freebsd kernel with SKQ
Go to file
Edward Tomasz Napierala 39e75a5a79 Build debug kernels with -O2.
LLVM 11 changed the meaning of '-O' from '-O2' to '-O1', which resulted
in debug kernels (with 'makeoptions DEBUG=-g') being built with inlining
disabled, causing severe performance hit.

The -O2 was already being used for building amd64, powerpc, and powerpcspe.
