The blaise compiler now compiles its own source (tests/blaise-compiler.pas) into a second-stage binary that successfully compiles and runs a hello-world program. All 834 compiler tests still pass. Codegen and RTL fixes that unblocked self-hosting: - String literal interning (uCodeGenQBE): set FStrLits.CaseSensitive := True. FPC's TStringList.IndexOf is case-insensitive by default, so distinct literals like 'WRITELN' and 'WriteLn' collapsed to the same label. - ARC on implicit Self.Field assignments (uCodeGenQBE): EmitAssignment's implicit-Self branch did a raw storel for class/string fields. Fresh _ClassAlloc'ed objects start at refcnt 0, so without the addref they were freed by later local releases. Now addrefs new value and releases old. - #nn character literals (uLexer): UnescapeString handled only 'text'. Extended to decode #nn decimal literals and concatenated forms like 'abc'#13#10'def'. Local OrdAt helper lets the body parse under FPC and the self-hosted compiler. - Chr() builtin: registered in uSymbolTable, handled in uSemantic, emitted in uCodeGenQBE as _Chr, implemented in rtl/blaise_str.c. - LF line separator (Classes.pas): TStringList.GetText used #13#10; QBE rejects CR in its input. Changed to #10. Self-hosting source (tests/blaise-compiler.pas) — needs a virtual Destroy on TASTNode and Exception (post-TObject-stripping they became root classes without a vtable, breaking `is` checks and exception message layout). TAST* descendants chain `override`. Migration tooling: add tools/migrate_full.py — the script that generates tests/blaise-compiler.pas by flattening the eight compiler units and RTL Classes unit into a single self-contained Pascal source. The postprocess() step injects virtual Destroy on TASTNode / TTypeDesc and strips `override` from non-vtable root classes. |
