Function bakeConstStringKey

src/ast/ast_simulate.cpp:127–133

Const-string table key: bake the key bytes (into the const-string heap) and their hash at simulate time so the runtime node skips the per-lookup hash_blockz64 walk. Returns the baked key char* (and sets outHash) when keyType is string and keyExpr is an ExprConstString; nullptr otherwise (caller falls back to the regular hashing node).

    // baked key char* (and sets outHash) when keyType is string and keyExpr is an ExprConstString;
    // nullptr otherwise (caller falls back to the regular hashing node).
    static __forceinline char * bakeConstStringKey ( Context & context, Expression * keyExpr,

        if ( keyType->baseType != Type::tString || !keyExpr->rtti_isStringConstant() ) return nullptr;
        char * keyStr = context.constStringHeap->impl_allocateString(static_cast<ExprConstString*>(keyExpr)->getValue());
        outHash = hash_blockz64((uint8_t *)keyStr);
        return keyStr;
