Fixed the stateBefore of invokes and monitorenter instructions to include the arguments of the instruction.
This is necessary to ensure correct continuation in the interpreter when the stateBefore is used as a deoptimization point.

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN"> <html> <head> <title>Hotspot SA User Interface Notes</title> </head> <body> <h1>Hotspot SA User Interface Notes</h1> <h2>Workspace and Building</h2> <p> All the source code for the Serviceability Agent is in <code>src/share/vm/agent</code> in the HotSport workspace <code>/net/jano.sfbay/export/disk05/hotspot/ws/1.4/sa_baseline</code> <p> You can build the project by typing <code>gnumake</code> in the <code>src/share/vm/agent</code> directory. <p> You can also use the default build target using the Ant build file (build.xml). You can download Ant from <a href="http://jakarta.apache.org/ant">http://jakarta.apache.org/ant</a>. Documentation for Ant can be found at <a href="http://jakarta.apache.org/ant/manual/index.html">http://jakarta.apache.org/ant/manual/index.html</a> <h2>Running the project</h2> <ul> <li><code>java -cp classes sun.jvm.hotspot.HSDB</code> <li><code>java -cp classes sun.jvm.hotspot.bugspot.Main</code> </ul> <h2>Feedback</h2> <p> Refactoring of package hierarchy. All user interface components should be in the ui package. Perhaps: sun.jvm.hotspot.ui.hsdb.Main for the HSDB and sun.jvm.hotspot.ui.bugspot.Main for BugSpot. <p> The src\share\vm\agent area seems like a workspace so it should be organized like one. In particular, I'd like to suggest the following directory layout:<br> <ul> <li>src: All sources that are curently under the sun directory. <li>classes: compiled class files. <li>lib: Resources like images, icons and jar files. <li>docs: Documentation <li>deploy: distribution bundles for Java Web Start. </ul> <p> Seems like there is a lot of redundant functionality. Between the HSDB and BugSpot. Perhaps this can be consolidated with a <code>javax.swing.Actions</code> architecture. <h2>Tasklist</h2> <p> <b>Stack memory pane</b>: It's one of the more useful JVM debugging tools in the SA. However, it doesn't support any interaction with the text; the Memory Panel in BugSpot was written afterward (with help from Shannon) and implements proper selection, scrolling, and drag-and-drop, but no annotations. I'm not sure how to integrate the annotations with the JTable that's being used for the memory view; if you have suggestions here please let me know. <p> <b>Integrations with the NetBeans architecture (plug in).</b> See the <a href="http://openide.netbeans.org">Netbeans Open APIs homepage</a> <p> HSDB: Object Histogram. Column sizes should be sized according the the contents. i.e, The size and count columns should be narrow enought to handle the largest window. Since there is a lot of data, sorting and searching should be implemented. <p> <h2>Log</h2> <i>Last modified: Tue Feb 05 19:15:12 Pacific Standard Time 2002</i> <p> sun.jvm.hotspot.oops.ObjectHistogram should be the underlying data structure for the TableModels. It shouldnt bother with sorting the data - the table model should do that. It should implement these methods: <pre> public int getSize() public ObjectHistogramElement getElementAt(int row); </pre> <p> ObjectHistogramElement should return the String that represents the third column <hr> <address><a href="mailto:mark.davidson@sun.com">Mark Davidson</a></address> <!-- Created: Mon Jan 28 14:33:47 Pacific Standard Time 2002 --> <!-- hhmts start --> Last modified: Tue Feb 05 20:05:13 Pacific Standard Time 2002 <!-- hhmts end --> </body> </html>
