That works; a more future-proof way is writing it as
/* { dg-final { scan-assembler-not {\mld\M} } } */
which will also not match a future "ldlol" instruction (\m \M are like
\< \> in some other regular expression dialects; see
https://www.tcl.tk/man/tcl8.4/TclCmd/re_syntax.htm ).
Okay either way. Thanks,
