May 10, 2018 · Address Spaces ¶ The AMDGPU backend uses the following address space mappings. Introduction ¶ The AMDGPU backend provides ISA code generation for AMD GPUs, starting with the R600 family up until the current GCN families. Sep 13, 2025 · The AMDGPU backend provides instruction information and instruction selection for AMD GPU programming within the LLVM compiler infrastructure. - llvm/llvm-project Apr 24, 2025 · The AMDGPU target in LLVM provides a complete compilation pipeline from LLVM IR to native AMD GPU machine code. We add openmp to LLVM_ENABLED_RUNTIMES so it is built for the default target and provides OpenMP support. Overview ¶ An overview of generic syntax and other features of AMDGPU instructions may be found in this document. g. It supports various AMD GPU architectures through a set of subtargets, with specialized handling for different GPU generations. We need clang to build the GPU C library and lld to link AMDGPU executables, so we enable them in LLVM_ENABLE_PROJECTS. This backend transforms LLVM IR into optimized GPU machine code for AMD Graphics Processing Units, focusing on the Southern Islands (SI) family and later GCN (Graphics Core Next) architectures. .

The buffer fat pointer is an experimental address space that is currently unsupported in the We need clang to build the GPU C library and lld to link AMDGPU executables, so we enable them in LLVM_ENABLE_PROJECTS. The LLVM Project is a collection of modular and reusable compiler and toolchain technologies. The memory space names used in the table, aside from the region memory space, is from the OpenCL standard. Find out the rules and conventions for opcode mnemonic, type and size suffices, encoding suffices, operands and modifiers.
