both the dg-error clauses now fail; previously (4.3.2), only the second one
failed. Reverting the patch causes the first dg-error (line 21) to pass again
by restoring the error message
/gnu/gcc/release/gcc4-4.3.3-1/src/gcc-4.3.3/gcc/testsuite/g++.dg/ext/dllimport7.
C:21: error: definition of static data member 'Bar::three' of dllimport'd class
I'm not sure why that should be a problem in the first place, so I don't know
if the underlying issue is now fixed and not an error any more. Anybody?
