It failed on Linux/x86-64:

/export/gnu/import/svn/gcc-test/src-trunk/gcc/testsuite/g++.dg/ext/attrib36.C:8:56:
warning: '__stdcall__' attribute ignored^M
/export/gnu/import/svn/gcc-test/src-trunk/gcc/testsuite/g++.dg/ext/attrib36.C:14:64:
warning: '__stdcall__' attribute ignored^M

I think this test should be limited to ilp32.

[Bug c++/43031] [4.5 Regression] internal compiler error: verify_gimple failed after non-trivial conversion error when crosscompiling Firefox

2010-02-15 Thread jason at gcc dot gnu dot org 


--- Comment #4 from jason at gcc dot gnu dot org  2010-02-15 22:43 ---
Right, the stdcall attribute prevents us from using TYPE_CANONICAL, so it's not
clear to useless_type_conversion that the type of T::A is the same as P::F. 
Specifically, they are distinct because P::F uses a typedef for L, whereas T::A
does not.

I guess we need to insert an explicit conversion, provide TYPE_CANONICAL even
in the presence of strong attributes, or both.

class T;
class L { };
class P : public L
{
  typedef void (__attribute__((__stdcall__)) T::*F) (L*);
  void f(bool aAdd);
};
class T
{
public:
virtual void __attribute__((__stdcall__)) A(L *listener) = 0;
virtual void __attribute__((__stdcall__)) R(L *listener) = 0;
};
void P::f(bool aAdd)
{
  F addRemoveEventListener = (aAdd ? T::A : T::R);
}


we seem to fail to unify pmf types when the stdcall attribute is applied.
