glibc 库, 不仅可以学习使用库函数,还可以学习函数的具体实现,是提高功力的好资料

libc {
  GLIBC_2.1.1 {
    # SPARC v9 SYSV ABI helper functions
    __align_cpy_1; __align_cpy_2; __align_cpy_4;
    __align_cpy_8; __align_cpy_16;
  }
}
libm {
  GLIBC_2.1 {
    # A generic bug got this omitted from other configurations' version
    # sets, but we always had it.
    exp2l;
  }
}
