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. --- libffi/src/sh/ffi.c | 716 ++++++++++++++++++++++++++++++++++++++ libffi/src/sh/ffitarget.h | 49 +++ libffi/src/sh/sysv.S | 850 ++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 1615 insertions(+) create mode 100644 libffi/src/sh/ffi.c create mode 100644 libffi/src/sh/ffitarget.h create mode 100644 libffi/src/sh/sysv.S (limited to 'libffi/src/sh') diff --git a/libffi/src/sh/ffi.c b/libffi/src/sh/ffi.c new file mode 100644 index 000000000..69bd025fb --- /dev/null +++ b/libffi/src/sh/ffi.c @@ -0,0 +1,716 @@ +/* ----------------------------------------------------------------------- + ffi.c - Copyright (c) 2002, 2003, 2004, 2005, 2006, 2007, 2008 Kaz Kojima + Copyright (c) 2008 Red Hat, Inc. + + SuperH Foreign Function Interface + + Permission is hereby granted, free of charge, to any person obtaining + a copy of this software and associated documentation files (the + ``Software''), to deal in the Software without restriction, including + without limitation the rights to use, copy, modify, merge, publish, + distribute, sublicense, and/or sell copies of the Software, and to + permit persons to whom the Software is furnished to do so, subject to + the following conditions: + + The above copyright notice and this permission notice shall be included + in all copies or substantial portions of the Software. + + THE SOFTWARE IS PROVIDED ``AS IS'', WITHOUT WARRANTY OF ANY KIND, + EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF + MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND + NONINFRINGEMENT.
