From f3ba8a01e66b1f0ec124a68f876a6f56c347bcd1 Mon Sep 17 00:00:00 2001 From: zuco <1808348@qq.com> Date: Mon, 3 Aug 2026 14:59:14 +0800 Subject: [PATCH 1/6] feat: Adapt to aarch64 platform Directory restructuring: - Move source files to lib/ and examples/ subdirectories - Add separate CMakeLists.txt for lib/ and examples/ aarch64 platform adaptation: - Add aarch64 context switch assembly (coctx_swap.S) - Add aarch64 coctx_make implementation - Add get_sp() helper for stack pointer on aarch64 - Add co_free_sharestack() and co_destruct_curr_thread_env() APIs - Fix memory leaks (set pointers to nullptr after free) - Add shared stack parameter validation --- .gitignore | 3 + CMakeLists.txt | 55 ++++----------- examples/CMakeLists.txt | 19 ++++++ .../example_closure.cpp | 0

vectorized memcpy with save/swap temporal hints - Split co_memcpy into co_memcpy_save (ldp+stnp) and co_memcpy_swap (ldnp+stp) - save: write-not-immediately-read, non-temporal store avoids cache pollution - swap: write-immediately-read, non-temporal load + temporal store for cache locality - <=1KB uses memcpy_blk (128B blocks), >1KB uses 384B block loop - Parameterized NEON macros: memcpy_blk_neon and memcpy_384B_neon with ld/st hints - 64-byte dst alignment pre-processing preserved --- lib/CMakeLists.txt | 1 + lib/co_memcpy.c | 95 ++++++++++++++++++++++++++++++++++++++++++

3/6] feat: 512B block + remainder NEON inline + instruction reschedule OP-1: Inline 32B NEON remainder handling in 384B/512B macros, eliminating memcpy_rem call overhead for common remainder sizes (32/64/96B). Fixes 4K+64B ~3% regression. OP-2: Instruction reschedule in 512B loop - load-store spacing increased to >=3 instructions to hide ARM load latency (3-4 cycles on Cortex-A72/A76). OP-3: New 512B (4x128B) block path for >4KB data, reducing loop overhead by 25% vs 384B. Register reuse (q0-q7 recycled after G1 stores complete). OP-4: Remainder handling inherits save/swap temporal strategy (ldp+stnp for save, ldnp+stp for swap) automatically, extending cache pollution control to remainder bytes. --- lib/co_memcpy.c | 39 ++++++++++++++------ lib/memcpy_def.h | 7 +++- lib/memcpy_neon_impl.h | 84 +++++++++++++++++++++++++++++++++++++++++- 3 files changed, 114 insertions(+), 16 deletions(-) diff --git a/lib/co_memcpy.c b/lib/co_memcpy.c index 26f1454..212e6ef 100644 --- a/lib/co_memcpy.c +++ b/lib/co_memcpy.c @@ -5,6 +5,7 @@ #define SIZE_128B 128 #define SIZE_1KB 1024 +#define SIZE_4KB 4096 static void *co_memcpy_save_aarch64(void *restrict dst, const void *restrict src, unsigned long len) { @@ -24,15 +25,22 @@ static void *co_memcpy_save_aarch64(void *restrict dst, const void *restrict src } int len_count = len / BLOCK_SIZE;

charset=UTF-8 Content-Transfer-Encoding: 8bit OP-8: New 256B (2x128B) block path for 1K-2K data.
