Re: [PATCH v4 6/6] Add Propeller configuration for kernel build.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



While Propeller often works best with AutoFDO (or the instrumentation
based FDO), it's not required. One can use Propeller (or similar
post-link-optimizer, like Bolt) on plain kernel builds.

So I will remove "depends on AUTOFDO_CLANG". I will not use "imply" --
simpler is better here.
