>Description:
If i compile the source below and look at the generated code, i see
that the reference to the rcp::EntryRCPID constructor is said to be
in the global namespace, _not_ the rcp namespace.
If the typedef is removed, then the external reference moves back
to the rcp namespace. Oddly, if the EntryRCPID class is made non-virtual
by removing the destructor declaration, and if i turn on debugging,
then the external name also moves back to the rcp namespace.
>How-To-Repeat:
---------------------------------------------------------------------
namespace rcp {
struct EntryRCPID
{
EntryRCPID();
virtual ~EntryRCPID();
};
typedef EntryRCPID EntryRCPID;
}
void xyzzy()
{
rcp::EntryRCPID x;
}
---------------------------------------------------------------------
$ ./cc1plus -quiet x.cc
$ c++filt < x.s | grep EntryRCPID
call EntryRCPID::EntryRCPID()
call EntryRCPID::~EntryRCPID()
If i comment out the destructor declaration in the above and add -g
to the compilation, i get instead the following results:
$ ./cc1plus -g -quiet x.cc
$ c++filt < x.s | grep EntryRCPID
.stabs "EntryRCPID:T(0,25)=s1operator=::(0,26)=#(0,25),(0,27)=&(0,25),(0,28)=*(0,25),(0,29)=&(0,25),(0,21);:rcp::EntryRCPID::operator=(rcp::EntryRCPID const&);2A.;__base_ctor::(0,30)=#(0,25),(0,21),(0,28),(0,29),(0,21);:rcp::EntryRCPID::EntryRCPID(rcp::EntryRCPID const&);2A.;__comp_ctor::(0,30):rcp::EntryRCPID::EntryRCPID(rcp::EntryRCPID const&);2A.;__base_ctor::(0,31)=#(0,25),(0,21),(0,28),(0,21);:rcp::EntryRCPID::EntryRCPID();2A.;__comp_ctor::(0,31):rcp::EntryRCPID::EntryRCPID();2A.;;",128,0,0,0
