<pre>
    All three directives allow string concatenation with GNU as while the llvm assembler rejects the latter two.

At least for `.asciz`, the GNU as manual is explicit:

> Note that multiple string arguments not separated by commas will be concatenated together and only one final zero byte will be stored. 

```
$ cat test.c
asm(".ascii \"a\" \"b\"");
asm(".asciz \"a\" \"b\"");
asm(".string \"a\" \"b\"");

$ clang -c -o /dev/null /tmp/test.c 
<inline asm>:2:12: error: unexpected token
.asciz "a" "b"
           ^
<inline asm>:3:13: error: unexpected token
.string "a" "b"
            ^
2 errors generated.
