you're right, I compiled tar and hello program with -march=bdver2 option without problem so gcc-8 is sure. I saw that all warnings that they appear during kernel compilation process concern "objtool" mm/memory.o: warning: objtool: remap_pfn_range()+0xd5: unsupported intra-function call that it's part of linux-kbuild-4.19 package maybe I should submit a bug report to this package or is another one a better choice?
