amdgcn-amdhsa	[libclc] Remove catch-all opencl/clc.h (#147490) This commit finishes the work started in #146840 and #147276. It makes each OpenCL header self-contained and each implementation file include only the headers it needs. It removes the need for a catch-all include file of all OpenCL builtin declarations.	1 年前
amdgcn	[libclc] Use CLC atomic functions for legacy OpenCL atom/atomic builtins (#168325) Main changes: * OpenCL legacy atom/atomic builtins now call CLC atomic functions (which use Clang __scoped_atomic_*), replacing previous Clang __sync_* functions. * Change memory order from seq_cst to relaxed; keep device scope (spec permits broader than workgroup). LLVM IR for _Z8atom_decPU3AS1Vi in amdgcn--amdhsa.bc: Before: %2 = atomicrmw volatile sub ptr subrspace(1) %0, i32 1 syncscope("agent") seq_cst After: %2 = atomicrmw volatile sub ptr subrspace(1) %0, i32 1 syncscope("agent") monotonic * Also adds OpenCL 1.0 atom_* variants without volatile on the pointer. They are added for backward compatibility.	8 个月前
clspv	[NFC][libclc] add missing __CLC_ prefix all internal macros (#153523) This unifies naming scheme of macros to address review comment https://github.com/intel/llvm/pull/19779#discussion_r2272194357 math constant value macros are not changed, e.g. #define AU0 -9.86494292470009928597e-03	11 个月前

ptx-nvidiacl	[libclc] update __clc_mem_fence: add MemorySemantic arg and use __builtin_amdgcn_fence for AMDGPU (#152275) It is necessary to add MemorySemantic argument for AMDGPU which means the memory or address space to which the memory ordering is applied. The MemorySemantic is also necessary for implementing the SPIR-V MemoryBarrier instruction. Additionally, the implementation of __clc_mem_fence on Intel GPUs requires the MemorySemantic argument. Using __builtin_amdgcn_fence for AMDGPU is follow-up of https://github.com/llvm/llvm-project/pull/151446#discussion_r2254006508 llvm-diff shows no change to nvptx64--nvidiacl.bc.	11 个月前
