+	<h1>CbCコンパイラの LLVM/clang 3.5上での実装</h1>
+        <p><br>Kaito Tokumori<br>February 11, 2014</p>
+      </article>
+      <article>
+	<h3>研究目的</h3>
+	<p> 当研究室ではプログラムをコードセグメント、データセグメントという単位を用いて書くという手法を提案している。その手法を用いてプログラミングを行う言語として"CbC"の開発を行っており、これはCの下位の言語である。CbCにおいてコードセグメント間の移動はgoto文を用いた軽量継続によって行われ、これはTail Call Eliminationという最適化の強制によって実現される。</p>
+	<p>本研究過去に開発されたmicro-c,GCC版のコンパイラに続くLLVM/clang上でのCbCコンパイラの開発を行う。</p>
+      </article>
+
+      <article>
+	<h3>今回したこと</h3>
+	<ul>
+	  <li>ちょっとしたバグ修正</li>
+	  <li>例題を動かす</li>
+	</ul>
+      </article>
+
+      <article>
+	<h3>ちょっとしたバグ修正</h3>
+	<ul>
+	  <li>コードセグメントを呼び出すときに TailCall フラグが立っていない時エラーを出す処理の部分</li>
+	  <li>呼び出されたコードセグメントを getCalledFunction で取得していたがポインタ経由でアクセスされたものの場合 この戻り値が null になる.</li>
+	</ul>
+      </article>
+
+      <article>
+	<h3>例題を動かす</h3>
+	<ul>
+	  <li>gcc では大丈夫だったが clang では関数のプロトタイプ宣言がないと怒られたので記述. </li>
+	  <li>_CbC_return を __return に. </li>
+	  <li>実装の問題で, {} を使わない if文の下に継続を用いると不具合があったので {} で閉じた. </li>
+	</ul>
+      </article>
+
+      <article>
+	<h3>例題を動かす</h3>
+	<ul>
+	  <li>動いた<ul>
+	      <li>arg.c</li>
+	      <li>conv.c</li>
+	      <li>fact-a.c</li>
+	      <li>factorial.c</li>
+	      <li>goto.c</li>
+	      <li>regexp</li>
+	      <li>stack1.c</li>
+	  </ul></li>
+	  <li>動いてない<ul>
+	      <li>conv1</li>
+	  </ul></li>
+	</ul>
+      </article>
+
+      <article>
+	<h3>conv1.c</h3>
+	<ul>
+	  <li>O0, O1 だと問題なく動作.</li>
+	  <li>O2 以降は引数1, 3の場合にセグフォ</li>
+	  <li>O2 以降の時 TailCallFlag を付け損ねている場合がある. (他の最適化の影響?)</li>
+	  <li>ループ回数を減らすと動作. 261989以上でセグフォ. </li>
+	  <li>gcc側は逆に O2 以上だと動く...</li>
+	</ul>
+      </article>
+
+      <article>
+	<h3>原因調査</h3>
+	<ul>
+	  <li>Inliner の有無がバグの発生に関わっている.</li>
+	  <li>Inliner の設定をO0,O1の場合に統一すると TCE も発生するしプログラムも動く.</li>
+	  <li>Optimize Level に寄る Inliner の設定の違いは InlineThreshold の違い.</li>
+	</ul>
+      </article>
+
+      <article>
+	<h3>次回課題</h3>
+        <ul>
+          <li>if文のやつの対応となんで TCE 失敗してるのか, conv1動かないのかの調査, 修正.</li>
+          <li>論文書かないといけない</li>
+        </ul>

+################################################################
+
+This sample hook safeguards topic branches that have been
+published from being rewound.
+
+The workflow assumed here is:
+
+ * Once a topic branch forks from "master", "master" is never
+   merged into it again (either directly or indirectly).
+
+ * Once a topic branch is fully cooked and merged into "master",
+   it is deleted.  If you need to build on top of it to correct
+   earlier mistakes, a new topic branch is created by forking at
+   the tip of the "master".  This is not strictly necessary, but
+   it makes it easier to keep your history simple.
+
+ * Whenever you need to test or publish your changes to topic
+   branches, merge them into "next" branch.
+
+The script, being an example, hardcodes the publish branch name
+to be "next", but it is trivial to make it configurable via
+$GIT_DIR/config mechanism.
+
+With this workflow, you would want to know:
+
+(1) ... if a topic branch has ever been merged to "next".  Young
+    topic branches can have stupid mistakes you would rather
+    clean up before publishing, and things that have not been
+    merged into other branches can be easily rebased without
+    affecting other people.  But once it is published, you would
+    not want to rewind it.
+
+(2) ... if a topic branch has been fully merged to "master".
+    Then you can delete it.  More importantly, you should not
+    build on top of it -- other people may already want to
+    change things related to the topic as patches against your
+    "master", so if you need further changes, it is better to
+    fork the topic (perhaps with the same name) afresh from the
+    tip of "master".
+
+Let's look at this example:
+
+		   o---o---o---o---o---o---o---o---o---o "next"
+		  /       /           /           /
+		 /   a---a---b A     /           /
+		/   /               /           /
+	       /   /   c---c---c---c B         /
+	      /   /   /             \         /
+	     /   /   /   b---b C     \       /
+	    /   /   /   /             \     /
+    ---o---o---o---o---o---o---o---o---o---o---o "master"
+
+
+A, B and C are topic branches.
+
+ * A has one fix since it was merged up to "next".
+
+ * B has finished.  It has been fully merged up to "master" and "next",
+   and is ready to be deleted.
+
+ * C has not merged to "next" at all.
+
+We would want to allow C to be rebased, refuse A, and encourage
+B to be deleted.
+
+To compute (1):
+
+	git rev-list ^master ^topic next
+	git rev-list ^master        next
+
+	if these match, topic has not merged in next at all.
+
+To compute (2):
+
+	git rev-list master..topic
+
+	if this is empty, it is fully merged to "master".

+# S6 Format
+
+
+## Media Types 
+
+S6 supports out-of-the box three media types, that is, `projection`, `screen` and `print`:
+
+* `projection` => display one slide at-a-time; (use option `mode: slideshow`)
+* `screen`     => display all slides at-once on screen; (use option `mode: outline`) 
+* `print`      => print (and print preview)
+
+Note: Only the Opera browser has built-in support for `projection`.
+On other browsers S6 uses JavaScript to switch `projection` to `screen` on startup.
+
+
+## Structure, CSS Classes
+
+     .presentation
+       .slide
+         .step
+         .notes
+         .extra
+      
+### Core Classes
+
+`.presentation` (alias `.deck`, `.slides`)
+
+Top level class for all slides
+
+`.slide`
+
+Marks a slide
+
+`.step`  (alias `.incremental`, `.delayed`, `.action`, `.build`) 
+
+Marks a slide step. Shortcut Tip: If a list gets marked up with `.step`,
+all its children get marked up automatically.
+
+
+### Extras
+
+`.notes`  (alias `.note`, `.handout`)  
+
+Marks speaker notes.
+
+`.extra`
+
+Marks extra text for print only.
+
+
+
+## Styling and Slide Types
+
+### Slide Types/Layouts
+
+* fullscreen
+* hidden
+

+### r2011-11-13
+
+* Add normalize css selector option; lets you use the following aliases
+  * presentation => deck
+  * step => incremental, delayed, action, build
+  * notes => note, handout
+
+### r2011-11-05
+
+* Add chrome fix/workaround for inline styles (projection media needs to get set to screen,projection)
+* Move code to addons using new slideshow triggers; new addons include:
+  * counter (slide counter e.g. 1/7)
+  * controls (toggle, next, prev buttons, jumplist)
+  * autoplay
+  * footer/header
+* Moved sample transitions to jquery.slideshow.transitions.js
+* Changed .slide box-sizing to border-box (lets you use width: 100%; height: 100%;)
+* Minor fixes
+
+### r2011-11-01
+
+* Add minimalistic.html template; all styles (projection, screen, print) inline plus no less.js used
+* Clean up styles; move all styles (projection, screen, print) for controls into slideshow.js
+* /shared folder now split into /js and /css folders
+* Update jquery.js to 1.6.4
+* Update less.js to 1.1.4
+* Minor fixes
+
+### r2011-05-22
+
+* Adding blank5.html template (using more semantic tags e.g. header, footer, article, etc.) [Thanks Ryan McIlmoyl]
+
+### r2011-05-21
+
+* Switch all CSS stylesheets to use less.js CSS extension
+* Update jquery to 1.6.1
+
+### r2011-05-20  
+
+* Easier CSS media type handling for projection (e.g. ids no longer required; plus can now handle multiple styles either using link or style tag)
+
+### r2011-02-06
+
+* Add right click on title handler for going back one slide
+* Update jquery to 1.5
+
+### r2010-07-18
+
+* Adding custom slide transitions plus some sample animations (e.g. slide up/down, fade out/in)
+* Adding clicker (click on title to go to next slide)
+* Adding autoplay (press a/p/s-key to toggle autoplay)
+
+### r2010-07-17
+
+* JavaScript cleanup; everything namespaced now using Slideshow
+* Removing svg gradient backgrounds; use css3 gradients instead
+* Move better browser banner for IE out of core; uses conditional comments for include.
+
+### r2009-02-19
+
+* Add support for steps/incrementals
+
+### r2009-02-10
+
+* Everything is new.

+## What's S5? What's S6?
+
+Simple Standards-based Slide Show System (S5) is Eric Meyer's (of CSS fame) public domain
+(free, open source) slide show package inspired by Opera Show and others that works
+in all modern browsers without any plugin required
+because it includes its own slide show machinery in JavaScript.
+More [S5 Project Site »](http://meyerweb.com/eric/tools/s5)
+
+S6 started as a rewrite of S5 using the jQuery JavaScript library - offering
+easier to understand and easier to extend code. Add plugins, effects and more.
+Contributions welcome!
+
+## What's Slide Show (S9)? Slide Show Generator for S6 
+
+A Ruby gem that lets you create slide shows and author slides in plain text
+using a wiki-style markup language that's easy-to-write and easy-to-read
+and ships "out-of-the-gem" with S6 templates built-in.
+More [Slide Show (S9) Project Site »](http://slideshow-s9.github.io)
+
+
+## About, License
+
+The slide show (S6) scripts and templates are dedicated
+to the public domain. Use it as you please with no restrictions whatsoever.
+
+## Questions? Comments?
+
+Send them along to
+the [Free Web Slide Show Alternatives (S5, S6, S9, Slidy And Friends) Forum/Mailing List](http://groups.google.com/group/webslideshow).
+Thanks!

+	<h3>研究目的</h3>
+	<p> 当研究室ではプログラムをコードセグメント、データセグメントという単位を用いて書くという手法を提案している。その手法を用いてプログラミングを行う言語として"CbC"の開発を行っており、これはCの下位の言語である。CbCにおいてコードセグメント間の移動はgoto文を用いた軽量継続によって行われ、これはTail Call Eliminationという最適化の強制によって実現される。</p>
+	<p>本研究過去に開発されたmicro-c,GCC版のコンパイラに続くLLVM/Clang上でのCbCコンパイラの開発を行う。</p>
+      </article>

+
+      <article>
+	<h3>conv1.c</h3>
+	<ul>
+	  <li>関数ポインタ宣言時に引数を合わせてあげないといけない (fastcc の条件)</li>
+	  <li>引数を省略すると内部では variadic function となる.</li>

+################################################################
+
+This sample hook safeguards topic branches that have been
+published from being rewound.
+
+The workflow assumed here is:
+
+ * Once a topic branch forks from "master", "master" is never
+   merged into it again (either directly or indirectly).
+
+ * Once a topic branch is fully cooked and merged into "master",
+   it is deleted.  If you need to build on top of it to correct
+   earlier mistakes, a new topic branch is created by forking at
+   the tip of the "master".  This is not strictly necessary, but
+   it makes it easier to keep your history simple.
+
+ * Whenever you need to test or publish your changes to topic
+   branches, merge them into "next" branch.
+
+The script, being an example, hardcodes the publish branch name
+to be "next", but it is trivial to make it configurable via
+$GIT_DIR/config mechanism.
+
+With this workflow, you would want to know:
+
+(1) ... if a topic branch has ever been merged to "next".  Young
+    topic branches can have stupid mistakes you would rather
+    clean up before publishing, and things that have not been
+    merged into other branches can be easily rebased without
+    affecting other people.  But once it is published, you would
+    not want to rewind it.
+
+(2) ... if a topic branch has been fully merged to "master".
+    Then you can delete it.  More importantly, you should not
+    build on top of it -- other people may already want to
+    change things related to the topic as patches against your
+    "master", so if you need further changes, it is better to
+    fork the topic (perhaps with the same name) afresh from the
+    tip of "master".
+
+Let's look at this example:
+
+		   o---o---o---o---o---o---o---o---o---o "next"
+		  /       /           /           /
+		 /   a---a---b A     /           /
+		/   /               /           /
+	       /   /   c---c---c---c B         /
+	      /   /   /             \         /
+	     /   /   /   b---b C     \       /
+	    /   /   /   /             \     /
+    ---o---o---o---o---o---o---o---o---o---o---o "master"
+
+
+A, B and C are topic branches.
+
+ * A has one fix since it was merged up to "next".
+
+ * B has finished.  It has been fully merged up to "master" and "next",
+   and is ready to be deleted.
+
+ * C has not merged to "next" at all.
+
+We would want to allow C to be rebased, refuse A, and encourage
+B to be deleted.
+
+To compute (1):
+
+	git rev-list ^master ^topic next
+	git rev-list ^master        next
+
+	if these match, topic has not merged in next at all.
+
+To compute (2):
+
+	git rev-list master..topic
+

+# S6 Format
+
+
+## Media Types 
+
+S6 supports out-of-the box three media types, that is, `projection`, `screen` and `print`:
+
+* `projection` => display one slide at-a-time; (use option `mode: slideshow`)
+* `screen`     => display all slides at-once on screen; (use option `mode: outline`) 
+* `print`      => print (and print preview)
+
+Note: Only the Opera browser has built-in support for `projection`.
+On other browsers S6 uses JavaScript to switch `projection` to `screen` on startup.
+
+
+## Structure, CSS Classes
+
+     .presentation
+       .slide
+         .step
+         .notes
+         .extra
+      
+### Core Classes
+
+`.presentation` (alias `.deck`, `.slides`)
+
+Top level class for all slides
+
+`.slide`
+
+Marks a slide
+
+`.step`  (alias `.incremental`, `.delayed`, `.action`, `.build`) 
+
+Marks a slide step. Shortcut Tip: If a list gets marked up with `.step`,
+all its children get marked up automatically.
+
+
+### Extras
+
+`.notes`  (alias `.note`, `.handout`)  
+
+Marks speaker notes.
+
+`.extra`
+
+Marks extra text for print only.
+
+
+
+## Styling and Slide Types
+
+### Slide Types/Layouts
+
+* fullscreen
+* hidden
+
+### Font Size
+
+Absolute:
+
+* xx-large
+* x-large
+* large
+* small
+* x-small
+* xx-small
+
+Relative:
+
+* larger
+* smaller

+# S6 Format for Plugins / Addons
+
+## Custom Events 
+
+S6 fires the following events (to let plugins/addons get hooks into the JavaScript machinery):
+
+* `slideshow.init`
+* `slideshow.start`
+* `slideshow.keys( key )`
+* `slideshow.debug.on`
+* `slideshow.debug.off`
+* `slideshow.change( from, to )`

+## What's S5? What's S6?
+
+Simple Standards-based Slide Show System (S5) is Eric Meyer's (of CSS fame) public domain
+(free, open source) slide show package inspired by Opera Show and others that works
+in all modern browsers without any plugin required
+because it includes its own slide show machinery in JavaScript.
+More [S5 Project Site »](http://meyerweb.com/eric/tools/s5)
+
+S6 started as a rewrite of S5 using the jQuery JavaScript library - offering
+easier to understand and easier to extend code. Add plugins, effects and more.
+Contributions welcome!
+
+## What's Slide Show (S9)? Slide Show Generator for S6 
+
+A Ruby gem that lets you create slide shows and author slides in plain text
+using a wiki-style markup language that's easy-to-write and easy-to-read
+and ships "out-of-the-gem" with S6 templates built-in.
+More [Slide Show (S9) Project Site »](http://slideshow-s9.github.io)
+
+
+## About, License
+
+The slide show (S6) scripts and templates are dedicated
+to the public domain. Use it as you please with no restrictions whatsoever.
+
+## Questions? Comments?
+
+Send them along to
+the [Free Web Slide Show Alternatives (S5, S6, S9, Slidy And Friends) Forum/Mailing List](http://groups.google.com/group/webslideshow).

+	<h3>研究目的</h3>
+	<p> 当研究室ではプログラムをコードセグメント、データセグメントという単位を用いて書くという手法を提案している。その手法を用いてプログラミングを行う言語として"CbC"の開発を行っており、これはCの下位の言語である。CbCにおいてコードセグメント間の移動はgoto文を用いた軽量継続によって行われ、これはTail Call Eliminationという最適化の強制によって実現される。</p>
+	<p>本研究過去に開発されたmicro-c,GCC版のコンパイラに続くLLVM/Clang上でのCbCコンパイラの開発を行う。</p>
