Bug ID: 23179
Summary: Warn on missing exports in microsoft mode?
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
Consider something like this:
struct CpuProfileDeoptFrame {
int script_id;
};
// XXX
//template class V8_EXPORT std::vector<v8::CpuProfileDeoptFrame>;
struct V8_EXPORT CpuProfileDeoptInfo {
std::vector<CpuProfileDeoptFrame> stack;
};
Unless the line marked XXX is present, cl will warn on this with
2>D:\src\v8\include/v8-profiler.h(31): warning C4251:
'v8::CpuProfileDeoptInfo::stack' : class
'std::vector<v8::CpuProfileDeoptFrame,std::allocator<_Ty>>' needs to have
dll-interface to be used by clients of struct 'v8::CpuProfileDeoptInfo'
2> with
2> [
2> _Ty=v8::CpuProfileDeoptFrame
2> ] (..\..\src\compiler\change-lowering.cc)
There's probably a good reason for that -- should we warn on this too?
