From 043613fbb199e2c4fdd12c2c9a1785db9b0c45fa Mon Sep 17 00:00:00 2001 From: Matthew Bentham Date: Tue, 30 May 2023 16:43:14 +0000 Subject: Break up Utils.h a bit to reduce unused code being included everywhere Move some maths-related things from Utils.h to new Math.h header in utils/math. Move some routines used for Tensor shape validation to Validate.h Change-Id: I8ce89fe03ec3ae1b61d1a80c282b8b91eea0cfb3 Signed-off-by: Matthew Bentham Reviewed-on: https://eu-gerrit-1.euhpc.arm.com/c/VisualCompute/ComputeLibrary/+/524783 Reviewed-by: Gian Marco Iodice Tested-by: Viet-Hoa Do Reviewed-on: https://review.mlplatform.org/c/ml/ComputeLibrary/+/9743 Benchmark: Arm Jenkins Tested-by: Arm Jenkins Reviewed-by: Jakub Sujak Comments-Addressed: Arm Jenkins --- arm_compute/core/utils/math/Math.h | 71 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 71 insertions(+) create mode 100644 arm_compute/core/utils/math/Math.h (limited to 'arm_compute/core/utils') diff --git a/arm_compute/core/utils/math/Math.h b/arm_compute/core/utils/math/Math.h new file mode 100644 index 0000000000..c1dce7ff08 --- /dev/null +++ b/arm_compute/core/utils/math/Math.h @@ -0,0 +1,71 @@ +/* + * Copyright (c) 2017-2018, 2023 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.
