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. --- .../gcc.target/x86_64/abi/avx/abi-avx.exp | 61 +++++++ gcc/testsuite/gcc.target/x86_64/abi/avx/args.h | 180 +++++++++++++++++++++ .../gcc.target/x86_64/abi/avx/asm-support.S | 82 ++++++++++ .../gcc.target/x86_64/abi/avx/avx-check.h | 28 ++++ .../x86_64/abi/avx/test_m256_returning.c | 32 ++++ .../gcc.target/x86_64/abi/avx/test_passing_m256.c | 168 +++++++++++++++++++ .../x86_64/abi/avx/test_passing_structs.c | 61 +++++++ .../x86_64/abi/avx/test_passing_unions.c | 143 ++++++++++++++++ 8 files changed, 755 insertions(+) create mode 100644 gcc/testsuite/gcc.target/x86_64/abi/avx/abi-avx.exp create mode 100644 gcc/testsuite/gcc.target/x86_64/abi/avx/args.h create mode 100644 gcc/testsuite/gcc.target/x86_64/abi/avx/asm-support.S create mode 100644 gcc/testsuite/gcc.target/x86_64/abi/avx/avx-check.h create mode 100644 gcc/testsuite/gcc.target/x86_64/abi/avx/test_m256_returning.c create mode 100644 gcc/testsuite/gcc.target/x86_64/abi/avx/test_passing_m256.c create mode 100644 gcc/testsuite/gcc.target/x86_64/abi/avx/test_passing_structs.c create mode 100644 gcc/testsuite/gcc.target/x86_64/abi/avx/test_passing_unions.c (limited to 'gcc/testsuite/gcc.target/x86_64/abi/avx') diff --git a/gcc/testsuite/gcc.target/x86_64/abi/avx/abi-avx.exp b/gcc/testsuite/gcc.target/x86_64/abi/avx/abi-avx.exp new file mode 100644 index 000000000..a509f2b08 --- /dev/null +++ b/gcc/testsuite/gcc.target/x86_64/abi/avx/abi-avx.exp @@ -0,0 +1,61 @@ +# Copyright (C) 2009, 2010 Free Software Foundation, Inc. + +# This program 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 3 of the License, or +# (at your option) any later version. +# +# This program 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.
