…nd oxk - inf_model: drop per-element swiglu/geglu pass that the full-vector pass immediately overwrites, and the byte-identical duplicate attention block in oc_inf_model_forward_batch that ran the whole attention pass twice - oxk_avx512: drop dead first loop in oc_oxk_dot_q8_0_q8_0_avx512_vnni whose accumulator was discarded before the second loop recomputed it - glm_arch/arch_forward: drop never-compiled OC_*_TEST_STUBS sections No behavior change; batch forward now does one attention pass instead of two. Full suite: 2923/2923 passing.
Replace 16 hand-rolled per-type dequant/pack functions with two DEFINE_PLAIN_DEQUANT / DEFINE_PLAIN_PACK macro families plus shared LE load/store helpers (f32/u64/bf16). Same validation, same loop bodies, same byte layout; test_quant VAL-QUANT-008/016 bit-exactness suites still pass (44/44), full suite 2923/2923.
Remove the 2.6 MB prebuilt libcriterion.a and 9k lines of vendored headers in favor of tests/framework.h + tests/framework_main.c (~600 lines total), implementing exactly the API surface the suite uses: Test() auto-registration, cr_assert*/cr_expect* families with optional messages, .description/.disabled extras, cr_skip_test, fork-per-test isolation, --filter/--list/--xml/--jobs. - Kills the glibc >= 2.38 pin that forced ubuntu-24.04 in CI - macOS no longer needs brew criterion; the runner links only libc/libm/libpthread - Drops 5 dead <criterion/redirect.h> includes - Updates Makefile, CONTRIBUTING.md, and both oxidize-c workflows All 2927 tests pass locally under the new runner (no sanitizer); the full ASan+UBSan matrix runs in CI.
308 trivial Test() bodies that only call fn(NULL) / assert OC_ERR_INVALID_ARG become OC_TEST_NULL_SAFE / OC_TEST_REJECTS_NULL one-liners in framework.h. The exercised expressions stay visible at the call site; test count and coverage unchanged. 2927/2927 passing.
- New src/format/tokenizer_common.h (private): OcU64Map open-addressing map + oc_pair_key + oc_tokenizer_string_array - tokenizer_bpe.c / tokenizer_tiktoken.c drop byte-identical duplicate u64map implementations (~250 lines) - bpe/sp/wp drop three copies of the GGUF string-array loader (~66 lines) - Bit-exact VAL-TOK tokenizer suites pass (46/46)
Master's sampling.rs top-k heap commit landed unformatted; CI's newer rustfmt formats the let-chain and collect differently than the committed text. Apply canonical formatting so 'Check formatting' passes again.
qwen/mistral/gemma/phi reference engines share byte-identical blocks: RMSNorm (12 sites), row-major matvec (28 sites), per-head RoPE (8 sites), tanh-GELU (2 local defs). Extract to static-inline helpers in src/model/arch_ops.h. Public API and forward-pass semantics unchanged; per-arch tests pass (62/62).
embed_token / matvec / attention_head existed as byte-identical static copies in llama.c, arch_forward.c, and glm_arch.c (the latter two even documented the duplication). Extract into private src/model/ llama_session_ops.h; llama.c keeps only its gemma4-scale + muse embedding post-processing wrapper. Full suite 2929/2929, including the prefill-parity invariants.
Delete pub functions with zero callers across the whole workspace: - kernels/transposed.rs: the entire quantized-transposed gemv family (qk/q4_k/q6_k/q8_0, gemv_quantized_f32_transposed dispatcher, q4 AVX2/AVX-512 accumulate helpers) — only gemv_f32_transposed is live (dflash, cpu_kernels, CUDA dispatch) - activation.rs: rms_norm_gemv_f32_transposed, layer_norm_f32, scaled_dot_product_attention_f32 (test-only) - gemm.rs: gemm_i8, gemm_i4 (+cpu variants, unpack_i4), linear_activation_f32 (test-only) - q_kernels.rs: gemv_qk_f32_fused (0 callers) - gemm_decode.rs: dot8_f32_avx2 (was #[allow(dead_code)]) - cpu_kernels.rs: CpuWorkspace, fused_rms_norm_gemv_f32_transposed, matmul_reuse_workspace, dot_product_avx512_or_scalar (self-referenced only); keep dot_product_avx2_or_scalar (activation_stats) and the public error/kernel-registry types Their unit tests are removed with them; remaining coverage: oxidize-core 642 passed. clippy -D warnings clean (one pre-existing master warning).
GgufMetadataValue::as_u32/as_f32 now live next to the enum; the byte-identical 10-arm lookup matches in inference.rs (u32 + array-max + f32), format/tokenizer.rs, and mlx_inference.rs collapse to one-liners. dflash/eagle3/fingerprint keep their local coercions (different accepted type sets). Tests: oxidize-core 642 passed.
oc_gemv_dispatch! stamps the shared wrapper skeleton (3-way shape validation, PARALLEL_GEMV_MIN_OPS row-parallel/serial dispatch) that was hand-copied in every per-quant wrapper; the per-row closure (AVX2 dispatch + scalar fallback) stays verbatim at each call site. Converted q4_k / q6_k / iq4_xs (+ iq4_nl_q8 kept hand-written: its wrapper owns the activation quantization). Kernels themselves untouched. oxidize-core 642 tests pass, clippy clean.
oc_gemm_decode_dispatch! stamps the 6 gemm_*_decode_once wrappers (validation + AVX2 fast-path hook + row-major panel compute + transpose epilogue); per-quant row-compute closures stay verbatim at each site. Kernel math untouched. 642 tests pass, clippy clean.
- Doc comments on macro invocations (rustdoc can't attach them) become regular comments at the q_kernels/gemm_decode dispatch sites - generation.rs: the constant assert that broke clippy -D warnings on master (all 3 OSes) becomes a const-evaluated check - Full workspace clippy is now clean, unblocking the failing 'CI' workflow that master has been failing since PR #42
setup_tiny_model was copy-pasted in 4 test files (inf_forward, gen_loop, layer_range, layer_wise) with only context_size differing (32 vs 64). Now one oc_test_setup_tiny_model(model, ctx) in tests/tiny_model.h. Same deterministic weights, same tests, same coverage. 2929/2929 pass.
The four generation streams (Speculative/Mtp/Eagle3/plain) each carried byte-identical emit_token stop-sequence logic (4 copies) and update_speculation_health bookkeeping (3 copies). Extract StopTracker (bounded recent-token ring + stop matching) and SpeculationHealth (drafted/accepted totals, zero-accept streak, disable rule); streams delegate. One behavior-neutral clone is added in GenerationStream's poll_next to satisfy the borrow checker. 642 tests pass, clippy clean.
9 identical OnceLock env-flag functions (OX_GPU_LAYER_Q8K, LMHEAD_Q8K, GEMV_MW, FUSED_MMQ, FUSED_QKV, FUSED_MW, FFN_FUSE, BATCHED_DECODE) each collapse to a one-line macro invocation in backends/cuda.rs. Same read-once semantics, same polarity rules. clippy clean, 642 tests pass.
llama_rope_dispatch (3-way YaRN/norm-pairs/plain, 4 duplicated copies across forward and prefill) and llama_qk_norm_heads (QK-norm loops, 2 copies) become single static helpers used by both paths. Prefill-parity tests pass (muse_glimmer, qwen35_forward, longcat); 2929/2929 total.
oc_arch_forward_glm / oc_arch_forward_hunyuan and their 14 static helpers (~800 lines) were never reachable: no loader populated their sessions, llama.c's dispatch never selected them, and no test executed them (test_glm_arch covers config parsing, version strings, and arch enums only). GLM/Hunyuan inference runs through the llama.c session paths. Config parsing, defaults, version mapping, and arch-registry entries are kept and tested (21/21 glm_arch tests pass).
Remove from the index (kept locally via .gitignore): - rust_out (4.3 MB compiled ELF) and a 5 MB manylinux wheel in dist/ - results/ bench logs: one-off llama.cpp/oxidize timing runs - evidence/: task-run QA transcripts - .firecrawl/: research scrapes (already gitignored, still tracked) - .cursor/debug-49b0b9.log No source, docs, or feature files affected. The wheel/ELF are rebuild products; results and evidence are stale local run outputs.
The AVX2 fast path is cfg'd to x86; on aarch64 (macOS CI) the closure param was unused. Reference it unconditionally on the scalar path.
The EMIT / EMIT_U8/U32/U64/F32 / EMIT_KV_STR_KEY family was redefined (and #undef'd) 21 times across 5 test files. One tests/gguf_emitter.h now defines them; identical host-order emit behavior. 46 tokenizer + 27 gguf + 29 writer tests pass; full suite 2929/2929.
The three rust/uncontrolled-allocation-size alerts master carries from PR #42 (StopTracker ring, draft/emit buffer capacities, partial top-k heap) each already had runtime filters, but the bounds were not visible to static analysis at the allocation site. Add inline min() clamps and a hard cap on the stop-sequence ring (4096); no behavior change for any realistic config.
Review findings on the new framework: - cr_skip_test longjmp'd with rc=2 but the child still exited 0, so skips were recorded as passes (platform-conditional tests silently counted as executed). Exit 77 from the skip path; synthesis now shows 'Skipped: 4' for the AVX-512-gated tests on non-AVX-512 hosts. - write_xml opened one <testsuite> per test but closed only one, producing malformed JUnit XML. Rewrite with per-suite grouping and per-test <testcase> rows (pass/fail/crash/skip); xmllint-clean.
The Criterion replacement still duplicated JUnit suites (~N² rows), counted skips as passes, treated waitpid failure as PASS, and treated flag-without-value as a silent empty filter. Restore the gemm decode serial threshold, keep llama RoPE positions as int64_t, and make the 4096 stop-sequence ring cap match only sequences that fit.

Name the QK-norm owner accurately.
OcLlamaConfig has no QK-norm field. The llama path stores QK-norm state in each OcLlamaLayer through attn_q_norm and attn_k_norm. The GLM-specific parsed flag is OcGlmConfig.apply_qk_norm. Update this parenthetical to name the correct type or types.

Clang AddressSanitizer __has_feature(address_sanitizer) __SANITIZE_ADDRESS__ predefined macro documentation
💡 Result:
To check for AddressSanitizer (ASan) support or activation in Clang, developers can use both the has_feature preprocessor macro and the SANITIZE_ADDRESS predefined macro. has_feature(address_sanitizer) The has_feature(address_sanitizer) macro is the traditional, idiomatic way to check if AddressSanitizer is enabled in Clang [1]. It evaluates to 1 if the AddressSanitizer feature is enabled for the current translation unit, and 0 otherwise [2][1]. It is standard practice to guard its use by first checking if the has_feature macro itself is supported [1]: #if defined(has_feature) # if has_feature(address_sanitizer) // Code that builds only when AddressSanitizer is enabled # endif #endif SANITIZE_ADDRESS The SANITIZE_ADDRESS macro is a predefined macro that is also set to 1 when AddressSanitizer is enabled [1][3]. While historically associated with GCC and MSVC [3][4], Clang has added support for this macro to improve cross-compiler compatibility and intends for it to be used alongside or as a eventual replacement for the has_feature check [1][4]. Usage and Best Practices When writing portable code (e.g., across Clang, GCC, and MSVC), it is recommended to check for both macros to ensure maximum compatibility [1][4]: #if has_feature(address_sanitizer) || defined(SANITIZE_ADDRESS) // Code that builds when AddressSanitizer is enabled #endif This approach ensures that your code correctly detects the sanitizer regardless of the specific compiler version or vendor implementation [1][4]. As Clang moves toward standardizing these macros, documentation suggests prioritizing this unified check to future-proof your codebase [1].

site:clang.llvm.org/docs AddressSanitizer __SANITIZE_ADDRESS__ __has_feature(address_sanitizer) Clang
💡 Result:
In Clang, you can detect if AddressSanitizer is enabled at compile time using either the has_feature(address_sanitizer) macro or the SANITIZE_ADDRESS preprocessor definition [1][2][3]. While has_feature(address_sanitizer) has been the standard approach in Clang for many years, it is considered deprecated [1][4][5]. Clang is transitioning to support SANITIZE_ADDRESS, which is also used by GCC, to provide a consistent cross-compiler interface for detecting sanitizer status [1][4][5]. For maximum compatibility, official documentation recommends checking for both [1][4][5]: #if has_feature(address_sanitizer) || defined(SANITIZE_ADDRESS) // AddressSanitizer is enabled #endif You can enable AddressSanitizer by compiling and linking your program with the -fsanitize=address flag [1]. If you need to disable instrumentation for specific functions, the recommended approach is to use the attribute((no_sanitize("address"))) attribute [1], often wrapped in a macro that checks for the availability of the sanitizer as shown above to ensure compatibility with other compilers [1][4][5].

Clang 18 __SANITIZE_ADDRESS__ -fsanitize=address predefined macro
💡 Result:
In Clang 18, the SANITIZE_ADDRESS predefined macro is not defined by the compiler by default, even when the AddressSanitizer is enabled via -fsanitize=address [1]. Historically, Clang has relied on the has_feature(address_sanitizer) preprocessor check to detect whether AddressSanitizer is active [1][2]. Because GCC automatically defines SANITIZE_ADDRESS when -fsanitize=address is used, many cross-platform codebases (such as the Linux kernel) have historically manually defined SANITIZE_ADDRESS themselves if has_feature(address_sanitizer) evaluated to true [3][4][1]. It is important to note that upstream Clang development has recently moved toward alignment with GCC in this regard. As of recent LLVM development (targeting Clang 22), support for automatically defining SANITIZE_ADDRESS and similar sanitizer macros has been introduced to the Clang frontend [5][3][6]. Because these macros are now being introduced natively in newer Clang versions, projects that previously implemented their own definitions must now ensure they only define these macros if they are not already defined by the compiler to avoid macro redefinition errors [4][6].

The CI runs Clang 18 with -fsanitize=address,undefined, but Clang 18 may not define __SANITIZE_ADDRESS__. The current branch can therefore install SIGSEGV and SIGABRT handlers that suppress ASan diagnostics. Also check __has_feature(address_sanitizer) before installing those handlers.

Fixed in 2b986a0. OC_TEST_ASAN is set from Clang __has_feature(address_sanitizer) as well as GCC __SANITIZE_ADDRESS__, and those SIGSEGV/SIGABRT handlers are not installed when either is set.

Reject invalid numeric option values.
atoi converts --verbose nope to 0, which silently selects quiet mode. It also cannot report overflow. Parse --jobs and --verbose with strtol, validate errno, endptr, and the supported range, then return 2 for invalid input.

Fixed in 2b986a0. --jobs and --verbose go through strtol (parse_nonneg_int); junk and overflow exit 2.

Preserve argument order for formatted assertion messages.
OC_ASSERT_OP and OC_EXPECT_OP pass caller arguments before the fixed %s operands. A call such as cr_assert_eq(a, b, "value=%d", value) can pass value to the first %s, causing undefined behavior during failure reporting. Pass the fixed operands before the caller’s format arguments through a helper.

Fixed in 2b986a0. OC_ASSERT_OP / OC_EXPECT_OP print the comparison operands via oc_test_fail_cmp / oc_test_soft_fail_cmp before the caller’s format args.

Clang 18 does not define __SANITIZE_ADDRESS__, so also gate child signal handlers on __has_feature(address_sanitizer). Parse --jobs and --verbose with strtol, print comparison operands before caller format args, and name QK-norm on OcLlamaLayer / OcGlmConfig instead of OcLlamaConfig.

When the filter is an existing bare case containing _, this per-test fallback still rewrites it for every nonmatching test. For example, the registry has many */config_init cases as well as config/init_defaults and config/init_null; --filter config_init (and TEST_FILTER=test_config_init) now runs all of them because the generated glob is config/init*, even though bare-case filtering should select only cases named config_init. This makes targeted runs execute unrelated tests and potentially fail for unrelated reasons; determine whether an exact case or suite exists before enabling the underscore rewrite, or require an explicit slash for this ambiguity.
Useful? React with 👍 / 👎.

Valid. 79bd793 only rewrites _ → / when the slash-less filter does not already name a suite or case, so --filter config_init stays on */config_init and does not glob config/init*. kv_cache_init / gguf_v3_header still rewrite when there is no exact hit. Covered in test_framework.c.
A slash-less filter that already names a suite or case (config_init) must not also glob config/init*. Underscore rewrite stays for Makefile TEST_FILTER names like kv_cache_init when no exact match exists. --list now honours --filter; a failed --xml write exits 1.
