<pre>clang allows two var definitions with the same mangled name; only one var is
emitted:
$ cat test.cpp
extern "C" {
int _ZN2nm3abcE = 1;
}
namespace nm {
float abc = 2;
}
float foo() {
return _ZN2nm3abcE + nm::abc;
}
$ clang -emit-llvm -S -c test.cpp
[no errors printed]
$ cat test.ll
...
@_ZN2nm3abcE = global float 2.000000e+00, align 4
[int _ZN2nm3abcE definition is nowhere to be found]
