From a63c2657c94913d72b3cd388730d61edcb09fc69 Mon Sep 17 00:00:00 2001 From: tromey Date: Sat, 16 Jul 2005 01:27:14 +0000 Subject: Major merge with Classpath. Removed many duplicate files. * HACKING: Updated.x * classpath: Imported new directory. * standard.omit: New file. * Makefile.in, aclocal.m4, configure: Rebuilt. * sources.am: New file. * configure.ac: Run Classpath configure script. Moved code around to support. Disable xlib AWT peers (temporarily). * Makefile.am (SUBDIRS): Added 'classpath' (JAVAC): Removed. (AM_CPPFLAGS): Added more -I options. (BOOTCLASSPATH): Simplified. Completely redid how sources are built. Include sources.am. * include/Makefile.am (tool_include__HEADERS): Removed jni.h. * include/jni.h: Removed (in Classpath). * scripts/classes.pl: Updated to look at built classes. * scripts/makemake.tcl: New file. * testsuite/libjava.jni/jni.exp (gcj_jni_compile_c_to_so): Added -I options. (gcj_jni_invocation_compile_c_to_binary): Likewise. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@102082 138bc75d-0d04-0410-961f-82ee72b054a4 --- libjava/gnu/java/lang/reflect/TypeSignature.java | 288 ----------------------- 1 file changed, 288 deletions(-) delete mode 100644 libjava/gnu/java/lang/reflect/TypeSignature.java (limited to 'libjava/gnu/java/lang/reflect') diff --git a/libjava/gnu/java/lang/reflect/TypeSignature.java b/libjava/gnu/java/lang/reflect/TypeSignature.java deleted file mode 100644 index 842e5bdf0f0..00000000000 --- a/libjava/gnu/java/lang/reflect/TypeSignature.java +++ /dev/null @@ -1,288 +0,0 @@ -/* TypeSignature.java -- Class used to compute type signatures - Copyright (C) 1998, 2000, 2002 Free Software Foundation, Inc. - -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.
