25 DESCRIPTION
|
|
|
26
|
|
|
27 This is replacement for CompileTheWorld (CTW) written on java. Its purpose is
|
|
|
28 to make possible the use of CTW in product builds.
|
|
|
29
|
|
|
30 DEPENDENCES
|
|
|
31
|
|
|
32 The tool depends on Whitebox API. Assumed, that the sources of whitebox are
|
|
|
33 located in '../whitebox' directory.
|
|
|
34
|
|
|
35 BUILDING
|
|
|
36
|
|
|
37 Simple way to build, just type 'make'.
|
|
|
38
|
|
|
39 Makefile uses environment variables 'ALT_BOOTDIR', 'BOOTDIR' as root-dir of jdk
|
|
|
40 that will be used for compilation and creating jar.
|
|
|
41
|
|
|
42 On successful building 'ctw.jar' will be created.
|
|
|
43
|
|
|
44 RUNNING
|
|
|
45
|
|
|
46 Since the tool uses WhiteBox API, options 'UnlockDiagnosticVMOptions' and
|
|
|
47 'WhiteBoxAPI' should be specified, and 'wb.jar' should be added to
|
|
|
48 boot-classpath:
|
|
|
49 $ java -XX:+UnlockDiagnosticVMOptions -XX:+WhiteBoxAPI -Xbootclasspath/a:wb.jar -jar ctw.jar
|
|
|
50
|
|
|
51 Arguments can be paths to '.jar, '.zip', '.lst' files or directories with
|
|
|
52 classes, that define which classes will be compiled:
|
|
|
53 - '.jar', '.zip' files and directories are interpreted like in classpath
|
|
|
54 (including '<dir>/*' syntax)
|
|
|
55 - '.lst' files -- files with class names (in java notation) to compile.
|
|
|
56 CTW will try to find these classes with default class loader, so they should
|
|
|
57 be located in classpath.
|
|
|
58
|
|
|
59 Without arguments it would work as old version of CTW: all classes in
|
|
|
60 boot-classpath will be compiled, excluding classes in 'rt.jar' if 'rt.jar' isn't
|
|
|
61 first in boot-classpath.
|
|
|
62
|
|
|
63 Due CTW's flags also are not available in product builds, the tool uses
|
|
|
64 properties with the same names:
|
|
|
65 - 'CompileTheWorldPreloadClasses' -- type:boolean, default:true, description:
|
|
|
66 Preload all classes used by a class before start loading
|
|
|
67 - 'CompileTheWorldStartAt' -- type:long, default:1, description: First class
|
|
|
68 to consider
|
|
|
69 - 'CompileTheWorldStopAt' -- type:long, default:Long.MAX_VALUE, description:
|
|
|
70 Last class to consider
|
|
|
71
|
|
|
72 Also it uses additional properties:
|
|
|
73 - 'sun.hotspot.tools.ctw.verbose' -- type:boolean, default:false,
|
|
|
74 description: Verbose output, adds additional information about compilation
|
|
|
75 - 'sun.hotspot.tools.ctw.logfile' -- type:string, default:null,
|
|
|
76 description: Path to logfile, if it's null, cout will be used.
|
|
|
77
|
|
|
78 EXAMPLES
|
|
|
79
|
|
|
80 compile classes from 'rt.jar':
|
|
|
81 $ java -XX:+UnlockDiagnosticVMOptions -XX:+WhiteBoxAPI -Xbootclasspath/a:wb.jar -jar ctw.jar ${JAVA_HOME}/jre/lib/rt.jar
|
|
|
82
|
|
|
83 compile classes from all '.jar' in './testjars' directory:
|
|
|
84 $ java -XX:+UnlockDiagnosticVMOptions -XX:+WhiteBoxAPI -Xbootclasspath/a:wb.jar -jar ctw.jar ./testjars/*
|
|
|
85
|
|
|
86 compile classes from './build/classes' directory:
|
|
|
87 $ java -XX:+UnlockDiagnosticVMOptions -XX:+WhiteBoxAPI -Xbootclasspath/a:wb.jar -jar ctw.jar ./build/classes
|
|
|
88
|
|
|
89 compile only java.lang.String, java.lang.Object classes:
|
|
|
90 $ echo java.lang.String > classes.lst
|
|
|
91 $ echo java.lang.Object >> classes.lst
|
|
|
92 $ java -XX:+UnlockDiagnosticVMOptions -XX:+WhiteBoxAPI -Xbootclasspath/a:wb.jar -jar ctw.jar classes.lst
