I don't know, to me it sounds more like little bugs on kernel
side, patches silencing
I was thinking to submit a bug report against gcc-8 package. Now that I
have a work around, "bdver1" compiles without warnings, I can say
enough, what do you think about?

Hi, everybody
in order to achieve Linux kernel optimized for my CPU AMD FX-8350
Bulldozer2 I changed the line 121 of linux-source-4.19/arch/x86/Makefile
from:
cflags-$(CONFIG_MK8) += $(call cc-option,-march=k8)
to:
cflags-$(CONFIG_MK8) += $(call cc-option,-march=bdver2) \
10 matches
