Nope. Just three instructions that got re-ordered from ABC to CAB in a
way that makes no difference. But just the knowledge that "-g" affects
code generation is nasty. And with "allmodconfig" my build fails
almost immediately (failures on at least arch/x86/kernel/process_64.c,
kernel/exit.c and mm/vmalloc.c in that case. I was too lazy to check
what the differences were).

Does anybody have current gcc build and can verify that current gcc
tip passes the kernel compile with that

export GCC_COMPARE_DEBUG=1

thing?
