| | | | | | | | Robust assert about all data ops are schedulable. Utiltiies for several places domionator-like stuff is used. Removing a Phi with matching null/not-null values is now more robust; removes a major source if scheduling misalignment. Big comments about what gets covered by a null check, or not.

| * Fix stale copy-pasted comment on BoolNode's phiCon call (#249)Symious2026-09-091-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The three comment lines above `AddNode.phiCon(this, ...)` in BoolNode were copy-pasted from MulNode and never adapted: they use `*` as the operator and describe the rotated shape `(x * (phi cons)) * con`. For BoolNode neither is right. The operator is a compare, and in chapters 6-9 `rotate` is hard-coded `false`, so the rotated shape is never matched; the shapes actually handled are `(phi cons) cmp con` and `(phi cons) cmp (phi cons)`. Reword the comment accordingly, and in chapters 6-9 add a line noting why rotate is off. Chapters 10-25 pass `this instanceof EQ`, so no such claim is made there. Comment-only change; no code is touched. Co-authored-by: Claude Opus 5 <noreply@anthropic.com>

Introduce Chapter 25 with separately compiled Simple modules, serialized IR, cross-compilation-unit linking, and native system-library integration. This also completes a broad parser and type-system cleanup needed to make graph construction independent of incomplete parse-time type information. Separate compilation and linking - Add compilation-unit Start/Stop nodes and track functions, classes, aliases, and global indices across compilation-unit boundaries. - Serialize canonical types and ideal graph nodes into ELF objects, including dependency metadata, relocations, global/local bitset remapping, and dense memory-alias information. - Load dependent objects on demand, recursively resolve source and object paths, relink calls and function pointers, and preserve external C symbols. - Distinguish the post-optimization ownership hook from unknown callers so private call graphs can remain precise while public functions remain externally callable. - Add command-line and build support for compiling modules and the reusable `sys` object library. Parser, constructors, and SSA - Replace inline constructor expansion with a hidden default `<init>` followed by an explicit user constructor declared as `new Type = { ... }`. - Keep the default constructor private, pass private object memory through constructor calls, and require user constructors to initialize non-default fields before the object escapes. - Track possibly-uninitialized fields in parser `Var` state and diagnose early reads without encoding parser-only constraints in Load and Store nodes. - Make ordinary parser memory bulk and recover precise alias slices in the optimizer using `MemMerge`, `MemPhi`, and `BulkMemPhi` nodes. - Remove parser-supplied type constraints from Loads and ordinary Phis, defer integer/float arithmetic selection, and keep call shape driven by syntax instead of provisional inferred types. - Preserve chained field declarations as static parser information when flow types are not yet available, including postfix field updates through calls. Types, functions, and escape analysis - Add `TypeScalar` as the common lattice family for integer, float, memory pointer, and function-pointer values, with scalar TOP/BOT values for generic Loads, Stores, parameters, and invalid intermediate expressions. - Represent unresolved struct definitions directly with the `TypeStruct` forward-reference flag while retaining the separate open-structure concept; close and canonicalize recursive structures without side maps. - Add explicit `FunPtrNode` references so constant function pointers retain a graph edge to their Return, and keep referenced functions alive until Opto proves the pointer dead. - Refine public-function and class-initializer escape handling, including public-only fallback escape sets and monotone compilation-unit summaries. - Add guards, proof casts, read-only propagation, pointer-to-integer conversion for non-null FFI arguments, and consistent deep mutability checks at calls. Optimization and code generation - Make weak and unresolved graph inputs compute conservatively and monotonically throughout iterative peepholes and SCCP. - Preserve independent memory slices when sharpening Stores, retain control on conditional Stores, and freeze Store widths from their target field types. - Extend serialization for new node kinds, scalar types, Store modes, function pointers, and memory partitions, preserving serialize/deserialize bijection. - Complete native selection and encoding support across x86-64, RISC-V, and ARM, including FFI pointer conversion and missing integer operations. - Fix x86 immediate multiply REX encoding and assorted scheduling, register allocation, spilling, relocation, and constant-pool issues exposed by the larger linked graphs. System library, tests, and documentation - Compile and link the Simple `sys` library, including libc bindings, I/O, scanners, strings, vectors, array helpers, and executable entry points. - Add Chapter 25 module, serialization, constructor, forward-reference, postfix-update, system, Hello World, and Bubble Sort coverage; update golden graphs and spill expectations for the new IR shape. - Add module and type-system documentation, parser-simplification design notes, grammar updates, examples, diagrams, and graph visualization assets. The resulting compiler passes the raw Chapter 1-24 suite and the Chapter 25 system and separate-compilation tests, including a freshly rebuilt `sys.o` and the native Bubble Sort example.
