NAME
cacao - a Java just-in-time compilerSYNOPSIS
cacao [ options ] classname [ argument ... ]cacao [ options ] -jar file.jar [ argument ... ]
DESCRIPTION
The method main of the class classname is executed. Method main must have the signature public static void main(String[] argv). The program arguments are passed to method main in the string array argv. The environment variable CLASSPATH must contain the directory of the Java class files.OPTIONS
Currently recognized options are:- -classpath path
- Set the search path for user-defined class files. Usually the environment variable CLASSPATH specifies the search path, but this option overrides the value of the environment variable. path may be a colon-separated list of directories and .jar files.
- -cp path
- Equivalent to -classpath path.
- -Dproperty=value
- Assign a value to an entry of the system property list.
- -verbose[:class|gc|jni]
- Enable specific verbose output.
- -version
- Print product version and exit.
- -fullversion
- Print jpackage-compatible product version and exit.
- -showversion
- Print product version and continue.
- -help, -?
- Print this help message and exit.
- -X
- Print help on non-standard Java options.
NON-STANDARD OPTIONS
Currently recognized options are:- -Xbootclasspath/a:path
- Append path to the search path of the bootstrap loader.
- -Xbootclasspath/p:path
- Prepend path to the search path of the bootstrap loader.
- -Xbootclasspath:path
- Set the search path of the bootstrap loader to path. path is a list of .zip files, .jar files, or directories, separated by :.
- -Xint
- Interpreter mode execution.
- -Xjit
- JIT mode execution (default).
- -Xmssize
- Set the initial size of the heap (default: 2MB).
- -Xmxsize
- Set the maximum size of the heap (default: 64MB).
- -Xsssize
- Set the thread stack size (default: 128kB).
- -all
- Compile all methods, no execution.
- -cb
- Disable array bounds checks.
- -cs
- Disable synchronization.
- -l
- Don't start the class after loading.
- -liberalutf
- Don't warn about overlong UTF-8 sequences.
- -log logfile
- Specifies the logfile. Default is stdout.
- -lsra
- Use linear scan register allocation.
- -m method
- Compile only a specific method.
- -noverify
- Turn off bytecode verification and other verifier checks.
- -sig signature
- Specify signature for the method given by the -m option.
- -softnull
- Use software nullpointer check.
- -stat
- Print detailed compiler statistics.
- -time
- Gives statistics about run time after the program has completed.
- -v
- Print state information.
DEBUGGING OPTIONS
The following options are useful for debugging cacao:
- -sa
- Show a disassembled listing of the generated code.
- -sc
- Show the constant pool.
- -sd
- Show data segment listing.
- -se
- Show disassembled exception stubs (only with -sa).
- -si
- Show intermediate representation.
- -sm
- Show class fields and methods.
- -sn
- Show disassembled native stubs.
- -su
- Show the internal utf hash.
- -verbose
- Print more information.
- -verbosecall
- Trace method calls.
- -verboseexception
- Trace exceptions and stack unwinding.
- -verbosegc
- Print a message for each garbage collection.
EXPERIMENTAL OPTIONS
- -eager
- Perform eager class loading and linking.
- -ie
- Inline methods with exceptions.
- -in
- Activate inlining of methods.
- -io
- Inline methods of foreign classes.
- -ip
- Optimize argument renaming when inlining.
- -iv
- Inline virtual methods (uses/turns -rt option on).
- -oloop
- Optimize array accesses in loops.
- -rt
- Use rapid type analysis.
- -vta
- Use variable type analysis.
- -xta
- Use X type analysis.
ENVIRONMENT VARIABLES
- CLASSPATH
- A colon-separated list of directories and .jar files to search for user-defined classes.
- BOOTCLASSPATH
- A colon-separated list of directories and .jar files searched by the bootstrap loader.
