Extend the relax AST with a predicate node and teach the lexer/parser to recognise predicate applications such as `@before(...)` and `@after(...)`. Add `map_predicate` support to the AST so predicate names can be converted before expansion. Parse `before` and `after` into edge predicates, then attach the parsed predicate to every edge produced by the decorated relax expression.
Extend `diy7` cycle searching to recognise predicate-decorated boundary edges. `@after(...)` predicates at the end of a candidate edge sequence and `@before(...)` predicates at the start of the existing suffix are matched against the adjacent concrete edge before the search continues. Once predicates have been checked, remove them from candidate cycles before handing them to the normal test generator.
Add a `diy7 -unfold-only` option that parses and expands `-relax`, `-safe`, and `-reject` inputs without running cycle generation.
Move invalid-relax filtering after the relax set definition so expanded relaxations can be normalised through `Set`.
…d both-type- communication.
…tests. For `...;po` and `...;po;[M]` in cat, we append the external communication edges `Obs` in the translation. Similarly for `po;...` and `[M];po;...`, we prefix `Obs`.
Add back `Amo.StAdd` and `Amo.LdAdd` as the representation for all other atomic operation. We also remove `[Q Amo.* ***]` as `Q` cannot apply to `Amo.*`
Split DumpAll's check/dump path into explicit and clear stages: atom variation, edge resolution, normalisation, duplicate detection, test construction, and final dumping. This makes the ordering clearer and avoids rebuilding the same test separately for each scope/name variant. It also massively simply error handling. minor: - Change `mk_info` from a function over the normalised edge list into prepared metadata passed with the candidate. - Make `Edge.varatom` return the list of atomic variations directly, leaving edge resolution to the DumpAll pipeline. This keeps varatom focused on atom enumeration and makes resolve_edges placement explicit.
Add earlier candidate checks in alt.ml before calling into DumpAll/test construction - It rejects candidates that already exceed the configured process or per-procedure instruction limit - It checks both (1) the immediate adjacent boundary and (2) the effective non-pseudo memory-access boundary when concatenating relaxation. - Rework on rejecting cycle or cycle segment. Replace the old reject substring/span helpers with direct cycle/list matching helpers used by both partial generation and last-minute checking. For the final check, we apply a simpler and more readable algorithm by checking if the `cycle @ cycle` contains any reject edge lists, which is much more efficient and readable compated to previous `cut` based.
Store -rejectlist arguments as a list and parse them with the same unfolding path used by relax and safe lists. This lets repeated -rejectlist options accumulate and deduplicate after expansion. Add unfold-only tests covering reject-list choice, optional edges, sequences, annotations, duplicate removal, and repeated -rejectlist arguments.
Add more consecutive none fault check. This rule out undesired situations where a memory access does not fault but the consecutive one faults.
Add gen/libdir/memtag.conf for generating forbidden tests for memory tags.
