Summary: missed optimization for inline virtual methods
Product: clang
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
Given the translation unit
struct foo {
virtual void bar();
virtual void baz() {}
};
void zed() {
foo b;
b.baz();
}
we currently produce
define linkonce_odr void @_ZN3foo3bazEv
it should probably be available_externally. Given that the function is virtual
and we know we will have a vtable in some other translation unit, we can
produce this one as available_externally.
