| 4 | Subject: [PATCH] runtime/cgo: add -fno-stack-protector to CFLAGS |
| 5 | |
| 6 | Some compilers default to having -fstack-protector on, which breaks |
| 7 | when using internal linking because the linker doesn't know how to |
| 8 | find the support functions. |
| 9 | |
| 10 | Fixes #52919 |
| 11 | Fixes #54313 |
| 12 | |
| 13 | Change-Id: I6f51d5e906503f61fc768ad8e30c163bad135087 |
