From 2b4b65b6cd15337b304f4cd2a11dadb265cff8d7 Mon Sep 17 00:00:00 2001 From: Bernhard Manfred Gruber Date: Sun, 7 Mar 2021 17:44:36 +0100 Subject: [PATCH 1/8] support sub arrays of dynamic size as field type * allow dynamic field types in the record dimension * add specializations to most of the core functions * add llama::dynamic to signal a dynamic array member in a RecordCoord * extend VirtualRecord to allow holding dynamic indices * extend blobNrAndOffset to allow for additional dynamic indices * add OffsetTable mapping * add customization allowing to dump OffsetTable mappings * add a few unit tests --- examples/bufferguard/bufferguard.cpp | 8 +- include/llama/Concepts.hpp | 2 +- include/llama/Core.hpp | 53 ++++ include/llama/DumpMapping.hpp | 22 +- include/llama/Proofs.hpp | 6 +- include/llama/RecordCoord.hpp | 3 + include/llama/View.hpp | 28 +- include/llama/VirtualRecord.hpp | 92 ++++++- include/llama/llama.hpp | 1 + include/llama/mapping/AoS.hpp | 8 +- include/llama/mapping/AoSoA.hpp | 8 +- include/llama/mapping/Bytesplit.hpp | 18 +- include/llama/mapping/Heatmap.hpp | 10 +- include/llama/mapping/OffsetTable.hpp | 361 +++++++++++++++++++++++++ include/llama/mapping/One.hpp | 8 +- include/llama/mapping/SoA.hpp | 12 +- include/llama/mapping/Split.hpp | 13 +- include/llama/mapping/Trace.hpp | 10 +- include/llama/mapping/tree/Mapping.hpp | 8 +- tests/computedprop.cpp | 15 +- tests/core.cpp | 29 +- tests/mapping.cpp | 2 +- tests/proofs.cpp | 16 +- tests/recorddimension.cpp | 217 +++++++++++++++ tests/virtualrecord.cpp | 2 +- 25 files changed, 876 insertions(+), 76 deletions(-) create mode 100644 include/llama/mapping/OffsetTable.hpp diff --git a/examples/bufferguard/bufferguard.cpp b/examples/bufferguard/bufferguard.cpp index eec01096f9..d9c20a1960 100644 --- a/examples/bufferguard/bufferguard.cpp +++ b/examples/bufferguard/bufferguard.cpp @@ -68,9 +68,11 @@ struct GuardMapping2D : llama::ArrayExtentsDynamic<2> std::abort(); } - template - constexpr auto blobNrAndOffset(ArrayIndex ai, llama::RecordCoord rc = {}) const - -> llama::NrAndOffset + template + constexpr auto blobNrAndOffset( + ArrayIndex ai, + llama::Array = {}, + llama::RecordCoord rc = {}) const -> llama::NrAndOffset { // [0][0] is at left top const auto [row, col] = ai; diff --git a/include/llama/Concepts.hpp b/include/llama/Concepts.hpp index 70a8efaf6f..ce7f029e0c 100644 --- a/include/llama/Concepts.hpp +++ b/include/llama/Concepts.hpp @@ -23,7 +23,7 @@ namespace llama { m.blobSize(std::size_t{}) } -> std::same_as; { m.blobNrAndOffset(typename M::ArrayIndex{}) } -> std::same_as; { m.template blobNrAndOffset<0>(typename M::ArrayIndex{}) } -> std::same_as; - { m.blobNrAndOffset(typename M::ArrayIndex{}, llama::RecordCoord<0>{}) } -> std::same_as; + { m.blobNrAndOffset(typename M::ArrayIndex{}, {}, llama::RecordCoord<0>{}) } -> std::same_as; }; // clang-format on diff --git a/include/llama/Core.hpp b/include/llama/Core.hpp index fb41824e60..22cfab0cb7 100644 --- a/include/llama/Core.hpp +++ b/include/llama/Core.hpp @@ -30,6 +30,15 @@ namespace llama template inline constexpr bool isAllowedFieldType = std::is_trivially_destructible_v; + template + inline constexpr bool isAllowedFieldType> = true; + + template + inline constexpr bool isAllowedFieldType = isAllowedFieldType; + + template + inline constexpr bool isAllowedFieldType = isAllowedFieldType; + /// Record dimension tree node which may either be a leaf or refer to a child tree presented as another \ref /// Record. /// \tparam Tag Name of the node.
