Bug ID: 108634
Summary: [13 regression] 'undefined symbol: tree_code_type'
when building kernel GCC plugins since
r13-5431-gb0241ce6e37031
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: plugins
Assignee: unassigned at gcc dot gnu.org
Reporter: sam at gentoo dot org
CC: jakub at gcc dot gnu.org
Target Milestone: ---
When building kernel 6.1.9:
```
cc1: error: cannot load plugin
./scripts/gcc-plugins/randomize_layout_plugin.so:
./scripts/gcc-plugins/randomize_layout_plugin.so: undefined symbol:
tree_code_type

```
This happens since r13-5431-gb0241ce6e37031 which changes the visibility
(thanks to Arsen and pinskia for spotting this) of some of the symbols.
It's unclear to me if this is a kernel or GCC issue though (should the kernel
be using different methods in its plugin?)
