From 7891a73ef36f4ad7b71069b3c57694f85bb79454 Mon Sep 17 00:00:00 2001 From: Georgios Pinitas Date: Fri, 20 Aug 2021 21:39:25 +0100 Subject: Move CPU/GPU files from Core/Runtime to the respective backend folders Legacy structure contained two libraries core/runtime with two backends in each. We reduce the core/runtime libraries to a single library thus merging the backend files Signed-off-by: Georgios Pinitas Change-Id: I69545765fe7a730368105cdbd067d3135ec7a174 Reviewed-on: https://review.mlplatform.org/c/ml/ComputeLibrary/+/6155 Comments-Addressed: Arm Jenkins Reviewed-by: Michele Di Giorgio Tested-by: Arm Jenkins --- src/cpu/kernels/sub/neon/list.h | 159 +++++++++++++++++++ src/cpu/kernels/sub/neon/qasymm8.cpp | 230 ++++++++++++++++++++++++++++ src/cpu/kernels/sub/neon/qasymm8_signed.cpp | 229 +++++++++++++++++++++++++++ src/cpu/kernels/sub/neon/qsymm16.cpp | 201 ++++++++++++++++++++++++ 4 files changed, 819 insertions(+) create mode 100644 src/cpu/kernels/sub/neon/list.h create mode 100644 src/cpu/kernels/sub/neon/qasymm8.cpp create mode 100644 src/cpu/kernels/sub/neon/qasymm8_signed.cpp create mode 100644 src/cpu/kernels/sub/neon/qsymm16.cpp (limited to 'src/cpu/kernels/sub') diff --git a/src/cpu/kernels/sub/neon/list.h b/src/cpu/kernels/sub/neon/list.h new file mode 100644 index 0000000000..ac1346001a --- /dev/null +++ b/src/cpu/kernels/sub/neon/list.h @@ -0,0 +1,159 @@ +/* + * Copyright (c) 2021 Arm Limited. + * + * SPDX-License-Identifier: MIT + * + * 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.
