…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>
