# mem_alloc_bench — 跨平台构建
#
#   make            本机 (macOS/Linux) 编译 mem_stress + mem_bench
#   make ios        交叉编译 iOS arm64 二进制 (输出到 ios/)
#   make ohos       交叉编译 HarmonyOS arm64 二进制 (输出到 ohos/, 需 OHOS NDK)
#   make clean
#
# OHOS NDK 路径按实际安装位置覆盖, 例如:
#   make ohos OHOS_NATIVE=/path/to/openharmony/native
