/* 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. |
| 20 |
|
| 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. */ |
