@@ -1,69 +0,0 @@ -The Java frontend translates Java bytecode (.class files) into LLVM -bytecode. This happens in two passes: a basic block building pass, -which creates and associates LLVM basic blocks to Java bytecode blocks -and a compilation pass, which builds the LLVM bytecode for the given -Java bytecode (in a sense: fill in the LLVM basic blocks with -instructions). - -Creating BasicBlocks --------------------- - -A pre-pass over the bytecode is performed that creates LLVM -BasicBlocks and associates them with their corresponding Java basic -block. This pass provides for a way to get the LLVM BasicBlock given a -bytecode index. It also provides a way to get the Java bytecode bounds -of the Java basic block given an LLVM BasicBlock. - -Modelling the operand stack ---------------------------- - -When compiling java bytecode to llvm we need to model the Java operand -stack, as this is the Java computation model. Some complication arises -though because longs and doubles are considered to take two slots in -the Java operand stack. - -In this frontend we don't use two slots on the operand stack for longs -or doubles. This simplyfies code generation for most instructions, but -untyped stack manipulation ones. There we need to know what is that -type of the poped items to figure out the final configuration of the -stack. - -The class2llvm compiler keeps a compile time stack of alloca's, which -loosly represent the slots of the java operand stack. These alloca's -are lazily created in the basic block they are first introduced. The -state of the stack is saved at the end of each basic block for its -successors to use it. Obviously the entry blocks gets an empty stack -as input. - -The type model is the obvious for the primitive types (int to int, -float to float, etc). For reference types the alloca is always of type -java.lang.Object*. - -Local variables ---------------- - -Similarly to the operand stack, the compiler keeps track of the local -variable slots. Again we use a single slot for doubles and longs. A -vector of sized to the max number of locals in the function is -initialized when a function is compiled and the alloca's are lazily -created on first use. - -Compilation ------------ - -In order to compile a Java method to an LLVM function we use a work -list of BasicBlocks to work through each basic block of the -function. This is required because for each java basic block we -compile we need to know the configuration of the operand stack and the -locals. This is knows iff at least one predecessor of this block is -compiled. - -So the work list is initialize with the entry basic block which has -known entry operand stack and locals. The operand stack is empty and -the locals contain the incoming arguments. When this basic block is -compiled the operand stack and locals are associated with all its -successors. For each successor this information is new (the operand -stack or locals was unknown) we add it to the work list. - -The above guarantees that all reachable java basic blocks are going to -be compiled.

@@ -1,47 +0,0 @@ -LLVM-TV: LLVM Transformation Visualizer -Written by: Misha Brukman, Tanya Brethour, and Brian Gaeke - -LLVM-TV is a tool that can be used to visualize the effects of transformations -written in the LLVM framework. Compilation units in LLVM have a simple, -hierarchical structure: a Module contains Functions, which contain BasicBlocks, -which contain Instructions. At the lowest level of this hierarchy, Instructions -may reference other BasicBlocks (with branches) or Functions (with calls), -making the control-flow graphs and call graphs explicit. Our first task is to -develop an interactive browser for these graphs and hierarchies. - -Our target audience is compiler developers working within the LLVM framework, -who are trying to understand and debug transformations. - -Currently, the visualization tool will not reflect dynamic updates -to the code; rather, it reflects the state of a compilation unit at -a single instant in time, between transformations. Future work should -extend this tool to reflect a dynamically updating view of the program as -a transformation is modifying the code. - -How to compile: - -1. You must have wxWindows installed on your system, and wx-config has to be - in your path. - - Make absolutely sure that wxwindows's configure picks up the same - C++ compiler that you're using for llvm. Otherwise, you may get - weird link errors when trying to link the llvm-tv tool. - -2. Configure and compile llvm-tv (you need an LLVM source and build trees): - -% cd path/to/llvm-tv -% ./configure --with-llvmsrc=[path] --with-llvmobj=[path] - If you're building in llvm/projects/llvm-tv, then you don't need - to specify these --with options. -% gmake - -Example of usage: - -% llvm-tv.exe & - The .exe is not a typo; this command starts up the visualizer in - the background using its wrapper script. -% opt-snap -debug -licm -snapshot -gcse -snapshot < bytecode-file.bc > /dev/null - This runs the llvm optimizer driver with the snapshot pass loaded, using - another wrapper script, and makes two snapshots, which should appear - in your visualizer. -

@@ -1,110 +0,0 @@ -Design of LLVM-TV ------------------ - -TVApplication implements the wxApp interface and is the launcher of LLVM-TV. -It is responsible for keeping track of all the windows, and the list of -available snapshots. It is also responsible for handling Unix signals sent to -the LLVM-TV process; this is the mechanism the LLVM optimizer uses for -communicating with LLVM-TV. - -TVFrame is responsible for the main LLVM-TV user interface - it sets up the -vertically-split main window having a tree of snapshots on the left -(TVTreeCtrl), and a tabbed view containing visualizers on the right -(TVNotebook). TVFrame is also responsible for the menu bar, and it is the first -object that deals with commands issued as a result of the user choosing menu -items. - -TVTreeItemData is the basic unit of visualization in LLVM-TV. It is also the -abstract superclass for all nodes that appear in the tree view on the left-hand -side of LLVM-TV's main window. The root of the tree is the Singleton -TVTreeRootItem, which is hidden (the user cannot select it) and has no -displayable data. The TVTreeRootItem contains TVTreeModuleItems, which point to -snapshots of LLVM Modules; the TVTreeModuleItems in turn contain -TVTreeFunctionItems, which point to snapshots of LLVM Functions within the -parent Modules. - -The TVHtmlWindow class is an ItemDisplayer that displays syntax-highlighted LLVM -assembly code for TVTreeItems (either Functions or Modules) in HTML format. - -A TVTreeItem uses an HTMLPrinter to display a Function or a Module in a -syntax-highlighted view. It also chooses a HTMLMarkup strategy class to decide -whether to use Cascading Style Sheets (CSS) or old-style "font" tags for syntax -highlighting of elements such as keywords, types, and basic-block names. -HTMLPrinter is a Visitor, implemented using the standard LLVM InstVisitor C++ -template. - -TVNotebook is responsible for implementing the tabbed interface which you see on -the right-hand side of the main window (the TVFrame). - -ItemDisplayer is the abstract superclass for objects that know how to visualize -LLVM Functions and/or Modules. ItemDisplayers can be displayed in tabs in the -TVNotebook view, or in their own windows (called PictureFrames). - -TVCodeViewer is the ItemDisplayer which implements the "interactive code view" -which highlights use-def chains. Each TVCodeViewer contains a TVCodeListCtrl, -which is responsible for the actual drawing of the list view, and which is where -most of the interesting stuff happens -- TVCodeViewer is essentially an Adapter -around TVCodeListCtrl to allow it to display itself either in a tab view or a -window. - -GraphDrawer is an abstract superclass for all graph-drawing visualizers. It -inherits the ItemDisplayer interface, so all GraphDrawers are also -ItemDisplayers. GraphDrawer simplifies the ItemDisplayer interface using the -Template Method pattern. Concrete GraphDrawers only need to be able to provide -an image object given a TVTreeItem; the abstract GraphDrawer class provides -for displaying the image in a convenient scrolling viewer (called a -PictureCanvas). - -CallGraphDrawer and CFGGraphDrawer are GraphDrawers for displaying the call -graph (for a Module) and the control-flow graph (for a Function), respectively. - -DSAGraphDrawer is an abstract class for Data Structure Graph viewers. -It implements GraphDrawer's Abstract Methods -drawFunctionGraph() and drawModuleGraph() as Template Methods which rely on -pure-virtual C++ methods that return the Pass object to write out the graph, -which is different for each of BUGraphDrawer, TDGraphDrawer, and -LocalGraphDrawer, as well as the filename to which they output the results of -their analysis. The functions createFunctionPass() and createModulePass() are -Factory Methods as they create passes of different classes that are subclasses -of FunctionPass or Pass, respectively. The algorithm for running the pass on a -Function or Module is shared among the 3 subclasses of DSAGraphDrawer. - -BUGraphDrawer, TDGraphDrawer, and LocalGraphDrawer are also ItemDisplayers, -which allows them to be displayed in tabs or in separate new windows. - - -Extending LLVM-TV ------------------ - -In order to add a new visualization to LLVM-TV, the programmer should add a new -concrete subclass of ItemDisplayer. The requirements for a new ItemDisplayer -subclass are: - -1) An ItemDisplayer must create and hold a wxWindows display widget (subclass of -wxWindow) to draw in. The widget should be of a type appropriate to the -visualization - for example, if you are displaying a list of things, use a -wxListCtrl; if you are displaying a tree, use a wxTreeCtrl. If you want to -display an image, you probably will want to create a subclass of GraphDrawer -instead (see below). When your getWindow() method is called, you should create -the display widget (if it has not already been created) and return a pointer to -it. - -2) An ItemDisplayer must respond to the displayItem(TVTreeItemData *) message by -updating its display widget to contain visual information about the given item. - -3) An ItemDisplayer must respond to the getDisplayTitle(TVTreeItemData *) -message by returning a string, suitable for a window or tab title, which -describes the visualization of the given item -- or if no item is passed in, a -string which describes the kind of visualization it generally performs (e.g., -"Dominator tree view of java.lang.System.arraycopy()" vs. "Dominator tree -view".) - -If you want to add a new visualization to LLVM-TV which *only* draws images and -allows the user to view them, you can subclass GraphDrawer. Instead of -requirements 1) and 2) above, a new subclass of GraphDrawer is required to -respond to the drawModuleGraph(Module *) and drawFunctionGraph(Function *) -messages by returning a wxImage object that contains an image representing the -LLVM item passed in. GraphDrawer will take care of displaying the image in a -scrolling canvas, either in a tab or a separate window. - -

Compilation units in LLVM have a simple, hierarchical -structure: -a Module contains Functions, which contain BasicBlocks, which contain -Instructions. The tree view will show you functions within the snapshot you are viewing.</p> - -<p> -From this screen shot, you can see that we have expanded a module revealing that it has several functions within it.</p> -<img src="images/llvmtv-expandmodule.jpg"> - -<p> -To the right of the tree view is a tabbed pane that allows you to easily browse -different views of the snapshot.</p> - -<b>TextView:</b><br> - -<p>The text view is a direct disassembly of the Module, showing the pointer size -of the target architecture for which it was compiled, endianness, the -user-defined types present in the module, global variables, and all function -definitions.</p> - -<img src="images/llvmtv-TextView.jpg"><p> - -<b>HTMLView:</b><br> - -<p>The HTML view is a syntax-highlighted view with LLVM keywords in blue, types -in green, and BasicBlock names in red. For brevity, the Module view does not -include the types and the functions are given as prototypes. External functions, -for which the Module has no code, are prepended with a `declare' keyword. Other -functions' code can be viewed by clicking on the appropriate node in the tree -list.</p> - -<img src="images/llvmtv-HTMLView.jpg"><p> - - -<b>DSGraph Views:</b><br> - -<p>LLVM has a powerful alias analysis framework and here we are showcasing its -novel Data Structure Analysis (DSA) algorithm. It has 3 components: the -Bottom-Up DSGraph, Top-down DSGraph, and Local DSGraph. These graphs show -points-to results analysis for global variables and other pointers in a -program. Here we see the results of a local data-structure analysis run:</p> - -<img src="images/llvmtv-LocalDSGraph.jpg"><p> - -<b>CodeView:</b><br> - -<p>Because LLVM is in SSA (Static Single Assignment) form, any use of a variable must -be preceded by exactly one definition. We can thus form def-use chains which -connect definitions of variables to their uses. The CodeView enables one to -click on any value and see where the uses of the variable occur, allowing a -visual way to inspect code. As a side effect, clicking on a BasicBlock entry -shows all users of the BasicBlock, which are branches that have the BasicBlock -as a target, thus showing how many incoming control-flow edges a block has.</p> - -<img src="images/llvmtv-CodeView.jpg"><p> - -<p>There are also more views under the View menu. Selecting one of these views will -open up a new window with that view in it. There are two new views that we have -not seen before: Call Graph view and Control Flow Graph view.</p> - -<img src="images/llvmtv-ViewMenu.jpg"><p> - -<b>Call Graph:</b><br> - -<p>The Call Graph shows the callers and callees of each function in the module. A graph of -functions, here each node represents a function and an arrow from node A to node -B means that function A calls function B at least once in its code.</p> - -<b>Control Flow Graph:</b><br> - -<p>The control flow graph displays graphically the control flow of the function, -identifying each basic block as a node and labeling all branches between blocks -as arrows.</p> - -<img src="images/llvmtv-ControlFlow.jpg"><p> - -Additionally, you can use the File menu to add more snapshots to the visualizer. -<br> -<img src="images/llvmtv-FileMenu.jpg"><p> - -<b>Add Module:</b><br> - -<p>This will add a given Module to the list of snapshots without having to run -opt-snap to deposit it into the snapshot collection. This is useful if you -want to compare different programs, instead of looking at multiple views -of the same program.</p> - -<b>Refresh:</b><br> - -<p>This option will re-read the snapshot collection directory to see if any new -Modules have been added manually by the user (by copying directly through the -filesystem).</p> - -<h4>Snapshots and Signaling:</h4> - -<p> -A neat feature of the LLVM Visualization tool is that the GUI will automatically -refresh the snapshot listing when opt-snap signals that a new snapshot has been -generated.
