1 Linker Script implementation notes and policy
5 implementation policy is to implement linker script features as they are
7 We consider it a bug if the lld implementation does not agree with the manual
11 an implementation. In particular some features are only defined by the
12 implementation and have changed over time.
14 The lld implementation policy for properties of linker scripts that are not
15 defined by the documentation is to follow the GNU ld implementation wherever
16 possible. We reserve the right to make different implementation choices where
30 The first form defines ``symbol``. If ``symbol`` is already defined, it will be
31 overridden. The other form requires ``symbol`` to be already defined.

61 command is followed by ``INSERT``, LLD applies built-in rules which are similar
64 - Align the first section in a ``PT_LOAD`` segment according to
65 ``-z noseparate-code``, ``-z separate-code``, or
66 ``-z separate-loadable-segments``
67 - Define ``__bss_start``, ``end``, ``_end``, ``etext``, ``_etext``, ``edata``,
69 - Sort ``.ctors.*``/``.dtors.*``/``.init_array.*``/``.fini_array.*`` and
71 - Place input ``.text.*`` into output ``.text``, and handle certain variants
