Remove an old workaround that was kept around for ABI-compatibility on x86-64 between different LLVM versions. This means LLVM r67588 is required if you want to compile for x86-64, otherwise the backend will assert when you try to return e.g. struct { int i; char c; } from a function. (In particular, this is no longer compatible with LLVM 2.5) It also means that any code returning small structs on x86-64 will probably need to be recompiled in order to be linkable to code compiled with this change.

module foreach11;

extern(C) int printf(char*, ...);

void main() {
    char* last = null;
    printf("The addresses should remain constant:\n");
    foreach (c; "bar") {
        auto a = {
            printf("%x '%c'\n", c, c);
            printf("ptr = %p\n", &c);
            if (last)
                assert(last == &c);
        };
        a();
        last = &c;
    }
}
