* New evaluator, more Compiler Driver cleanupCliff Click2025-01-1552-619/+1073
| | | | | | | | | | More compiler driver cleanup: Stop only has Return inputs, never an expr. Drop extra lexical scope. Linker table moves to CodeGen. Replace evaluator with a simpler design; I was unable to get the current design to work with the other changes. Updates to old eval; proper idoms; forced type checks; extensions for Fun, Return, Call, CallEnd. Accessor find next control to execute. Accessor for deciding when its ok to optimize a Function/Return, Call/CallEnd, Stop, ScopeMin (merge) Add local scheduling pass. IRPrinter uses SB instead of StringBuilder Spelling SubF comment

* Cleanup compile driverCliff Click2025-01-1559-1179/+1693
| | | | | | | | | | Top level makes a "main" function and calls it. Opto() pass inlines main into top-level and removes the function call. If peeps are off, the function call remains; this breaks many tests. Add a FunNode function header; Return is its end. Return no long used at the top level; only a single return per-function, merging all returns (breaks many tests). Add a Call & CallEnd nodes. Fix many tests to pass again. Fix a bunch of minor bugs.

* All parsing null to be TFP or TMPCliff Click2025-01-1551-429/+1606
| | | | | | | | Insert a TypePtr/TypeNil around TypeMemPtr and TypeFunPtr in the lattice; allows the parsing of "null" to mean either a TMP or TFP null. Cleanup Type null checks and several prints. Drop Type.lub, Type.makeInit. Add a Parser NIL & ZERO. Clean up parser errors, track line numbers for future parser errors.
* Add a tighter/graphviz-oriented type printCliff Click2025-01-158-4/+37

* viewer improvementsCliff Click2025-01-153-27/+57
| | | | | | | viewer highlights parsed text; larger input box removes some double-display handles mouse over-run
* Greatly improved JSViewerCliff Click2025-01-1525-212/+210
| | | | | | | | | | Handle memory edges. Color-coded edges & nodes to match lattice. Add SB vs StringBuilder. JSViewer needs SB to keep my sanity. Catch successful peeps and `show` them. Drop unused LLVM format, so I don't need to support Yet Another Printer. SimpleWebSocket handles longer packets; more robust close. Bug fix st/new fold. Bug fix Phi pull-down op losing precision.
* Progress JSViewCliff Click2025-01-1512-73/+446

* Final? pass of finalsCliff Click2024-11-2326-215/+426
| | | | | | | Add a least-upper-bound to set Phis to their respective Top while preserving final fields. Requires a ReadOnly node to "cast-away-writable". Series of isFinal/makeRO in all Types. Changes tests to match r/w intent.

* Much more robust guarded expression upcastingCliff Click2024-11-2317-122/+187
| | | | | Region does not print id, making all test cases much more stable (and slightly weaker). NotNode gets more precise compute
* Change field mutabilityCliff Click2024-11-2319-95/+365
| | | | | | | | Fields & locals with an initializer are immutable by default; those without are mutable. Make mutable with `!`. Fields are always mutable in a constructor. Add a trinary `pred ? then : else` syntax. SubNode retains as much precision as AddNode. Sharpen some asserts and error cases. Limit Load node cloning if the ptr is not obvious.

| | | | | | | | | | Fix eval auto-string result. Fix tests hacked because of this. Turn on BrainFuck in ch15,16,17, also disabled because of this. Use new features in BrainFuck. Fix bug not lifting forward refs; add a toString to Vars. Fix some missing addDeps. Remove large complex not-productive peep. Upcast after "while" tests. Improves a bunch of tests. Remove dead getBlockStart.
