The example below has worked fine with clang-15 and also with clang16 branch of a week ago.
```c
#define XREF_NOTE \
"" "\n"\
" .type _frr_xref_note,@object" "\n"\
" .pushsection .note.FRR,\"a\",@note" "\n"\
" .p2align 2" "\n"\
"_frr_xref_note:" "\n"\
" .long 9" "\n"\
" .long 16" "\n"\
" .ascii \"XREF\"" "\n"\
" .ascii \"FRRouting\\0\\0\\0\"" "\n"\
" .quad __start_xref_array-." "\n"\
" .quad __stop_xref_array-." "\n"\
" .size _frr_xref_note, .-_frr_xref_note" "\n"\
" .popsection" "\n"\
"" "\n"\
void foo(void) {
asm(XREF_NOTE);
}
```
```
