# 作用：统计在zCore上通过的系统调用和libc-test测例
|
||
# 使用方法：
|
||
# ./statistic -e <dir> : 提取每个测例所依赖的系统调用，包含系统调用的文件和测例同名，放在$SYSCALL_DIR目录
|
||
# <dir> : 测例所在的目录，一般来说这个目录的名字就是libc-test
|
||
# ./statistic -a <arch> : 把已通过的测例所包含的系统调用合并到一个文件，前提是要求$SYSCALL_DIR目录存在
|
||
# <arch> : 测例的架构，比如x86_64、riscv64等
|
||
# ./statistic -a <arch> -e <dir> : 先从测例提取系统调用，再合并所需的系统调用，就是上面的两步合而为一
