+# 关于dhrystone在IDE上跑分和NSDK命令行跑分不一致的问题
+
+## 问题说明
+
+在0.5.0版本的sdk-nuclei_sdk中，为了IDE上使用libncrt库的时候编译有些程序不报错，设置了会默认带上-msave-restore。但在使用newlib时，该选项会导致跑分降低。
+
+
+
+## 解决方案
+
+在跑分的时候，需要在对应项目的Properties -> C/C++ Build -> Settings中，取消对Small prologue/epilogue(-msave-restore)的选中。
+具体流程和示例图如下：
+
+1. 下载sdk-nuclei_sdk 0.5.0组件包。
+
+2. 新建一个Nuclei RISCV-V C/C++ project。
+
+3. 在新建项目的过程中，选中Dhrystone Benchmark和N307FD Core组件,其他选项默认设置即可。此时运行，跑分为1.405。
+
+4. 但实际在需要跑分时，要先取消选中-msave-restore选项，该跑分结果为1.664。
