| 26 * Gamma (Hotspot internal engineering test) launcher based on 6.0u22 JDK, | |
| 27 * search "GAMMA" for gamma specific changes. | |
| 28 * | |
| 29 * GAMMA: gamma launcher is much simpler than regular java launcher in that | |
| 30 * JVM is either statically linked in or it is installed in the | |
| 31 * same directory where the launcher exists, so we don't have to | |
| 32 * worry about choosing the right JVM based on command line flag, jar | |
| 33 * file and/or ergonomics. Intead of removing unused logic from source | |
| 34 * they are commented out with #ifndef GAMMA, hopefully it'll be easier | |
| 35 * to maintain this file in sync with regular JDK launcher. | |
| 36 */ | |
| 37 | |
| 38 /* | |
| 39 * Shared source for 'java' command line tool. | |
| 40 * | |
| 41 * If JAVA_ARGS is defined, then acts as a launcher for applications. For | |
| 42 * instance, the JDK command line tools such as javac and javadoc (see | |
| 43 * makefiles for more details) are built with this program. Any arguments | |
| 44 * prefixed with '-J' will be passed directly to the 'java' command. | |
| 45 */ | |
| 46 | |
| 47 #ifdef GAMMA | |
| 48 # ifdef JAVA_ARGS | |
| 49 # error Do NOT define JAVA_ARGS when building gamma launcher | |

| 56 /* | |
| 57 * One job of the launcher is to remove command line options which the | |
| 58 * vm does not understand and will not process. These options include | |
| 59 * options which select which style of vm is run (e.g. -client and | |
| 60 * -server) as well as options which select the data model to use. | |
| 61 * Additionally, for tools which invoke an underlying vm "-J-foo" | |
| 62 * options are turned into "-foo" options to the vm. This option | |
| 63 * filtering is handled in a number of places in the launcher, some of | |
| 64 * it in machine-dependent code. In this file, the function | |
| 65 * CheckJVMType removes vm style options and TranslateApplicationArgs | |
| 66 * removes "-J" prefixes. On unix platforms, the | |
| 67 * CreateExecutionEnvironment function from the unix java_md.c file | |
| 68 * processes and removes -d<n> options. However, in case | |
| 69 * CreateExecutionEnvironment does not need to exec because | |
| 70 * LD_LIBRARY_PATH is set acceptably and the data model does not need | |
| 71 * to be changed, ParseArguments will screen out the redundant -d<n> | |
| 72 * options and prevent them from being passed to the vm; this is done | |
| 73 * by using the machine-dependent call | |
| 74 * RemovableMachineDependentOption. | |

| 96 * The following environment variable is used to influence the behavior | |
| 97 * of the jre exec'd through the SelectVersion routine. The command line | |
| 98 * options which specify the version are not passed to the exec'd version, | |
| 99 * because that jre may be an older version which wouldn't recognize them. | |
| 100 * This environment variable is known to this (and later) version and serves | |
| 101 * to suppress the version selection code. This is not only for efficiency, | |
| 102 * but also for correctness, since any command line options have been | |
| 103 * removed which would cause any value found in the manifest to be used. | |
| 104 * This would be incorrect because the command line options are defined | |
| 105 * to take precedence. | |

| 108 * name from within the executable jar file (if any). This is strictly a | |
| 109 * performance enhancement to avoid re-reading the jar file manifest. | |
| 110 * | |

| 112 * the program image remain relatively small until after SelectVersion | |
| 113 * CreateExecutionEnvironment have finished their possibly recursive | |
| 114 * processing. Watch everything, but resist all temptations to use Java | |

| 1834 * flag := "-" identifier | |
| 1835 * | |
| 1836 * The semantics are that when someone specifies a flag on the command line: | |
| 1837 * - if the flag appears on a knownLine, then the identifier is used as | |
| 1838 * the name of the directory holding the JVM library (the name of the JVM). | |
| 1839 * - if the flag appears as the first flag on an aliasLine, the identifier | |
| 1840 * of the second flag is used as the name of the JVM. | |
| 1841 * - if the flag appears on a warnLine, the identifier is used as the | |
| 1842 * name of the JVM, but a warning is generated. | |
| 1843 * - if the flag appears on an ignoreLine, the identifier is recognized as the | |
| 1844 * name of a JVM, but the identifier is ignored and the default vm used | |
| 1845 * - if the flag appears on an errorLine, an error is generated. | |
| 1846 * - if the flag appears as the first flag on a predicateLine, and | |
| 1847 * the machine on which you are running passes the predicate indicated, | |
| 1848 * then the identifier of the second flag is used as the name of the JVM, | |
| 1849 * otherwise the identifier of the first flag is used as the name of the JVM. | |
| 1850 * If no flag is given on the command line, the first vmLine of the jvm.cfg | |
| 1851 * file determines the name of the JVM. | |
| 1852 * PredicateLines are only interpreted on first vmLine of a jvm.cfg file, | |
| 1853 * since they only make sense if someone hasn't specified the name of the | |
| 1854 * JVM on the command line. | |
