FYI, this is from 4.14.15's ChangeLog, doesn't appear to be in 4.9.78 |
| 22 |
though. |

objtool: Fix seg fault with gold linker |
| 29 |
|
| 30 |
commit 2a0098d70640dda192a79966c14d449e7a34d675 upstream. |
| 31 |
|
| 32 |
Objtool segfaults when the gold linker is used with |
| 33 |
CONFIG_MODVERSIONS=y and CONFIG_UNWINDER_ORC=y. |
| 34 |
|
| 35 |
With CONFIG_MODVERSIONS=y, the .o file gets passed to the linker before |
| 36 |
being passed to objtool. The gold linker seems to strip unused ELF |
| 37 |
symbols by default, which confuses objtool and causes the seg fault when |
| 38 |
it's trying to generate ORC metadata. |
| 39 |
|
| 40 |
Objtool should really be running immediately after GCC anyway, without a |
| 41 |
linker call in between. Change the makefile ordering so that objtool is |
| 42 |
called before the linker. |
