13 /* Note: we always define __CTOR_LIST__ and ___CTOR_LIST__ here,
14 we do not PROVIDE them. This is because the ctors.o startup
15 code in libgcc defines them as common symbols, with the
16 expectation that they will be overridden by the definitions
17 here. If we PROVIDE the symbols then they will not be
18 overridden and global constructors will not be run.
19 See PR 22762 for more details.

21 This does mean that it is not possible for a user to define
22 their own __CTOR_LIST__ and __DTOR_LIST__ symbols; if they do,
23 the content from those variables are included but the symbols
24 defined here silently take precedence. If they truly need to
25 be redefined, a custom linker script will have to be used.
26 (The custom script can just be a copy of this script with the
27 PROVIDE() qualifiers added).
28 In particular this means that ld -Ur does not work, because
29 the proper __CTOR_LIST__ set by ld -Ur is overridden by a
30 bogus __CTOR_LIST__ set by the final link. See PR 46. */
