112 --no-params There are two lines of expected output; the first
113 is with DMGL_PARAMS, the second is without it.
114 --is-v3-ctor Calls is_gnu_v3_mangled_ctor on input; expected
115 output is an integer representing ctor_kind.

119 empty, to mean --format=auto. If it doesn't start with --, then it
120 may contain only a format name.
