<pre>As Richard Smith mentioned <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - Incorrect mangling of member function with __restrict qualifier"
href="show_bug.cgi?id=17786#c4">http://llvm.org/bugs/show_bug.cgi?id=17786#c4</a> we do
not properly handle restrict qualifiers in this case.
This has ABI correctness implications:
#include <typeinfo>
#include <cstdio>
struct S {
const char *W() {
return typeid(this).name();
}
const char *X() __restrict {
return typeid(this).name();
}
const char *Y() const {
return typeid(this).name();
}
const char *Z() volatile {
return typeid(this).name();
}
};
int main() {
S obj;
printf("%s\n", obj.W());
printf("%s\n", obj.X());
printf("%s\n", obj.Y());
printf("%s\n", obj.Z());
}
