Asignments 25.you تحتاج على الأقل 50 لمنتصف 2 النهائي 3.Midterm تاريخ الثلاثاء 3 مارس 2015 4 30-6 20 مساء. سنقوم باستخدام piazza. no المطلوبة كتاب. ماذا يحدث عند ترجمة وتشغيل البرنامج. ما هو مترجم. لغة عالية المستوى - مترجم - مستوى اللغة. هذا هو شائع، ولكن ليس دائما في حالة. أكثر عموما. مصدر اللغة - مترجم - الهدف اللغة. برنامج المصدر - مترجم - الهدف البرنامج المكافئ، لبعض تعريف المكافئ. لماذا نحن بحاجة إلى مترجم - مساعدة البشر كتابة التعليمات البرمجية. easier للناس لفهم و program. lets التي تختارها اللغة الصحيحة للوظيفة التي تريد أن تفعل. سلامة - مترجم يساعدك، يتيح لك معرفة ما إذا كنت إعادة القيام سيئة devices. abstraction - يمكن كتابة البرامج دون فهم كيف إيفريثينغ works. Why نحن بحاجة إلى مترجم - لماذا يمكن ر الكمبيوتر فقط تشغيل لغة المصدر مباشرة. مستوى مستوى اللغة هو الجهاز تعتمد الجهاز محددة - الأمثل لتشغيل بشكل جيد على أجهزة محددة - ولكن شفرة المصدر هو الجهاز مستقلة. نظرة فاحصة على المترجم. كمترجم CS241 - ليس صحيحا بالضرورة لكل compiler. scanning تطبيع الإدخال على سبيل المثال تطبيع المسافة البيضاء - يمكن أن يكون المثال إذا كان بيان إف يحصل على رمزية إف. والخطوتين الأولتين هي التحليل النحوي. مثال رمز التجمع إضافة 3 5 7 جر 31.note أسمبلر هو نوع سبيسيفك من المترجم الذي يترجم بين رمز التجميع ورمز الجهاز. نحن إعادة الذهاب إلى أن يكون الترميز هذه العملية برمتها. عدد ثنائي. في 0 أو 1 التجريد من انخفاض الفولتية العالية أو المغناطيس. بايت 8 بت على سبيل المثال 11001001.There هي 256 2 8 ممكن bytes. Word آلة محددة تجميع bytes.4 أو 8 بايت 32 بت أو 64 بت. نحن ذاهبون إلى استخدام كلمة 32 بت - وهذا يهم عندما نولد وتجميع رمز التجمع. الجزء 4 بت نصف a بايت. تذكر بايت في ذاكرة الكمبيوتر، ماذا يعني على سبيل المثال 11001001.It يمكن أن يكون عددا تقليديا في ثنائي هو 2 0 2 3 2 6 2 7 1 8 64 128 201.It هو قيمة غير موقعة الانتظار ، كيف يمكننا تمثيل الأرقام السلبية. نهج بسيط علامة حجم التمثيل. ريسرف في رست بت ل ريبريسنت علامة 0 يعني إيجابية، 1 يعني سلبية - بقية البتات هي magitude. eg 11001001 هو رقم سلبي مع حجم 1001001 73 - حتى قيمتنا هي -73.For 8 بت، ويمكن أن تمثل أرقام شكل -127 إلى 127.0 على حد سواء 00000000 و 10000000 - تمثيلين للصفر تحتاج إلى مقارنات ل نول - ليست جيدة. أخرى الجانب السلبي - الحساب هو صعبة. إذا كان لدينا إلى إيجابية أو اثنين من القيم السلبية، هل إضافة العادية ل ماغنتيوديس واستخدام علامة مشتركة. ولكن ماذا لو علامات مختلفة طرح قيمة أصغر من قيمة أكبر واستخدام علامة أكبر - مفرطة في التعقيد ليست جيدة. الأرقام السالبة - نهج أفضل - 2S مجاملة. تفسير الرقم كما unigned. if أول بيت هو صفر، ثم done. else، طرح 2 n.111 7 - أول بت ليست 0 - طرح 2 3 - -1.101 5 - أول بت ليست 0 - طرح 2 3 - -3.1100100 من قبل هو الآن -55.To الحصول على مجاملة الثناء نفي عدد n - بت، طرح عدد من 2 n. Alterntaively، و شفة بت 0- 1، 1- 0 وإضافة one. Binary - عشري. ل 8 بت، وهذا يعطي -128 إلى 127.note -128 لا يوجد لديه نفي كما 128 لا يوجد تمثيل. eg مع 3 بت 100- 011 1 100 نحصل على نفس الشيء - لا يوجد تمثيل ل negation. Only واحد الصفر. الحساب هو واضح الحساب هو وزارة الدفاع 2 ن يمكنك فقط إضافة لهم مثلك عادة ..Base 16 0 9، و أف حالة لا تهم. كل رقم عرافة هو 4 بت، لذلك 11001001 سوبسكريبت 2 C9 سوبسكريبت 16.subscipt 2 يعني أنه في القاعدة 2.convert ثنائي إلى عرافة بأخذ 4 أرقام chunks. eg 11001001 - اقتحام 1100 1011 - 1100 4 8 12 C 1001 1 8 9 - C9. استخدام 0x كبادئة عرافة على سبيل المثال 0xC9.Given بايت كيف يمكن أن نقول أي تفسير غير صحيح ونيسنغد، علامة الحجم، تكملة tw. We يمكن أن نعرف حقا نحن بحاجة إلى أن نتذكر نيتنا عندما كنا تخزين بايت. ولكن الانتظار نحن لا ر حتى معرفة ما إذا كان هو number. It يمكن أن يكون حرفا - يعتمد على حرف ترميز لك إعادة استخدام. سوف نفترض اتفاقية أسي رمز القياسية الأمريكية للحصول على معلومات إنتيرتشا nge. what لا 11001001 تمثيل. نوع ونيسنغد، علامة الحجم، واثنين من s compliment. it يمكن أن يكون تمثيل character. bit - لذلك نحن لا نعرف ما هي الحرف الذي - سنقوم باستخدام الكلمات لا يزال ولكن مع بت الأولى 0.what شراكتر هو 01001001 I. could يكون عنوان. أسماء عشوائية. المنشأة، أو جزء من واحد تعليماتنا هي 32 بت. يمكننا أن نعرف حقا نحن بحاجة إلى تذكر نيتنا عندما كنا تخزين بايت. لغة آلة - MIPS. What التعليمات تبدو مثل. ما تعليمات هناك. وسوف نستخدم ميبس تبسيط 18 أنواع التعليمات 32 بت مختلفة. الأجهزة و داتاباث. أدمغة الكمبيوتر. تحكم وحدة. الاستشعار وفك التعليمات. كودينياتس إيبوت و output. Datchesatches إلى أجزاء أخرى من الكمبيوتر لحملها output. ALU وحدة الحساب والمنطق. ريسبونزيبل للرياضيات والعمليات المنطقية والمقارنات. MIPS 32 سجلات الأغراض العامة. 0 هو دائما 0. 30 و 31 هي خاصة من قبل الاتفاقية. على سبيل المثال تسجيل العملية. إضافة محتويات السجلات s و t، وتخزين النتيجة في d. represented بواسطة d - s t.32 السجلات، 5 بت لكل سجل 2 5.3 سجلات للتعليمات 15 بتة جانبا للسجلات 17 بتة تبقى لتشفير العملية. الضرب يعطي نتيجة 64 بت - 32 بت الأولى هي في مرحبا والثانية 32 بت في LO. HI و لو نتائج مخزن ولكن يمكنك ر الكتابة لهم مباشرة - هناك أوبس لنقل القيم من عالية ومنخفضة. هنا يمكن أيضا تخزين الباقي من القسمة وو لو. رام - ذاكرة الوصول العشوائي. هذا هو الذاكرة الرئيسية لل computer. This هو كمية كبيرة من الذاكرة المخزنة بعيدا عن البيانات CPU. The يسافر بين وحدة المعالجة المركزية وذاكرة الوصول العشوائي والحافلة. نحن نفكر في الحافلة كما 64 أسلاك توصيل اثنين من المكونات. رام هو مجرد مجموعة كبيرة من n بايت n.10 9 a جيجابايت. كل بايت لديه عنوان، تشغيل من إلى n-1، ولكن نحن مجموعة كل شيء على ترتيب كلمة ، ولذا فإننا سوف تستخدم عناوين القسمة بنسبة 4، وكل كتلة 4 بايت هو كلمة. ورد لديها عنوان 0x0، 0x4، 0x8، 0xC، 0x10، 0x14، 0x18، 0x1C، 0x20 الخ البيانات المتنقلة بين ذاكرة الوصول العشوائي و CPU. Transfer كلمة من عنوان محدد إلى سجل محدد. الموضوع المطلوب يذهب إلى سجل ذاكرة الذاكرة مار، ثم يخرج على الحافلة. عندما يصل في وذاكرة الوصول العشوائي، يتم إرسال البيانات المرتبطة مرة أخرى على الحافلة ويذهب إلى الذاكرة مدر تسجيل البيانات. يتم نقل محتويات مدر إلى السجل الوجهة. تخزين تماما مثل الحمل، ولكن في عكس. كيف الكمبيوتر يعرف أي الكلمات تحتوي على تعليمات والتي تحتوي على بيانات مفاجأة فإنه لا t. There هو سجل خاص يسمى بيسي برنامج مكافحة الذي يحمل عنوان تعليمات نيكست لتشغيل. بالتفاقية، ونحن نضمن أن بعض عنوان ثابت يقول 0 يحتوي على رمز ومن ثم تهيئة الكمبيوتر إلى 0.Then وحدة التحكم تدير الجلب-تنفيذ التنفيذ. كيف يحصل البرنامج على التنفيذ. هناك برنامج يسمى محمل، الذي يضع البرنامج في الذاكرة ويحدد جهاز الكمبيوتر إلى عنوان التعليمات الأولى في البرنامج. ما يحدث عندما يكون البرنامج ن إيد للعودة السيطرة على محمل الكمبيوتر يتم تعيين إلى عنوان التعليمات التالية في محمل. الذي التعليمات هو أن. 31 سوف دائما تخزين العنوان الصحيح للعودة إلى، لذلك نحن بحاجة فقط إلى تعيين جهاز الكمبيوتر إلى 31. ملاحظة استخدام 31 هو convention. We سوف تستخدم الأمر تسجيل القفز جر لتحديث قيمة الهندسة المعمارية PC. hardware اللغة المينية . الذاكرة الرئيسية مقابل السجلات. 32 سجلات الأغراض العامة. 31 عنوان الإرجاع - في بداية البرنامج تعيين للعودة عنوان محمل، يجب أن برامجنا تنتهي دائما عن طريق القفز إلى أن عنوان المرسل 31 باستخدام الأمر تسجيل القفز جر. 30 هو أننا لا نعرف حتى الآن. ب - برنامج مكافحة - يحمل عنوان إيسنتروكشيون المقبل لتنفيذ. مثال إضافة 2 القيم في سجلات 5 و 7، تخزين النتيجة في تسجيل 3، ثم عودة. مثال إضافة 42 و 52، مخزن سوم في 3 وعودة النتيجة في تسجيل 3، ثم عودة. xxd - cols 4. هذا الأمر سوف تظهر عرافة code. xxd - cols 4 - bits. adding الخيار بت يظهر binary. the حجم الملف هو تعليمات 4 بايت. وسوف تبدأ كتابة برامجنا ليس في ثنائي وعرافة، ولكن مع mnemonics. There بسيطة هي ترجمة إلى المجمع ثنائي المطلوبة كل تعليمات التجميع يتوافق مع تعليمات الجهاز واحد تقريبا. نحن إعادة النظر في example. beq السابق الذهاب إلى مكان آخر إذا اثنين من السجلات هي متساوي. الذهاب إلى مكان آخر إذا اثنين من السجلات ليست متساوية. تعليمات زيادة بيسي من قبل عدد معين من الكلمات إلى الأمام أو الخلف. ما هي قيمة جهاز الكمبيوتر قبل يتم تنفيذ الفرع. بناء على جلب-- تنفيذ دورة، بيسي بالفعل تم زيادة إلى نقطة في التعليمات التالية ب بعد أن تم فك تشفير التعليمات وتنفيذها. هنا، تعويض هو نسبة إلى التعليمات التالية. أمر آخر سلت - تعيين أقل من. a -1 إف بك، a سيت تو 0 other. Example حساب القيمة المطلقة 1، تخزينه في 1 و ريتورن. للقيام بذلك نحن بحاجة إلى استخدام الفروع ويقفز لتعديل PC. how عن نبدأ مع الإصدار c إذا كان x 0 x - x. Example مجموع الأعداد الصحيحة 1 13، مخزن في 3 والعودة c. What إذا كنا لا يمكن استخدام يبني حلقة - goto. Branch الإزاحة -5 لأن بيسي يشير في التعليمات التالية. ينفينيتي في إعداد رمز 1 إلى 1 على كل التكرار من حلقة. الوقت الضخم الجمعية program. sum الأعداد الصحيحة 13 13، مخزن في 3 والعودة. البرامج مع RAM. lw هو تحميل كلمة تعليمات. تحميل كلمة من ذاكرة الوصول العشوائي إلى log. syntax لو a، أنا b. loads الكلمة في ميم ب ط في. b هو قاعدة التسجيل، أنا isoff. sw هو كلمة مخزن تعليمات. يستعد كلمة من تسجيل في RAM. syntax سو a، أنا b. stores كلمة في موقع الذاكرة ميم ب i. Example 1 يحمل عنوان صفيف و 2 يحمل طول الصفيف استرداد العنصر مع الفهرس 5 وتخزينه في التسجيل 3.Now نفعل ذلك مرة أخرى ولكن أكثر تجريدا في هذه الحالة، لا يعرف المؤشر نحن need. mult تعليمات المضاعفة . منذ ضرب اثنين من أرقام 32 بت قد يؤدي إلى عدد 64 بت، يتم تخزين النتائج في اثنين من السجلات الخاصة مرحبا و lo. syntax مولت أ، b. div تعليمات الانقسام. الحاصل هو سترويد في لو، والباقي يتم تخزينها في hi. syntax ديف a، b. mfhi و مفلو التحرك من هاي والانتقال من لو تعليمات. مع القيم من مرحبا أو لو على التوالي في معين. s.statax مفهي د، مفلو د. التسميات إعادة النظر في حلقة. استعادة حلقة كان لدينا مجموع الأعداد الصحيحة 1 13، مخزن في 3، ثم عودة. كان الأمر ليس داخل حلقة لدينا، والتي يمكن نقلها خارج. هذا أمر جيد، ولكن الآن بن في النهاية لديها وينبغي أن يكون فوري غير لائق -3.في الحلقات نيستر، وهذا هو كابوس هذا لأننا استخدمنا المتفرعة الصريحة، إضافة إزالة تعليمات يعني أننا يجب أن يغير فرع أوفسيتس. بدلا من ذلك، يسمح المجمع أسمنتل تعليمات. سينتاكس هو التسمية تعليمات. الجمعية الزميلة التي اسم تسمية مع تعليمات. عندما يرى المجمع التسمية، فإنه يحسب الفرق بين الكمبيوتر وأعلى، من حيث الكلمات. إيغ أعلاه التسمية-- بيسي 4 0x14 -0x20 4 -0xc 4 -12 4-3. الآن يمكننا إعادة كتابة مثال حلقة مع تسمية. إجراءات الإجراءات وظائف في التجمع يسمح لنا لإعادة استخدام التعليمات البرمجية. لدينا اثنين من المشاكل لحلها. العودة والعودة كيف يمكننا نقل السيطرة إلى والخروج من الإجراء، المعلمة يمر، الخ. كيف يمكننا التأكد من أن الإجراءات لا الكتابة فوق المهم البيانات. وسوف نبدأ مع المشكلة الثانية. يمكننا حجز سجلات ل برودسيدور f، وبعض للخط الرئيسي مع عدم التداخل، ولكن إذا إجراءات استدعاء إجراءات أخرى أو أنفسهم، نحن نفد من السجلات. بدلا من ذلك، وسوف تسمح الإجراءات للقيام كل ما يريدونه مع السجلات، طالما أنه يضعهم على العودة إلى قيمهم الأصلية عند الخروج. لذلك نحن بحاجة إلى استخدام ذاكرة الوصول العشوائي كيف يمكننا الحفاظ على الإجراءات من استخدام نفس ذاكرة الوصول العشوائي. لمنع إجراءات من استخدام نفس عناوين ذاكرة الوصول العشوائي، ونحن نستخدم كومة مؤشر يقع مؤشر كومة في تسجيل 30، وهو السجل المقيدة الأخرى التي سبق أن ناقشنا. أساسا، ونحن تخصيص الذاكرة من أعلى أو أسفل ذاكرة الوصول العشوائي الحرة، بطريقة أو بأخرى تتبع ما لا يتم استخدام ذاكرة الوصول العشوائي. آلة تساعدنا على الخروج من 30 يتم تهيئة من قبل لوادر إلى الماضي فقط الكلمة الأخيرة من الذاكرة. نستخدم 30 كمرجع لفصل ذاكرة الاستخدام المستخدمة وغير المستخدمة، إذا كنا تخصيص من القاع. نستخدم ذاكرة الوصول العشوائي مثل كومة، تتحرك صعودا على وظيفة يدعو وأسفل على العائدات. استراتيجيتنا كل إجراء يدفع السجلات التي سوف تستخدم على كومة والملوثات العضوية الثابتة القيم الأصل من كومة عند الانتهاء 30، مؤشر كومة، يحتوي على عنوان الجزء العلوي من المكدس. الطريقة للإجراءات. إكسامبل لنفترض وظيفة و يستخدم فقط 2 و 3. لماذا نحن حفظ السجلات ومن ثم ضبط مؤشر المكدس. لأن مرة واحدة يتم حفظ السجلات، يمكننا استخدام واحد لعقد فلو تعديل فلو. إجراءات البرمجة التجميع. الآلة لديها فقط 32 السجلات كيف نتأكد من عدم كتابة البيانات الهامة. رمز للاتصال والعودة. عندما نعود من إجراء، ونحن بحاجة إلى تعيين جهاز الكمبيوتر إلى الخط بعد جر هنا كيف نعلم أي عنوان هذا الأمر is. jalr هو القفز وربط السجل. التعليم هو تماما مثل جر، ولكن فإنه يحدد أيضا 31 إلى عنوان التعليمات التالية أي PC. assembly كود يبدو الآن مثل. وهكذا من أجل العودة إلى محمل يجب علينا حفظ 31 على المكدس أولا ثم البوب ​​قبل العودة. الأسهل خيار هو تمرير العودة معلمات عن طريق السجلات. ومع ذلك، يجعل هذا الأمر معقدا فيما يتعلق بمعرفة أين السجلات معلمات هي. إذا تم ذلك، يجب على الكاتب الإجراء توثيق التعليمات البرمجية بحيث العميل يعرف أي السجلات سيتم تمريرها إلى الوراء وإلى الأمام. أكبر مشكلة هي أن هناك فقط 32 سجلات أفضل خيار دفع المعلمات على كومة هذا يتطلب أيضا document. Full التعليمات البرمجية سبيل المثال - سوف نكتب وظيفة التي سوف نجمع أرقام n الأولى. لا حاجة إلى آلات إضافية. إذا السجلات والمعلمات، والمكدستدار بشكل صحيح، وسوف العودية العمل. الإدخال والمخرجات. إدخال غير معتمد التعامل معها. يوفر ميبس موقع 0xffff000c دعا ذاكرة الفيديو، لتخزين الكلمات حيث سيتم طباعة بايت الأقل أهمية إلى الشاشة. الطباعة عينة كس، تليها خط جديد. المجمع المجمع هو برنامج يترجم رمز التجميع إلى رمز آلة مكافئ. رمز التجميع إضافة 1، 0، 0 - أسمبلر - رمز الجهاز 0100010.Any ترجمة ينقسم ينطوي على خطوتين. تحليل فهم ما هو المقصود من مصدر الناتج. synthesis ما يعادل ملف الهدف. ملف التجميع هو مجرد تيار من الأحرف ملف نصي. خطوة 1 أحرف المجموعة إلى الرموز ذات مغزى على سبيل المثال، تسميات، أرقام عرافة، أرقام كلمة عادية، سجلات، الخ وقد تم هذا الجزء بالنسبة لنا سنتحدث حول ذلك في مزيد من التفاصيل. على سبيل المثال ل C كود البدء، كل رمز هو مثيل من فئة رمزية. خطوة 2 الرموز المجموعة في تعليمات، إذا كان ذلك ممكنا التحليل. خطوة 3 الناتج ما يعادلها آلة رمز التوليف. إذا الرموز ليست مرتبة في تعليمات معقولة، الإخراج خطأ إلى خطأ قياسي.

We often find it convenient to split MIPS programs into smaller units, for the same reason as with higher-level languages There is a major issue How can an assembler resolve a reference to a label in a different file. We have and with shared labels. Solution to assemble, concatenate the files and then assemble. cat java. This works, but it doesn t save us any work if I make a small change in but is huge. Also, I may only want to give someone the binary not the source We want to compile first then link after. Solution 2 Can we assemble first and then cat. header binary reloc table. No, they are all assembled to start at address 0, but the second two would need to relocatable. Thus w e need to assemble to MERL, not just MIPS However, if we cat two MERL files, we don t get a MERL file. Solution we need a tool smarter than cat. It must be able to understand MERL files and put them together intelligently. Such a tool is called a linker. And yet what should an assembler do with references to lables it cannot find. We will need to change the assembler. Aside what happens conceptually when I run g. asm o kind o lexer o -- assembler outpiler generates asm o, kind o, lexer o. o extention used to represent object files. linker combines the o files into an executable. Import and Export. We lose a valuable error-check. If a label is not defined, then our old assembler assumes an error. but now we just expect to find it within a linked-in file. How can an assembler tell between errors and intentional behaviour. The new assembler directive. id tells the assembler to ask for id to be linked in This does not assemble to a word MIPS. if we have a label abc, and that label does not occur, and no abc, then we have an error. Format code 0x11 means External Symbol Reference ESR. we need the name of the symbol, the address of use where the blank needs to be filled in. ESR entry contains. word 2 location of where symbol is used. word 3 length of symbol in chars n. word 4- 3 n ASCII chars in the symbol name one word per char. example ESR entry. How do we know which vsion of abc to use We can t assume labels won t be duplicated. makes id available for linking - this does not assemble to a word of MIPS. tells the assembler to make an entry in the MERL table. MERL entry tpe External Symbol Defintion ESD. ESD entry contains. word 2 address the symbol represents. word 3 length of symbol name n. word 4-3 n ASCII name. example ESD Entry. MERL now contains code, relocator addresses, addresses and names of ESR and EDR entries. Note that instructions referring to external symbols must also be relocated. Augment MERL files to help linker. MERL Header Code Relocation and External Symbol Table. Symbol table contains relocatable addresses, adresses and names of ESR imports and ESD exports. The linker Given two MERl files - how do we link them What are the steps. a - we want to subtract the header from m2 and then push forward by length of m1 code a relocate by a add a to every address in. resolve symbols and check for duplicates in exports - ERROR. if AND 0 then ERRROR for all addr1, label in do if exists addr2, label in then - addr2 remove addr1, label from add addr1 to for all addr2, label same. merge symbol tables. imports and exports and relocates and. output linked program with new header. output MERL cookie output totalCodeLen total imports, exports, relocates 12 output totalCodeLen 12 output output output imports, exports, relocates. Assembly language has a simple structure, is easy to parse, straightforward and unambiguous. Now we turn our attention to the compiler Source program - compiler - assembly code equivalent meaning. First step of our compiler source program - scanner lexical analysis - tokens. A high-level language is a more complex structure It is harder to recogn ize, and we have no single translation to machine code To convert to machine language we use a compiler. How does a compiler recognize if a given program is valid Note we re not asking if it s logically correct a much harder problem , but just whether the sequence of characters forms and allowed program based on the specifications of the language. Eventually, once the compiler can recognize whether a program is valid, how do we translate the program into an equivalent program in the target language usually lower-level. Is this a valid c program. what about the same program with a b 5 s. no it will be parsed as a b which is invalid. nope, same interpretation as above. How can we handle this complexity. We want a formal theory of string recognition - general principles that work in the context of any programming language. alphabet finite set of symbols e g typically denoted. String word finite sequence of symbols from a, abc, cbca, etc. Length w of symbols in w. Empty string is the empty string, not a symbol 0.Language a set of strings e g , b, aab, aaaab. is the empty word, while is the empty language. is a singleton language containing only the empty word. How can we automatically recognize whether a given string belongs to a given language This is mindblowing, and depends on how complex the language is Since the answer is dependent on language complexity, we will charactertize languages according to how hard recognition process is we will create classes of languages based on the difficulty of recognition This is based on Chomsky Hierarchy. Finite easy. Regular not so easy. Context-free pretty decent. Context-sensitive challenging. Recursive difficult. anything-else impossible. We want to study high-level languages at as easy a class level as possible, and move down when we have to. These languages have finitely many words. Write code to answer w L such that w is scanned exactly once, without storing previously seen characters. We can recognize a word by comparing each word in the finite set of words - but we won t use that approach. started compi ler. formal languages. chomsky hierarchy. context sensitive. very losely, recursive means that there is an algorithm or program to determine whether any given input is a member of the language. An abstraction of this program. Circles are states - configurations of the program based on input seen. The double circles are accepting if the program halts there. Example - mips operators. Since programming langagues don t usually admit only a finite many programs, finite languages are not much use. These languages are built from finite languages, but also support the following operations. Example show that is regular. This syntax is very tedious We have Regular Expressions. Question - is the language C regular. We have IDs a-zA-Z. A C program is a sequence of tokens, each of which come from a regular language. How can we define which sequences of tokens are valid We don t know yet. Thus, our answer is maybe. Can we recognize arbitrary languges automatically. Can we harness what we learned about recognizing fini te languages LOOPS. These machines are called Deterministic Finite Automata DFAs. Always a start state. For each character in the input follow the corresponding arc to the next state. If in an accepting state when input is exhausted, accept - else reject. What is missing. What if there is no transition Consider the ab example - what if our input is ab If we fall off the machine, reject More formally, an implicit error state exists all unlabelled transitions go there An error state has an all input loop back to itself and is non-accepting. Example String over with an even number of a s and an odd number of b s. Formal definition of DFA a DFA is a 5-tuple , Q, q0, A, , where. is a finite non empty set alphabet. Q is a finite, non-empty set states. q0 is an element of Q start state. A is a subset of Q accepting states end states. Qx - Q Transition function state and input symbol and gives next state. consumes a single character of input. we can extend to a function that consumes an entire word. Thus, a DFA, M , Q, q0, A, accepts a word w if q0, w is in A. example from before. Last time Regular Expressions. Handy to know precedence highest to lowest. Example a bc is a b c. A DFA, M , Q, q0, A, accepts a word w if q0, w is in A. If M is a DFA, we denote L M the language of M , the set of all words accepted by M L M. L is regular iff L L M for some other words, the regular languages are accepted by DFAs. Proof we will prove this later. Implementing a DFA. Unfortunatley this is very tedious Instead, we could use a lookup table see provided assembler starter code of states in columns and characters in rows - where they intersect is next state. Currently, our DFA takes an input string and returns yes no whether the given string is in the language However, it is possible to add an output facility to a DFA, resulting in a transducer. DFAs with actions can attach computation to the arcs of a DFA For example, consider L , where we compute the value of the number. sorry for horrible quality. another possible action would be emit a token - here we emit the current value of our number. Non-Deterministic Finite Automata What do we gain by making our DFAs more complex e g L w ends in abb. What if we allowed more than one arc edge with the same label from the same state. The machine choses one this is non-deterministic. We can think of it as magic, that it knows where it goes - or we can think of it as trying every path and see if there is any path that ends in an accepting path, then it accepts. We will accept if some set of choices leads to an accepting state Returning to our example.- start - a - - b - - b - start loops back to itself with a and b. The machine guesses to stay in the first state until it reaches the final abb, then transitions to accepting. NFAs are often simpler than DFAs. Formally NFA is a 5-tuple , Q, q0, A., Q are finite non-empty sets alphabet, states. q0 start and A subset of Q accepting. relation - Qx -- subsets of the powerset of Q 2 Q. This is the powerset of Q, which makes it non-deterministic The powerset is the set of all subsets of Q includes the empty set and Q. We want to accept if some path through the NFA lead to an accepting state, and reject if no such path exists. for NFAs sets of states x - sets of states. P, empty P, where P is a set of states. P, cw union of q, c for all q in P w. And we accept if, w union A 0. NFA Simulation Procedure. work with the following NFA, we will simulate baabb. BUT WAIT I am adding the right column to the table above as we speak If we give each set of states a name, and call those states, every NFA becomes a DFA For example. note if we draw this it looks just like our DFA from before. Holy cow, we have a DFA because D contains an accepting state. Consider L U with an even of a s We can draw an NFA. The DFA is much harder to produce Let s do a trace. Now we build the DFA via the subset construction. Accepting state are any states that includes an accepting state from the original NFA Every NFA hs an equivilent DFA, and NFAs recognize the same class of languages. What if we let ourselves change state without consuming a character We call these transitions we label the arrow as. This is a free pass to a new state without reading a character. This makes it easy to glue smaller automa together. Revisiting the abov e example. By the same renaming trick as before ie the subset construction every - NFA has an equivilent DFA Thus, - NFAs and DFAs recognize the same class of languages. Yes, DFAs and NFAs are finite state machines and the class of languages accepted by FSM are regular languages. Proof of Kleene s theorem one way. L is regular if L L M for some DFA M. If we can find an - NFA for every regular expression, then we have proved one direction of Kleene s theorem. The below pictures show empty languages, languages, single caracter, alternation, concatenation, repetiton. Thus every regular language has an equivalent NFA, which has an equivalent DFA and the conversion can be automated. Is C a regular language. C keywords, identifiers, literals, operators, comments, punctuation. These are all regular languages, and sequences of these are also regular, so we can use finite automata to do tokenization scanning, lexical analysis. Ordinary DFA can only tell us if a word is in a language We need something that takes an input string w, breaking w into w1,w2 wn such that each wi is in L and then output each wi. Consider L is regular. Let ML be the DFA that recoginizes L Then the second representation M which is a nonempty sequence of tokens is NFA modified from the NFA for ML - using t he rules from above for. We can add an action to each each - move such as output a token Our machine is non-deterministic - moves are optional. The question does the current setup guarantee a unique decomposition w w1 w2 2n The answer is no. Consider just the portion of the machine that does IDs.- --a-zA-Z-- --a-zA-Z0-9-- back to ending state. output token from ending state back to start state. The input abab could be interpreted as 1,2,3 or 4-tokens. How can we fix this We could always return the longest possible next token However, this can still fail. Consider L , w aaaa. If we take the longest possible token, we take aaa first and then we are stuck. However, we could have tokenized the string successfully as aa and aa. Oh well It would be bad to design a programming language like this. But wait many of the languages we use are designed like this. Remember the example when we started. c a b - a b NOT a b. Again from out example, c a b - a b which is invalid. But, a b would be valid - but that s not what the compiler does. Another example from c. vector vector v. c treats the like the bitshift operator instead of two closing angle brackets We have to trick the scanner. vector vector v. Fixed in c 11. Maximal Munch Algorithim. Simplified Maximal Munch as above, but if we are not in an accepting state, when no transition possible, then we ou tput an error don t backtrack. Our identifier must start and end with a letter and may contain a single. We also accept operator. For input ab. we find a valid start state, then b, and then -, but we cannot scan past this point since no further action is possible. Thus we would go back ab since it was the last valid point, and then continue from there. THe SMM algorithm would simply find an error but in practice this is usually sufficient. Note that if we have L we show it s regular by describing it with a regular expression - using only operations in regular expressions that we talked about - here it s aa. Scanning algorithm - Maximal Munch vs Simplified Maximal Munch. difference - no backtracking. Now consider alphabet of brackets. Can we build a DFA for L. Each new state lets us recognize one more level or nesting, but no finite number of states recognizes all levels of nesting, and a DFA must have a finite number of states. tokens Parsing syntactic analysis parse tree. what is required. Given a formal syntax specication, the parser verfiies whether the incoming tokens have a valid syntax confirming to the specifications and outputs a parse tree to allow semantic analysis in the following step. This cannot be done with regular languages, so we move to the next class in the Chomsky Hierarchy. These are languages which can be described by a context-free grammar a set of rewrite rules. Following the balanced paranthesis example. a word in the language surrounded by S - S. the concatenation of two words in the language S - SS. The shorthand for this is S - S SS. Example show how this system generates. The notaton we have used. means derives. a - means can be dervied from a by one application of a grammar rule. we formally define a context-free language to consist of. an alphabet of terminal symbols. a finite non-empty set N of of non-terminal symbols, such that N union null set. we often use V vocabulary to denote N U. a finite set of P productions, where productions have the form A - , A in N, in V. an element S in N as the start symbol. In our parentheses example, we have that terminal symbols are , non-terminal symbols are , and S is our start symbol. a, b, c are elements of characters, terminals. w, x, y are elements of words. A, B, C S are elements of N non-terminals. S is the start symbol., , indicate elements of V. We write A if there is a production A - in P. means that delata1 1 n for n 0.Definition L G , where L G is the langauge specified by G. Note that this is a set of strings of terminals only A language L is context-free if L L G , for some context-free grammar G. Example Palindromes over. S - a b c aSa bSb cSc. We can also define this as. S - aSa bSb cSc M. Show that S abcba. S aSa abSba abMba abcba. This proccess is called a derivation. But we could have speciiced this with a regular expression. Show that S a b. S S op S a Op S a S a b. alternatively S S op S S op b S b a b. Note that we have a choice over which symbmol to expand first. Leftmost Derivation always expand leftmost symbol first. Rightmost Derivation always expand rightmost symbol first. We are showing too much information, since this information doesn t matter and this can get very long We can express them naturally and succinctly as a tree stucture. Example consider abcba. For the leftmost derivation, there is a unique corresponding parse tree and vice versa. Midterm - we will provide. MIPS reference sheet. MERL file format spec. ASCII chart. CFL context free languages CFGs. In a derivation, one non-terminal in the current string is selected and replaced or rewritten using RHS of a production rule for that non-terminal. e g production rules. What is the RE for this langugae. Leftmost derivation for a bxc S S Op S a Op S a S a S Op S a b Op S a b x S a b x c. Or, expand the first S first S S Op S S Op S Op S a Op S Op S a S Op S a b Op S a b x S a b x c. These correspond to DIFFERENT parse trees A grammar for which the same word has more than one distinct parse tree is called ambiguous The grammar we defined above is ambiguous If we only care about whether a string is in the language, the ambiguity doesn t matter. As compiler writers we want to know why a word is in a language, so the derivation matters Why does it matter The shape of the parse tree describes the meaning of the word, so a word with an ambiguous parse may have multiple possible meanings. In the first tree, bxc is grouped more tightly, and in the second a b is grouped So it could mean a bxc or a b xc. END MIDTERM CONTENT. What do we do about this. use heuristics precedence to guide the derivation proccess. Make the grammar unambiguous. Then we have a strict left to right precedence. new producton rules that prevent uncessary brackets. new derivation NOTE use single arrows for production rules and double arrows for derivation. If L is context-free, is there always an unambiguous grammar. No There are ineheritently ambiguous languages that only have ambiguous grammars. Can we construct a tool to tell us if a grammar is ambiguous No This is undecidable There is provably no algorithm to solve this problem The equivalence of grammars is also undecidable. We need to build a recognizer - what class of programs recognize CFLs. regular languages are represented by DFAs, a program with finite memory. Context-free languages must recognize infinite memory, they are represented by NFA with a stack. But we need more than a yes no answer We don t want to have a program and the compiler just say yes or no. We ca n use grammars to specify the syntax of a language For example, a while loop. Parse trees allow us to understand the program We need to know the derivation parse tree and error diagnosis The problem of finding the derivation is called parsing How do we use grammar to go from source program to a parse tree. We have two choices. forwards - top down - start at S, work to w. backwards - bottom up - start at w, work to S. How can we derive S abywx We want an algorithm to generate the derivation. Consider a leftmost derivation. What are we doing here Match input symbols startng from left until you encounter a non-terminal Replace non-terminal with RHS of a rule and continue matching more formally. Use the stack to store s in reverse and match against characters in input. Invariant the consumed input plus the reverse of the stack contents is equal to i Sean calls these left right sentential forms - for leftmost rightmost derivations. For simplicity, we will use augmented grammars for parsing We invent two new symbols BOF and EOF and a new start symbol S. say w BOF a b y w x EOF. Let s codify this. When the top of other stack is a terminal pop and matched against the input. when TOS top of stack is a non-terminal A, pop A and push reverse , where A - is a grammar rule. accept when stack and input are empty. brute force try all combinations until one works - this is inefficient. we want a Deterministc Procedure with no backtracking. our solution is to use the next symbol of input lookahead to help decide. Construct a predictor table - given a non-terminal on the stack and an input symbol, tell us which production to use Empty cells are errors. The rest of the table can be used for descriptive error mesesages Parse error at row, col expecting one of symbols where the predictor table does have entries. What if a cell contains more than one rule The method breaks down. This grammar is called LL 1.L left to right scan of input. L leftmost derivations produced.1 1 symbol of lookahead. top down parsing - starting with s ending at w - recall that triangle diagram. We can automatically compute the predictor table. Predict A, a - rules that apply when A is on the stack and a is the next input character. First , in V is the set of characters thata can be the first letter of a derivation starting from. For example First AyB. So Predict A, a.However, this is not quite right What if A. Then a might not come from A, but from something AFTER A. We missed something - what if there is more than one production with the same LHS How do we know which one to pick. So, Predict A, a U. Nullable true if , false otherwise. Follow A the set of terminal symbols that can come immediately after A in a derivation of S. In our example Follow Aputing Nullable - Nullable true if .
