* [_stext, _etext]: contains .text.* sections, may also contain .rodata.* |

* [_sdata, _edata]: contains .data.* sections, may also contain .rodata.* |

* and/or .init.* sections. |
|
* [__start_rodata, __end_rodata]: contains .rodata.* sections |
|
* [__init_begin, __init_end]: contains .init.* sections, but .init.text.* |
|
* may be out of this range on some architectures. |
|
* [_sinittext, _einittext]: contains .init.text.* sections |
|
* [__bss_start, __bss_stop]: contains BSS sections |

* Following global variables are optional and may be unavailable on some |
