          Issue ID: 16995
           Summary: __traits(getUnittests) doesn't work with separate
                    compilation
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: atila.neves gmail.com

foo.d:
-----
void main() {
    import bar;
    foreach(ut; __traits(getUnitTests, bar)) ut();
}
-----

bar.d:
-----
unittest { assert(1 == 2); }
-----


# compile all at once
dmd -unittest foo.d bar.d # fine


# compile separately
dmd -c -unittest foo.d
dmd -c -unittest bar.d
dmd foo.o bar.o
foo.o:foo.d:function _Dmain: error: undefined reference to
'_D3bar16__unittestL2_531FZv'
collect2: error: ld returned 1 exit status
--- errorlevel 1


objdump shows me that bar.o has a '_D3bar14__unittestL2_1FZv' symbol, which is
nearly, but not quite, what foo.o is trying to call.
