| 4 | Subject: [PATCH 2/2] Makefile: add target to split profile generation |
| 5 | |
| 6 | We don't want to have profile task invoked from here and want to use |
| 7 | qemu-user instead. Split the profile-opt task so qemu can be invoked |
| 8 | once binaries have been built with instrumentation and then we can go |
| 9 | ahead and build again using the profile data generated. |

| 11 | Upstream-Status: Inappropriate [OE-specific] |
