…ng wrappers. (#989) This is a bit of everything in one go, but what I was trying to do was isolate the case seen in [this Kompass test](https://github.com/runtimeverification/kompass/blob/master/src/tests/integration/data/token/spl-token/show/spl_token_domain_data-fail.main.expected) that was discussed in #987. The `volatile_load` is coming from `Box::new` which we are not supporting right now as that does heap allocation. This PR: - Adds failing tests for statics (not decoding properly) - Adds a failing test for `Box::new` - Supports sound transmutation between transparent wrappers (in `#[repr(rust)]` case and their wrapped type. Seen as a `thunk` earlier in the `Box::new` proof and I thought I would solve it now. There are tests for this changed from failing passing in the commit history. So the `volatile_load` is expected to fail until we figure out some support for the things that these tests fail on. This is not blocking any work now so I think it is fine just to add the failing tests --------- Co-authored-by: automergerpr-permission-manager[bot] <190534181+automergerpr-permission-manager[bot]@users.noreply.github.com>
## Summary - Skip LLVM backend `test_exec_smir` tests in CI — keep Haskell only, since it's the backend used for proving and bugs there have higher impact - Skip `test_prove_termination` in CI — the same 19 programs are already executed via `test_exec_smir[*-haskell]` This is done via a pytest `-k` filter in the CI workflow only — **no test code is modified**, so all tests remain available for local development. **Deselected: 58 of 247 tests** (39 LLVM exec_smir + 19 prove_termination) ## Risk Analysis - LLVM backend regression will be missed in the previous test, which should be handled by future test framework refactoring. But if we don't add new `exec_smir` test or add new `exec_smir` test with llvm to update expected files, the result is the same as we run CI before. - `test_prove_termination` just uses `prove-rs` to validate the termination, which is the same as the comparison with the current expected files. I believe that there is no risk to remove them in this way. ## Expected CI time reduction ~2h37m → ~1h20m (based on [this run](https://github.com/runtimeverification/mir-semantics/actions/runs/22658250856/job/65672639933?pr=957)) ## Test plan - [x] Integration tests pass with the `-k` filter applied - [x] Verify CI time improvement Resolves #971 (Phase 1) --------- Co-authored-by: Everett Hildenbrandt <everett.hildenbrandt@gmail.com> Co-authored-by: dkcumming <daniel.cumming@runtimeverification.com>
This PR adds basic support for [IEEE 754 Floating Point Numbers](https://en.wikipedia.org/wiki/IEEE_754), specifically `f16`, `f32`, `f64`, `f128`. These are already supported in K through builtins (see [domains.md](https://github.com/runtimeverification/k/blob/master/k-distribution/include/kframework/builtin/domains.md#ieee-754-floating-point-numbers)). This work is derivative of the implementation in the c-semantics (see ieee754.k in that repository). In particular: - 6 tests are added that tests each type for equality, negation, comparison, casting, arithmetic, and special values (NaN and Infinity) - Documentation and helpers for floats are added to numbers.md - Decoding is added for floats from bytes in numbers.md (see note on haskell backend below) - Semantic rules for arithmetic are extended for floats in data.md ### Haskell Backend The haskell backend has no `Float` builtins (no Float.hs in [kore/src/Kore/Builtin/](https://github.com/runtimeverification/haskell-backend/tree/master/kore/src/Kore/Builtin)). This means `kore-exec` crashes with "missing hook FLOAT.int2float" when attempting to evaluate a float. The booster avoids this by delegating Float evaluation to the LLVM shared library via `simplifyTerm` in [booster/library/Booster/LLVM.hs](https://github.com/runtimeverification/haskell-backend/blob/master/booster/library/Booster/LLVM.hs). Prior to being able to decode floats, they were left as `UnableToDecode` which did not throw and error in the exec-smir test suite for `--haskell-backend`. Now that they are able to be decoded, the haskell backend throws on these decoded values. So I am now skipping any tests with decoded floats for exec-smir with haskell backend.
## Summary - remove the redundant `#forceSetLocal` helper now that `#setLocalValue` no longer guards on mutability - route moved-writeback and zero-sized-local initialization through `#setLocalValue` - drop the obsolete interior-mutability fast-path introduced by the old branch state ## Why After rebasing onto current `origin/master`, the original interior-mutability writeback fast-path became obsolete: `#setLocalValue` already permits writes to immutable locals, so the extra helper and its special-case callsites no longer buy any behavior. This PR turns the branch into the cleanup that current master actually needs. ## Validation - `make build` - `cd kmir && uv run pytest src/tests/integration/test_integration.py -v --timeout=600 -k "interior-mut or transmute-maybe-uninit-fail" -x` - 4 passed, 261 deselected - started `make test-integration`; no early failures before stopping due runtime
…pping strategy (#988) ## Summary - Fixes stuck execution caused by incorrect projection chains from `#pointeeProjection` - Root cause: non-deterministic overlap between struct and array rules — when source is a struct and target is an array (or vice versa), both rules match and the LLVM backend's choice determines correctness - Commit history shows why `[priority(45)]` alone doesn't work (it fixes one case but regresses the other) - Fix: always unwrap the source type first; target-side unwrapping deferred to `#pointeeProjectionTarget` - Reproducer from @dkcumming's review comment (minimal `Wrapper([u8; 2])` cast) ## Test plan - [x] `ptr-cast-wrapper-to-array` passes (new reproducer) - [x] `iter_next_2` still passes (regression test for opposite overlap: `[Thing;3] → Thing`) - [x] Full integration test suite passes --------- Co-authored-by: Daniel Cumming <124537596+dkcumming@users.noreply.github.com> Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
…on (#813) ## Summary Fix two issues preventing correct handling of zero-sized function item types (e.g., non-capturing closures): 1. **`#zeroSizedType` did not recognize `typeInfoFunType`** (`types.md`) — Function items are inherently zero-sized (`#elemSize` already returns 0), but `#zeroSizedType` returned `false`, preventing `rvalueRef` from materializing uninitialized closure locals. 2. **`#decodeConstant` had no rule for `typeInfoFunType`** (`data.md`) — Zero-sized function constants fell through to the `thunk` wrapper instead of decoding to `Aggregate(variantIdx(0), .List)`. ## Evidence `closure-staged.rs` with `terminate-on-thunk`: | | Steps | Result | |---|---|---| | Before | 44 | `thunk(#decodeConstant(constantKindZeroSized, _, typeInfoFunType(_)))` | | After | 266 | `#EndProgram` | --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com> Co-authored-by: Daniel Cumming <124537596+dkcumming@users.noreply.github.com>

The inner-case1b-keys-match-custom4-spl rule accepts OWNER_KEY == OWNER_KEY together with Err(Custom(4)) and immediately continues, which bypasses the assertion behavior that should fail when keys match but the result is still Custom(4). This makes the SPL lemma unsound for this mismatch case and can let an incorrect validate_owner implementation pass symbolic proofs.

This rule (and the corresponding inner-case3-spl) ignores is_signer via _IS_SIGNER, so contradictory states are accepted: e.g. is_signer == true with Err(MissingRequiredSignature) (or false with Ok(())) still rewrites as success instead of surfacing an assertion failure. That weakens inner_test_validate_owner checking and can hide signer-handling regressions in proofs.

Rust as casts from float to int are saturating for NaN/out-of-range inputs, but this rule uses Float2Int followed by integer truncation, which models truncation/wrapping behavior instead of saturation. Programs such as f32::INFINITY as i32 or NaN as u8 will be mis-modeled, producing incorrect proof outcomes around numeric bounds.

Adapted from the p-token version (PR #1001). Key differences from the p-token lemma: - spl-token AccountInfo uses raw Aggregate values instead of p-token's PAccountAccount/PAcc wrappers, so the intercept rules extract individual fields (key, is_signer, owner) from AccountInfo using field projections (field 0, 5, 3 respectively) - Case rules match pre-extracted Values directly instead of destructuring PAccount wrappers - Uses _IS_SIGNER wildcard for symbolic bool handling (spl-token's is_signer may be a symbolic BoolVal) - Case 1b handles keys-match + Err(Custom(4)) path via LHS pattern match (avoids booster sort injection errors from requires ==K) - Cases 8-10 (multisig signer-checking) fall through to small-step execution (sufficient for n==1) Also fixes #forceSetLocal -> #setLocalValue in spl-token.md for compatibility with origin/master which removed the redundant helper. Proof result: test_validate_owner_multisig PASSED with 27 nodes in 2886s (vs 123 nodes / 4877s without lemma, 41% speedup). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
