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