Bug #: 12067
Summary: static global of class type not initialized in c++11
mode
Product: clang
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++0x
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
Given
struct nsMemoryImpl {
virtual void f();
};
static nsMemoryImpl sGlobalMemory;
void f(nsMemoryImpl *);
void g() {
f(&sGlobalMemory);
}
clang normally produces
@_ZL13sGlobalMemory = internal global %struct.nsMemoryImpl { i32 (...)**
bitcast (i8** getelementptr inbounds ([3 x i8*]* @_ZTV12nsMemoryImpl, i64 0,
i64 2) to i32 (...)**) }, align 8
but with -std=c++11
it produces
@_ZL13sGlobalMemory = internal global { [8 x i8] } undef, align 8
