From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- .../classpath/vm/reference/java/lang/VMClass.java | 469 ++++++++++++++++++ .../vm/reference/java/lang/VMClassLoader.java | 431 ++++++++++++++++ .../vm/reference/java/lang/VMCompiler.java | 112 +++++ .../classpath/vm/reference/java/lang/VMDouble.java | 115 +++++ .../classpath/vm/reference/java/lang/VMFloat.java | 118 +++++ .../classpath/vm/reference/java/lang/VMMath.java | 493 ++++++++++++++++++ .../classpath/vm/reference/java/lang/VMObject.java | 105 ++++ .../vm/reference/java/lang/VMProcess.java | 402 +++++++++++++++ .../vm/reference/java/lang/VMRuntime.java | 192 +++++++ .../classpath/vm/reference/java/lang/VMString.java | 91 ++++ .../classpath/vm/reference/java/lang/VMSystem.java | 220 +++++++++ .../classpath/vm/reference/java/lang/VMThread.java | 461 +++++++++++++++++ .../vm/reference/java/lang/VMThrowable.java | 82 +++ .../java/lang/management/VMManagementFactory.java | 75 +++ .../vm/reference/java/lang/reflect/VMArray.java | 65 +++ .../reference/java/lang/reflect/VMConstructor.java | 169 +++++++ .../vm/reference/java/lang/reflect/VMField.java | 549 +++++++++++++++++++++ .../vm/reference/java/lang/reflect/VMMethod.java | 208 ++++++++ .../vm/reference/java/lang/reflect/VMProxy.java | 135 +++++ 19 files changed, 4492 insertions(+) create mode 100644 libjava/classpath/vm/reference/java/lang/VMClass.java create mode 100644 libjava/classpath/vm/reference/java/lang/VMClassLoader.java create mode 100644 libjava/classpath/vm/reference/java/lang/VMCompiler.java create mode 100644 libjava/classpath/vm/reference/java/lang/VMDouble.java create mode 100644 libjava/classpath/vm/reference/java/lang/VMFloat.java create mode 100644 libjava/classpath/vm/reference/java/lang/VMMath.java create mode 100644 libjava/classpath/vm/reference/java/lang/VMObject.java create mode 100644 libjava/classpath/vm/reference/java/lang/VMProcess.java create mode 100644 libjava/classpath/vm/reference/java/lang/VMRuntime.java create mode 100644 libjava/classpath/vm/reference/java/lang/VMString.java create mode 100644 libjava/classpath/vm/reference/java/lang/VMSystem.java create mode 100644 libjava/classpath/vm/reference/java/lang/VMThread.java create mode 100644 libjava/classpath/vm/reference/java/lang/VMThrowable.java create mode 100644 libjava/classpath/vm/reference/java/lang/management/VMManagementFactory.java create mode 100644 libjava/classpath/vm/reference/java/lang/reflect/VMArray.java create mode 100644 libjava/classpath/vm/reference/java/lang/reflect/VMConstructor.java create mode 100644 libjava/classpath/vm/reference/java/lang/reflect/VMField.java create mode 100644 libjava/classpath/vm/reference/java/lang/reflect/VMMethod.java create mode 100644 libjava/classpath/vm/reference/java/lang/reflect/VMProxy.java (limited to 'libjava/classpath/vm/reference/java/lang') diff --git a/libjava/classpath/vm/reference/java/lang/VMClass.java b/libjava/classpath/vm/reference/java/lang/VMClass.java new file mode 100644 index 000000000..a0091c073 --- /dev/null +++ b/libjava/classpath/vm/reference/java/lang/VMClass.java @@ -0,0 +1,469 @@ +/* VMClass.java -- VM Specific Class methods + Copyright (C) 2003, 2004, 2005, 2006 Free Software Foundation + +This file is part of GNU Classpath. + +GNU Classpath is free software; you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation; either version 2, or (at your option) +any later version. + +GNU Classpath is distributed in the hope that it will be useful, but +WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
