| 14 | // GCC in LTO mode interoperates poorly with non-standard libraries that | |
| 15 | // provide implementations of compiler intrinsics such as memcpy/memset | |
| 16 | // or the stack protector entry points. | |
| 17 | // | |
| 18 | // By referencing these functions from a non-LTO object that can be passed | |
| 19 | // to the linker via the -plugin-opt=-pass-through=-lxxx options, the | |
| 20 | // intrinsics are included in the link in a way that allows them to be | |
| 21 | // pruned again if no other references to them exist. | |
