--- Comment #4 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Thanks.
For unclosed delimiter tokens in source we try to add a secondary location
showing the opening corresponding delimiter. So maybe the ideal here would be
something like:
$ ./gcc/crab1 test.rs -frust-crate-attr="(option1" -frust-crate-attr="option2("
-frust-crate-attr="option3("
crab1: error: unexpected token ‘end of file’ - expecting closing delimiter ‘)’
(for a delimited token tree)
argument[2] | -frust-crate-attr="(option1"
~ ^
The "end of file" wording is rather weird here too, maybe just:
crab1: error: expecting closing delimiter ‘)’ (for a delimited token tree)
argument[2] | -frust-crate-attr="(option1"
~ ^
(mostly just brainstorming here)
