PaoloS updated this revision to Diff 277531.
PaoloS added a comment.
Updated the test:
- the tests have been updated from the top of all the sub-patches together so that they are exactly the same as they would be if updated with the whole final patch.
- labels specific to the sub-extension have been added alongside the generic RISCVIB label (that activates all the sub-extensions) so that we can see how differently the patterns are matched with the specific subextension or with all of them together.
- the tests will probably fail if run by checking out the commit of a subextension and if updated they'll change. These tests are designed to work with the final squashed patch.
Added the pattern-matching for rori and roriw.
Added the correspondent tests.
