[PATCH 4/7] tests: glr: prefer directives to warnings
Akim Demaille <[email protected]>
| Newsgroups | gmane.comp.parsers.bison.patches |
|---|---|
| Message-ID | <[email protected]> |
* tests/glr-regression.at: Use %expect and %expect-rr in the grammar
files, rather than accepting diagnostics.
This will make it easier to support other programming languages.
