From 00ff8425ba806e4781fc68f51ded8874a418ae1b Mon Sep 17 00:00:00 2001 From: "John C. Burnham" Date: Wed, 14 Jan 2026 06:55:03 -0500 Subject: [PATCH 01/32] WIP: Ixon serialization rewrite with 85% size reduction Major rewrite of the Ixon serialization format optimized for space efficiency. Now Ix + Lean in Lean environment compiles in 10.21 seconds with serialized size of 1.6 GB Key changes: - Split ixon module into separate files (constant, env, expr, univ, metadata, serialize, sharing, tag, comm, error) - New tag-based encoding (Tag0, Tag2, Tag4) for compact representation - Refs table: deduplicates constant references using indices instead of inline 32-byte addresses - Univs table: deduplicates universe terms per constant - Global name indexing: shares names across entire environment, metadata uses u64 indices instead of 32-byte addresses - Sharing analysis: identifies shared subexpressions within constants - Pre-order traversal indexing for expression metadata The old ixon module preserved as ixon_old.rs for migration reference. --- src/ix.rs | 1 + src/ix/address.rs | 3 + src/ix/compile.rs | 4559 ++++++++++++++++++++++++++++---------- src/ix/decompile.rs | 1822 ++++++++------- src/ix/env.rs | 3 +- src/ix/ixon.rs | 2462 +------------------- src/ix/ixon/comm.rs | 73 + src/ix/ixon/constant.rs | 385 ++++ src/ix/ixon/env.rs | 193 ++ src/ix/ixon/error.rs | 148 ++ src/ix/ixon/expr.rs | 327 +++ src/ix/ixon/metadata.rs | 595 +++++ src/ix/ixon/serialize.rs | 1452 ++++++++++++ src/ix/ixon/sharing.rs | 710 ++++++ src/ix/ixon/tag.rs | 567 +++++ src/ix/ixon/univ.rs | 237 ++ src/ix/ixon_old.rs | 2431 ++++++++++++++++++++ src/ix/mutual.rs | 20 +- src/lean/ffi/ixon.rs | 2 +- src/lean/ffi/lean_env.rs | 18 + src/lean/nat.rs | 12 + 21 files changed, 11514 insertions(+), 4506 deletions(-) create mode 100644 src/ix/ixon/comm.rs create mode 100644 src/ix/ixon/constant.rs create mode 100644 src/ix/ixon/env.rs create mode 100644 src/ix/ixon/error.rs create mode 100644 src/ix/ixon/expr.rs create mode 100644 src/ix/ixon/metadata.rs create mode 100644 src/ix/ixon/serialize.rs create mode 100644 src/ix/ixon/sharing.rs create mode 100644 src/ix/ixon/tag.rs create mode 100644 src/ix/ixon/univ.rs create mode 100644 src/ix/ixon_old.rs diff --git a/src/ix.rs b/src/ix.rs index 25906b8e..208bfd19 100644 --- a/src/ix.rs +++ b/src/ix.rs @@ -6,6 +6,7 @@ pub mod env; pub mod graph; pub mod ground; pub mod ixon; +pub mod ixon_old; // Temporary: old ixon module for migration pub mod mutual; pub mod store; pub mod strong_ordering; diff --git a/src/ix/address.rs b/src/ix/address.rs index 1a61e2c8..05db8359 100644 --- a/src/ix/address.rs +++ b/src/ix/address.rs @@ -12,6 +12,9 @@ impl Address { pub fn from_slice(input: &[u8]) -> Result { Ok(Address { hash: Hash::from_slice(input)? }) } + pub fn from_blake3_hash(hash: Hash) -> Self { + Address { hash } + } pub fn hash(input: &[u8]) -> Self { Address { hash: blake3::hash(input) } } diff --git a/src/ix/compile.rs b/src/ix/compile.rs index 382fb417..ace9c670 100644 --- a/src/ix/compile.rs +++ b/src/ix/compile.rs @@ -1,1039 +1,1437 @@ +//!

From 745f39a7caf78c702b34257757a87c326cc70cd0 Mon Sep 17 00:00:00 2001 From: "John C. Burnham" Date: Thu, 15 Jan 2026 14:49:36 -0500 Subject: [PATCH 05/32] Fix sharing vector topological ordering and hash-consed size calculation Main fix: build_sharing_vec now re-sorts shared hashes in topological order (leaves first) instead of using gross-benefit order from decide_sharing. Previously, large compound expressions came first and couldn't reference their children via Share(idx), causing each entry to inline entire subtrees (30-35KB per entry instead of 3-13 bytes). This caused 1140x blow-up for pathological blocks like denote_blastDivSubtractShift_q. Also fixes hash-consed size calculation to include structural overhead for Inductive/Constructor/Recursor data structures, not just expressions. This makes the comparison fair - previously simple enums like SymbolKind showed Ixon as worse than hash-consing (1.91x) when it's actually 21x better. Results after fix: - Overall ratio: 0.071x (Ixon is 14x more efficient than hash-consing) - 0 blocks with ratio >= 1.0x (previously 4) - 11,722 blocks with 20x+ compression - Total serialized: 159MB vs 2.24GB hash-consed Other changes: - Remove early-break bug in decide_sharing that skipped profitable candidates - Add TRACK_HASH_CONSED_SIZE and ANALYZE_SHARING debug flags - Add analyze_sharing_stats() for debugging pathological cases - Add test_early_break_bug unit test - Add granular ratio distribution buckets in size analysis output --- src/ix/compile.rs | 155 +++++++++++++++-- src/ix/ixon/sharing.rs | 355 +++++++++++++++++++++++++++++++-------- src/lean/ffi/lean_env.rs | 69 +++++--- 3 files changed, 466 insertions(+), 113 deletions(-) diff --git a/src/ix/compile.rs b/src/ix/compile.rs index 0f702aed..5caf7a6a 100644 --- a/src/ix/compile.rs +++ b/src/ix/compile.rs @@ -47,6 +47,17 @@ use crate::{ lean::nat::Nat, }; +/// Whether to track hash-consed sizes during compilation. +/// This adds overhead to sharing analysis and can be disabled for production. +/// Set to `true` to enable hash-consed vs serialized size comparison. +pub static TRACK_HASH_CONSED_SIZE: std::sync::atomic::AtomicBool = + std::sync::atomic::AtomicBool::new(false); + +/// Whether to output verbose sharing analysis for pathological blocks. +/// Set via IX_ANALYZE_SHARING=1 environment variable. +pub static ANALYZE_SHARING: std::sync::atomic::AtomicBool = + std::sync::atomic::AtomicBool::new(false); + /// Size statistics for a compiled block. #[derive(Clone, Debug, Default)] pub struct BlockSizeStats { @@ -648,12 +659,32 @@ fn compute_hash_consed_size( /// Apply sharing analysis to a set of expressions. /// Returns the rewritten expressions, sharing vector, and hash-consed size. -fn apply_sharing_with_stats(exprs: Vec>) -> SharingResult { - let (info_map, ptr_to_hash) = analyze_block(&exprs); +/// +/// Hash-consed size tracking is controlled by the global `TRACK_HASH_CONSED_SIZE` flag. +fn apply_sharing_with_stats(exprs: Vec>, block_name: Option<&str>) -> SharingResult { + let track = TRACK_HASH_CONSED_SIZE.load(AtomicOrdering::Relaxed); + let analyze = ANALYZE_SHARING.load(AtomicOrdering::Relaxed); + let (info_map, ptr_to_hash) = analyze_block(&exprs, track); - // Compute hash-consed size (always computed, even if no sharing) + // Compute hash-consed size (sum from info_map, which is 0 if tracking disabled) let hash_consed_size = compute_hash_consed_size(&info_map); + // Output detailed analysis if requested and this is a large block + // Use threshold to catch pathological cases + if analyze && info_map.len() > 5000 { + let name = block_name.unwrap_or(""); + let stats = sharing::analyze_sharing_stats(&info_map); + eprintln!( + "\n=== Sharing analysis for block {:?} with {} unique subterms ===", + name, info_map.len() + ); + eprintln!("{}", stats); + eprintln!( + "hash_consed_size from analysis: {} bytes (tracking={})", + hash_consed_size, track + ); + } + // Early exit if no sharing opportunities (< 2 repeated subterms) let has_candidates = info_map.values().any(|info| info.usage_count >= 2); if !has_candidates { @@ -676,7 +707,7 @@ fn apply_sharing_with_stats(exprs: Vec>) -> SharingResult { /// Returns the rewritten expressions and the sharing vector. #[cfg(test)] fn apply_sharing(exprs: Vec>) -> (Vec>, Vec>) { - let result = apply_sharing_with_stats(exprs); + let result = apply_sharing_with_stats(exprs, None); (result.rewritten, result.sharing) } @@ -694,8 +725,9 @@ fn apply_sharing_to_definition_with_stats( def: Definition, refs: Vec

Burnham" Date: Thu, 29 Jan 2026 22:56:13 -0500 Subject: [PATCH 09/32] Add pure Lean compiler (CompileM) with cross-implementation verification, refactor FFI layer into focused modules, and migrate pipeline to Ix types Introduce a pure Lean compiler (CompileM) that produces bit-identical Ixon output to the existing Rust compiler, enabling cross-implementation verification. The compiler supports both sequential and wave-based parallel compilation with optional fail-fast mismatch detection against the Rust reference implementation. Lean-side additions: - Ix/CompileM.lean: ~2000-line pure Lean compiler with reader/state/except monad stack. Supports parallel compilation via wave-based scheduling with dedicated worker threads and channels. - Ix/DecompileV2.lean: Decompiler from Ixon format back to Lean expressions, resolving refs/univs tables and expanding sharing references. - Ix/ShardMap.lean: Concurrent hashmap with power-of-2 sharding, cache-line padding, double-checked locking, and bulk insert parallelism. - Ix/Sharing.lean: Pure Lean sharing analysis using alpha-invariant Merkle-tree hashing (blake3). Two-phase O(n) algorithm with DAG construction via post-order traversal and profitability heuristic. Lean-side migrations: - GraphM, CondenseM, Mutual: migrated from Lean.Name/Lean.Expr to Ix.Name/Ix.Expr throughout the compilation pipeline. - Ix/Ixon.lean: expanded with metadata types (ExprMetaData, ExprMetaArena, ConstantMeta, Named, Comm), full serialization for metadata, and array-based RawEnv types for FFI boundaries. - MutCtx definition moved from Common.lean to Environment.lean. Rust-side refactoring: - Split monolithic src/lean/ffi/ixon.rs (1959 lines) into ixon/ module with focused files: compare, constant, enums, env, expr, meta, serialize, sharing, univ. - Split src/lean/ffi/lean_env_builder.rs (2551 lines) into builder.rs, compile.rs, graph.rs, and ix/ submodule (address, constant, data, env, expr, level, name). - Added primitives.rs for basic Lean type FFI roundtrips. - Preserved legacy FFI in ixon_legacy.rs. - Updated compile.rs and decompile.rs for new metadata and canonicalization pipeline. Test infrastructure: - Reorganized test generators into Tests/Gen/{Basic,Ix,Ixon}.lean. - Reorganized FFI tests into Tests/FFI/{Basic,Ix,Ixon}.lean. - Added property-based roundtrip tests for all FFI types using SlimCheck. - Added cross-implementation serialization comparison tests (Lean vs Rust byte-level equality for univs, exprs, constants, and envs). - New domain tests: Tests/Ix/{CondenseM,GraphM,Sharing}.lean, Tests/ShardMap.lean. - Removed obsolete Tests/FFIConsistency.lean. Key design decisions: - Arena-based expression metadata separates semantic content (alpha-invariant constants) from non-semantic metadata (binder names, reducibility hints). - Array-based "Raw" types bridge the FFI boundary, avoiding hash function mismatches between Lean and Rust. - All serialized sections sorted by address for deterministic output. - Name indices use DFS topological sort with address-based tie-breaking. --- Benchmarks/ShardMap.lean | 351 ++++ Ix/Common.lean | 8 +- Ix/CompileM.lean | 1965 +++++++++++++++++++++++ Ix/CondenseM.lean | 130 +- Ix/DecompileV2.lean | 399 +++++ Ix/Environment.lean | 28 +- Ix/GraphM.lean | 120 +- Ix/Ixon.lean | 801 +++++++++- Ix/Mutual.lean | 99 +- Ix/ShardMap.lean | 446 ++++++ Ix/Sharing.lean | 510 ++++++ Tests.lean | 11 + Tests/Common.lean | 33 +- Tests/FFI.lean | 15 + Tests/FFI/Basic.lean | 134 ++ Tests/FFI/Ix.lean | 270 ++++ Tests/FFI/Ixon.lean | 304 ++++ Tests/FFIConsistency.lean | 31 - Tests/Gen/Basic.lean | 182 +++ Tests/Gen/Ix.lean | 584 +++++++ Tests/Gen/Ixon.lean | 456 ++++++ Tests/Ix.lean | 209 --- Tests/Ix/Compile.lean | 1413 ++++++----------- Tests/Ix/CondenseM.lean | 383 +++++ Tests/Ix/FFI.lean | 1644 ++++++++++++++----- Tests/Ix/GraphM.lean | 469 ++++++ Tests/Ix/Ixon.lean | 722 ++------- Tests/Ix/Sharing.lean | 1182 ++++++++++++++ Tests/Main.lean | 99 +- Tests/ShardMap.lean | 430 +++++ c/rust.h | 50 + src/ix/compile.rs | 346 ++-- src/ix/decompile.rs | 943 +++++++---- src/ix/env.rs | 2 +- src/ix/graph.rs | 7 +- src/ix/ixon.rs | 2 +- src/ix/ixon/metadata.rs | 450 +++--- src/ix/ixon/serialize.rs | 20 +- src/ix/ixon/sharing.rs | 70 +- src/ix/mutual.rs | 7 +- src/lean/ffi/builder.rs | 40 + src/lean/ffi/compile.rs | 557 +++++++ src/lean/ffi/graph.rs | 120 ++ src/lean/ffi/ix/address.rs | 39 + src/lean/ffi/ix/constant.rs | 521 ++++++ src/lean/ffi/ix/data.rs | 495 ++++++ src/lean/ffi/ix/env.rs | 277 ++++ src/lean/ffi/ix/expr.rs | 419 +++++ src/lean/ffi/ix/level.rs | 150 ++ src/lean/ffi/ix/mod.rs | 26 + src/lean/ffi/ix/name.rs | 127 ++ src/lean/ffi/ixon.rs | 1959 ----------------------- src/lean/ffi/ixon/compare.rs | 206 +++ src/lean/ffi/ixon/constant.rs | 777 +++++++++ src/lean/ffi/ixon/enums.rs | 111 ++ src/lean/ffi/ixon/env.rs | 282 ++++ src/lean/ffi/ixon/expr.rs | 274 ++++ src/lean/ffi/ixon/meta.rs | 638 ++++++++ src/lean/ffi/ixon/mod.rs | 24 + src/lean/ffi/ixon/serialize.rs | 724 +++++++++ src/lean/ffi/ixon/sharing.rs | 52 + src/lean/ffi/ixon/univ.rs | 120 ++ src/lean/ffi/ixon_legacy.rs | 626 ++++++++ src/lean/ffi/lean_env.rs | 80 + src/lean/ffi/lean_env_builder.rs | 2551 ------------------------------ src/lean/ffi/mod.rs | 11 +- src/lean/ffi/primitives.rs | 424 +++++ src/lean/mod.rs | 16 + 68 files changed, 19225 insertions(+), 7746 deletions(-) create mode 100644 Benchmarks/ShardMap.lean create mode 100644 Ix/CompileM.lean create mode 100644 Ix/DecompileV2.lean create mode 100644 Ix/ShardMap.lean create mode 100644 Ix/Sharing.lean create mode 100644 Tests.lean create mode 100644 Tests/FFI.lean create mode 100644 Tests/FFI/Basic.lean create mode 100644 Tests/FFI/Ix.lean create mode 100644 Tests/FFI/Ixon.lean delete mode 100644 Tests/FFIConsistency.lean create mode 100644 Tests/Gen/Basic.lean create mode 100644 Tests/Gen/Ix.lean create mode 100644 Tests/Gen/Ixon.lean create mode 100644 Tests/Ix/CondenseM.lean create mode 100644 Tests/Ix/GraphM.lean create mode 100644 Tests/Ix/Sharing.lean create mode 100644 Tests/ShardMap.lean create mode 100644 src/lean/ffi/builder.rs create mode 100644 src/lean/ffi/compile.rs create mode 100644 src/lean/ffi/graph.rs create mode 100644 src/lean/ffi/ix/address.rs create mode 100644 src/lean/ffi/ix/constant.rs create mode 100644 src/lean/ffi/ix/data.rs create mode 100644 src/lean/ffi/ix/env.rs create mode 100644 src/lean/ffi/ix/expr.rs create mode 100644 src/lean/ffi/ix/level.rs create mode 100644 src/lean/ffi/ix/mod.rs create mode 100644 src/lean/ffi/ix/name.rs delete mode 100644 src/lean/ffi/ixon.rs create mode 100644 src/lean/ffi/ixon/compare.rs create mode 100644 src/lean/ffi/ixon/constant.rs create mode 100644 src/lean/ffi/ixon/enums.rs create mode 100644 src/lean/ffi/ixon/env.rs create mode 100644 src/lean/ffi/ixon/expr.rs create mode 100644 src/lean/ffi/ixon/meta.rs create mode 100644 src/lean/ffi/ixon/mod.rs create mode 100644 src/lean/ffi/ixon/serialize.rs create mode 100644 src/lean/ffi/ixon/sharing.rs create mode 100644 src/lean/ffi/ixon/univ.rs create mode 100644 src/lean/ffi/ixon_legacy.rs delete mode 100644 src/lean/ffi/lean_env_builder.rs create mode 100644 src/lean/ffi/primitives.rs diff --git a/Benchmarks/ShardMap.lean b/Benchmarks/ShardMap.lean new file mode 100644 index 00000000..37cec826 --- /dev/null +++ b/Benchmarks/ShardMap.lean @@ -0,0 +1,351 @@ +import Ix.ShardMap +import Ix.Benchmark.Bench + +open Ix + +namespace Benchmarks.ShardMap + +/-!

Burnham" Date: Mon, 2 Feb 2026 17:23:12 -0500 Subject: [PATCH 12/32] Activate pure Lean decompiler with metadata support and roundtrip test Rewrite DecompileM to decompile Ixon format to Ix types (not Lean types), enabling cheap Blake3 hash comparison for roundtrip verification. Add arena-based metadata restoration (binder names, binder info, mdata), Syntax/DataValue blob deserialization, and chunked parallel decompilation. Extend Rust FFI to pass the full names table (1.3M entries including binder names and level params) through RawEnv, fixing lookup failures for non-constant-name addresses. Add standalone `lake test -- decompile` suite: 187K constants roundtrip with 0 errors and 0 mismatches. --- Ix/CompileM.lean | 9 +- Ix/DecompileM.lean | 1052 ++++++++++++++++++++++++++------------ Ix/Ixon.lean | 8 + Tests/Gen/Ixon.lean | 5 + Tests/Ix/Compile.lean | 1 + Tests/Ix/Decompile.lean | 128 +++++ Tests/Main.lean | 2 + src/lean/ffi/compile.rs | 34 +- src/lean/ffi/ixon/env.rs | 50 +- 9 files changed, 954 insertions(+), 335 deletions(-) create mode 100644 Tests/Ix/Decompile.lean diff --git a/Ix/CompileM.lean b/Ix/CompileM.lean index 3d048283..bafd220f 100644 --- a/Ix/CompileM.lean +++ b/Ix/CompileM.lean @@ -1935,8 +1935,11 @@ def rsCompilePhases (leanEnv : Lean.Environment) : IO CompilePhases := do let mut compileEnv : Ixon.Env := {} for ⟨addr, const⟩ in raw.compileEnv.consts do compileEnv := compileEnv.storeConst addr const + -- Load the full names table from Rust (includes binder names, level params, etc.) + for ⟨addr, name⟩ in raw.compileEnv.names do + compileEnv := { compileEnv with names := compileEnv.names.insert addr name } for ⟨name, addr, constMeta⟩ in raw.compileEnv.named do - -- Add all name components to the names map (for indexed serialization) + -- Also add name components for indexed serialization compileEnv := { compileEnv with names := Ixon.RawEnv.addNameComponents compileEnv.names name } compileEnv := compileEnv.registerName name ⟨addr, constMeta⟩ for ⟨addr, bytes⟩ in raw.compileEnv.blobs do @@ -1954,7 +1957,11 @@ def rsCompileEnv (leanEnv : Lean.Environment) : IO Ixon.Env := do let mut env : Ixon.Env := {} for ⟨addr, const⟩ in rawEnv.consts do env := env.storeConst addr const + -- Load the full names table from Rust + for ⟨addr, name⟩ in rawEnv.names do + env := { env with names := env.names.insert addr name } for ⟨name, addr, constMeta⟩ in rawEnv.named do + env := { env with names := Ixon.RawEnv.addNameComponents env.names name } env := env.registerName name ⟨addr, constMeta⟩ for ⟨addr, bytes⟩ in rawEnv.blobs do env := { env with blobs := env.blobs.insert addr bytes } diff --git a/Ix/DecompileM.lean b/Ix/DecompileM.lean index 8e77fc28..7c08dce0 100644 --- a/Ix/DecompileM.lean +++ b/Ix/DecompileM.lean @@ -1,34 +1,38 @@ /- - DecompileM: Decompilation from the new Ixon format to Lean. + DecompileM: Decompilation from the Ixon format to Ix types. - This module decompiles the new Ixon format (with indirection tables and sharing) - back to Lean expressions and constants.

Burnham" Date: Mon, 2 Feb 2026 23:41:24 -0500 Subject: [PATCH 14/32] Align Lean/Rust error types for FFI, add Rust serialize and decompile endpoints MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Unify CompileError, DecompileError, and SerializeError across Lean and Rust so constructor tag order matches exactly, enabling direct FFI roundtripping. Replace catch-all MissingName variant with specific error types (BadConstantFormat, BlobNotFound, BadBlobFormat). Change CompileError fields from Name/Expr to String for FFI compatibility and add UnknownUnivParam variant. Add new Rust FFI endpoints: rs_ser_env/rs_des_env for Ixon.Env serialization, and rs_decompile_env for full decompilation. Consolidate duplicated RawEnv→Env conversion into RawEnv.toEnv, include full names table for round-trip fidelity. Add roundtrip tests for all three error types (unit + property-based) and integration tests for Rust serialization and decompilation pipelines. --- Ix.lean | 1 + Ix/CompileM.lean | 102 +++----- Ix/DecompileM.lean | 56 +++-- Ix/Ixon.lean | 71 +++++- Tests/FFI/Ix.lean | 54 +++++ Tests/Gen/Ix.lean | 81 +++++++ Tests/Ix/RustDecompile.lean | 126 ++++++++++ Tests/Ix/RustSerialize.lean | 99 ++++++++ Tests/Main.lean | 4 + c/ixon_ffi.c | 8 + src/ix/compile.rs | 26 +- src/ix/decompile.rs | 32 +-- src/ix/ixon/error.rs | 87 ++++--- src/ix/ixon/expr.rs | 1 - src/lean/ffi/compile.rs | 468 +++++++++++++++++++++++++++++++++++- src/lean/ffi/ixon/env.rs | 137 ++++++++++- src/lean/mod.rs | 8 + 17 files changed, 1191 insertions(+), 170 deletions(-) create mode 100644 Tests/Ix/RustDecompile.lean create mode 100644 Tests/Ix/RustSerialize.lean diff --git a/Ix.lean b/Ix.lean index ae8d2e94..7100585c 100644 --- a/Ix.lean +++ b/Ix.lean @@ -8,4 +8,5 @@ import Ix.Meta import Ix.GraphM import Ix.CondenseM import Ix.CompileM +import Ix.DecompileM import Ix.Benchmark.Bench diff --git a/Ix/CompileM.lean b/Ix/CompileM.lean index bafd220f..3cdcaf90 100644 --- a/Ix/CompileM.lean +++ b/Ix/CompileM.lean @@ -117,24 +117,24 @@ structure BlockEnv where /-! ## Compilation Error -/ -/-- Compilation error type. -/ +/-- Compilation error type.

Burnham" Date: Tue, 3 Feb 2026 19:09:28 -0500 Subject: [PATCH 17/32] Track all name components during Lean compilation to match Rust The Lean compiler's `storeNameStrings` only stored string blobs but never populated a names map during compilation. Names were derived solely from `named` entries at aggregation time, producing ~239K names vs Rust's ~1.3M (which tracks every name encountered during compilation). Replace `storeNameStrings` with `compileName` that both stores string blobs and records each name component in a new `BlockState.blockNames` map. Add missing `compileName` calls for binder names, level params, MData keys, DataValue names, Syntax node kinds, ident values, and preresolved namespace/decl names. Merge per-block names during aggregation in both sequential and parallel compilation paths. Also fix `SerializeError.toString` to use `String.ofList` instead of the removed `List.asString`. --- Ix/CompileM.lean | 131 ++++++++++++++++++++++++++++++----------------- Ix/Ixon.lean | 2 +- 2 files changed, 86 insertions(+), 47 deletions(-) diff --git a/Ix/CompileM.lean b/Ix/CompileM.lean index 3cdcaf90..02b9afdc 100644 --- a/Ix/CompileM.lean +++ b/Ix/CompileM.lean @@ -78,6 +78,8 @@ structure BlockState where univsIndex : Std.HashMap Ixon.Univ UInt64 := {} /-- Blob storage collected during block compilation -/ blockBlobs : Std.HashMap Address ByteArray := {} + /-- Name components collected during block compilation -/ + blockNames : Std.HashMap Address Ix.Name := {} /-- Arena-based expression metadata for the current constant -/ arena : Ixon.ExprMetaArena := {} deriving Inhabited @@ -304,16 +306,26 @@ def storeString (s : String) : CompileM Address := do modifyBlockState fun c => { c with blockBlobs := c.blockBlobs.insert addr bytes } pure addr -/-- Store all string components of a name as blobs for deduplication. +/-- Compile a name: store all string components as blobs and track + name components in blockNames for deduplication.

Only push one representative per equivalence class into Muts array, matching the class-based indexing used by MutConst::ctx and projections. Previously, all constants were pushed flat, causing index misalignment when an equivalence class had >1 member. Fixed on both Rust and Lean sides. - Fix compare_const cross-kind ordering to use MutConstKind discriminant instead of always returning Lt. - Fix compare_const/compare_ctor cache key inversion by tracking swap state. - Fix check_decompile to return Err on mismatches instead of always Ok. - Fix CString::new().unwrap() panics by adding safe_cstring helper that filters null bytes instead of panicking. - Fix Box::leak memory leaks in decode_serialize_error by changing SerializeError fields from &'static str to String. - Fix buildSharingVec call sites in Tests/Ix/Sharing.lean after removing unused _topoOrder parameter. Performance: - Replace busy-wait polling (sleep 100us) with Condvar in compile_env work-stealing loop. - Eliminate double serialization in Lean compilation by adding blockBytes and blockAddr to BlockResult, computed once via BlockResult.mk'. - Deduplicate DefnInfo/ThmInfo/OpaqueInfo compilation into compile_single_def helper. Cleanup: - Remove debug leftovers: BLE' dbg_trace filter, ~90 lines of commented-out code in Common.lean, unused progress tracking variables. - Remove unused _topoOrder parameter from buildSharingVec (Lean). - Deduplicate u64ByteCount by referencing Ixon.u64ByteCount in CompileM. - Guard division by zero in SharingStats::Display. - Improve put_idx panic message with index size context. - Fix doc comment typo: Bytes1 -> Bytes2 in bytes2.rs.
