110 | Supported options: |
111 | --format=<name> Sets the demangling style. | |
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. | |
116 | --is-v3-dtor Likewise, but for dtors. | |
a54ba43f | 117 | |
820542c9 DD |
118 | For compatibility, just in case it matters, the options line may be |
119 | empty, to mean --format=auto. If it doesn't start with --, then it | |
120 | may contain only a format name. | |
