From 4df7c22b99349dcf2175d69679eafa175d49aa9f Mon Sep 17 00:00:00 2001 From: _ov4 Date: Sun, 26 Jul 2026 12:02:32 +0000 Subject: refactor: batch 1 - correctness and error contract - MID/RIGHT/LEFT integer args now coerced at call sites (RIGHT(s, n/2) no longer emits invalid IR); drop emitLeft's private conversion - FOR loop direction decided at run time via select on STEP sign; descending FOR works, STEP evaluated once per iteration - ArrayHandler: extract emitCheckedIndices/loadElement; index count is validated before emission, fixing a compiler-crash (vector OOB UB) on OUTPUT with too many indices - Error contract: Lexer/Parser/CodeGen track errors; all silent failure paths now print Error: diagnostics with line numbers; unterminated char literal no longer truncates the rest of the program; module is verified with verifyModule; driver exits non-zero on any error Co-Authored-By: Claude Fable 5 --- include/cps/CodeGen.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'include/cps/CodeGen.h') diff --git a/include/cps/CodeGen.h b/include/cps/CodeGen.h index 07ff3e8..268ba7e 100644 --- a/include/cps/CodeGen.h +++ b/include/cps/CodeGen.h @@ -59,6 +59,8 @@ class CodeGen { llvm::Value *FalseStr; // "FALSE" llvm::Value *EmptyStringStr; // "" + bool HadError = false; + void SetupExternalFunctions(); llvm::AllocaInst *CreateEntryBlockAlloca(llvm::Function *TheFunction, const std::string &VarName); llvm::AllocaInst *CreateEntryBlockAlloca(llvm::Function *TheFunction, llvm::Type *AllocType, const std::string &VarName); @@ -80,6 +82,8 @@ public: ~CodeGen(); void compile(const std::vector> &Statements); void print(); + bool hadError() const { return HadError; } + void reportError(const char *Fmt, ...); llvm::Value *emitExpr(ExprAST *Expr); void emitStmt(StmtAST *Stmt); -- cgit v1.3.1-4-g156e
