NAME

       gc-analyze - Analyze Garbage Collector (GC) memory dumps

SYNOPSIS

       gc-analyze [OPTION] ... [file]

DESCRIPTION

       gc-analyze prints an analysis of a GC memory dump to standard out.

       The memory dumps may be created by calling "gnu.gcj.util.GCInfo.enumerate(String namePrefix)" from java code.  A memory dump will be
       created on an out of memory condition if "gnu.gcj.util.GCInfo.setOOMDump(String namePrefix)" is called before the out of memory occurs.

       Running this program will create two files: TestDump001 and TestDump001.bytes.

	       import gnu.gcj.util.*;
	       import java.util.*;

	       public class GCDumpTest
	       {
		   static public void main(String args[])
		   {
		       ArrayList<String> l = new ArrayList<String>(1000);

		       for (int i = 1; i < 1500; i++) {
			   l.add("This is string #" + i);
		       }
		       GCInfo.enumerate("TestDump");
		   }
	       }

       The memory dump may then be displayed by running:

	       gc-analyze -v TestDump001

OPTIONS

       --verbose
       -v  Verbose output.

       -p tool-prefix
	   Prefix added to the names of the nm and readelf commands.

       -d directory
	   Directory that contains the executable and shared libraries used when the dump was generated.

       --help
	   Print a help message, then exit.

       --version
	   Print version information, then exit.
