Re: [gentoo-user] CFLAGs for kernel compilation

[Ralf]

Damn, you're absolutely right.

I just tested it using make V=1.
kernel make does override CFLAGs from the outside.

But that's interesting: my processor supports -march=core-avx2 and none
of the linux kernel processor family uses this flag...

Thx
