option
This command can be used to pass a JIT compilation option to the specified method in place of the last argument (\fIoption\fR)\&. The compilation option is set at the end, after the method name\&. For example, to enable the \f3BlockLayoutByFrequency\fR option for the \f3append()\fR method of the \f3StringBuffer\fR class, use the following:
You can specify multiple compilation options, separated by commas or spaces\&.

Each line in the command file represents a command, a class name, and a method name for which the command is used\&. For example, this line prints assembly code for the \f3toString()\fR method of the \f3String\fR class:

Sets the file from which compiler commands are read\&. By default, the \f3\&.hotspot_compiler\fR file is used to store commands performed by the JVM compiler\&.
Sets the list of methods (separated by commas) to which compilation should be restricted\&. Only the specified methods will be compiled\&. Specify each method with the full class name (including the packages and subpackages)\&. For example, to compile only the \f3length()\fR method of the \f3String\fR class and the \f3size()\fR method of the \f3List\fR class, use the following:
Each line in the command file represents a command, a class name, and a method name for which the command is used (all three parts are separated by spaces)\&. For example, this line prints assembly code for the \f3toString()\fR method of the \f3String\fR class:
Note that the full class name is specified, including all packages and subpackages separated by a slash (\f3/\fR)\&. For easier cut and paste operations, it is also possible to use the method name format produced by the \f3-XX:+PrintCompilation\fR and \f3-XX:+LogCompilation\fR options:

To add commands to the beginning of the \f3\&.hotspot_compiler\fR file, use the \f3-XX:CompileCommand\fR option\&. Note how the syntax of the command file is different from the syntax of the argument for the \f3-XX:CompileCommand\fR option\&. The commas and periods in the argument are aliases for spaces in the command file, making it easier to pass compiler commands through a shell\&. Although it is possible to pass arguments to \f3-XX:CompileCommand\fR with the same syntax as that used in the command file, you would have to enclose the string argument in quotation marks\&.
Although wildcards are not supported, you can specify only the class or package name to compile all methods in that class or package, as well as specify just the method to compile methods with this name in any class:
