(By context-updates we understand programming language constructs such as goto instructions or function calls.) The context-updates synthesis follows two directions: an overapproximating phase that extracts a set of potential context-update constructs and an underapproximating phase that refines the results of the first step by testing the behaviour of the context-updates constructs produce","authors_text":"Adrian Riesco, Irina Mariuca Asavoae, Mihail Asavoae","cross_cats":["cs.LO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.PL","submitted_at":"2017-09-20T14:22:50Z","title":"Context-Updates Analysis and Refinement in Chisel"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1709.06897","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:870faea2e17c38e54d8f52171f81ebf3f4936f6f7a1b39327cb88752ce111891","target":"record","created_at":"2026-05-18T00:34:40Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"6fa1db422ebcba8134d3e00d4ec589f9fbefd1ffbb1c176a6087e223eaca8a08","cross_cats_sorted":["cs.LO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.PL","submitted_at":"2017-09-20T14:22:50Z","title_canon_sha256":"b9ab1abe7a543d75fd785a7849e09fc4ddcf867173eba13d9d4f677c6afb38a4"},"schema_version":"1.0","source":{"id":"1709.06897","kind":"arxiv","version":1}},"canonical_sha256":"576c094630d5d2ca35f8890462cdcdf8c4c3da032d8ff31893dfe43f1cdba013","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"576c094630d5d2ca35f8890462cdcdf8c4c3da032d8ff31893dfe43f1cdba013","first_computed_at":"2026-05-18T00:34:40.145654Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:34:40.145654Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"AhfZkUMSGvnHk1Cx2ieXHy3qG+hkLN2svlX5uSb5fs9mDX3UPuOUSV274MNwGDRQWFkaLU6+gAFcpAuvIrZXAA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:34:40.146129Z","signed_message":"canonical_sha256_bytes"},"source_id":"1709.06897","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:870faea2e17c38e54d8f52171f81ebf3f4936f6f7a1b39327cb88752ce111891","sha256:b7fc624ee4c93f737c0a6b518608c2f244509ee75e10884f09c7140f19efac01"],"state_sha256":"d75853d53503fed9ded4616fedbc2d1da178be8d8b494b68f98b41365a913fba"}
