Bug ID: 17152
Summary: [-cxx-abi microsoft] Mangle local types more
accurately
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: LLVM Codegen
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
consider:
template <class T> struct A {
// in A<X>, the following is allowed because the type with no linkage
// X is named using template parameter T.
friend void f(A, T){}
};
template <class T> int *g(T t) {
static int x = 0;
A<T> at;
f(at, t);
return &x;
}
int main() {
class X {} x;
return *g(x);
}
we mangle:
?f@@YAXU?$A@VX@?1??main@@@@@VX@?1??main@@@@Z
?x@?1???$g@VX@?1??main@@@@@YAPEAHVX@?1??main@@@@Z@4HA
we want:
?f@@YAXU?$A@VX@?1?main@@@VX@?1??main@@9@@Z
?x@?1???$g@VX@?1?main@@@YAPEAHVX@?1??main@@9@@Z@4HA
