@c man begin SYNOPSIS gc-analyze
@command{gc-analyze} [@option{OPTION}] @dots{} [@var{file}]
@ignore
[@option{-v}]
[@option{--verbose}]
[@option{-p} @var{tool-prefix}]
[@option{-d} @var{directory}]
[@option{--version}]
[@option{--help}]
@end ignore
@c man end
@c man begin DESCRIPTION gc-analyze
@command{gc-analyze} prints an analysis of a GC memory dump to
standard out.
The memory dumps may be created by calling
@code{gnu.gcj.util.GCInfo.enumerate(String namePrefix)} from java
code. A memory dump will be created on an out of memory condition if
@code{gnu.gcj.util.GCInfo.setOOMDump(String namePrefix)} is called
before the out of memory occurs.
Running this program will create two files: @file{TestDump001} and
@file{TestDump001.bytes}.
@example
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");
@}
@}
@end example
The memory dump may then be displayed by running:
@example
gc-analyze -v TestDump001
@end example
@c FIXME: Add real information here.
@c This really isn't much more than the --help output.
@c man end
@c man begin OPTIONS gc-analyze
@table @gcctabopt
@item --verbose
@itemx -v
Verbose output.
@item -p @var{tool-prefix}
Prefix added to the names of the @command{nm} and @command{readelf} commands.
@item -d @var{directory}
Directory that contains the executable and shared libraries used when
the dump was generated.
@item --help
Print a help message, then exit.
@item --version
Print version information, then exit.
