failing test
Consider:
Nicos-MacBook-Pro:Release thakis$ cat test.h
namespace foo {
template <typename _Tp>
struct __is_pod {
enum {
__value = 1
};
};
}
Nicos-MacBook-Pro:Release thakis$ cat test.cc
template <typename T>
struct my_is_pod {
static const bool value = __is_pod(T);
};
int f() {
return my_is_pod<int>::value;
}
Nicos-MacBook-Pro:Release thakis$ clang -x c++-header test.h -o test.h.gch
-stdlib=libstdc++
Nicos-MacBook-Pro:Release thakis$ clang -include test.h -c test.cc
-stdlib=libstdc++
test.cc:3:38: error: 'T' does not refer to a value
static const bool value = __is_pod(T);
^
test.cc:1:20: note: declared here
template <typename T>
^
1 error generated.
But this passes:
Nicos-MacBook-Pro:Release thakis$ rm test.h.gch
Nicos-MacBook-Pro:Release thakis$ clang -c test.cc -std=c++11 -include test.h
In file included from <built-in>:188:
In file included from <command line>:1:
test.h:3:8: warning: keyword '__is_pod' will be made available as an identifier
for the remainder of the translation unit [-Wkeyword-compat]
struct __is_pod {
^
1 warning generated.
r110868 looks like it fixed this in the other direction, and
test/PCH/cxx-traits.cpp tests that other direction. The attached patch adds a
test (but not a fix) for the still-buggy direction described above.</pre>
