selftests/bpf: Log arg_track_join for stack arg slots in liveness analysis
Commit 2af4e792773f ("bpf: Extend liveness analysis to track stack argument slots")
added stack arg supports. For selftest
verifier_stack_arg/stack_arg: pruning with different stack arg types
the following are two arg JOIN messages:
arg JOIN insn 9 -> 10 r1: fp0-8 + _ => fp0-8|fp0+0
arg JOIN insn 9 -> 10 r11: fp0-8 + _ => fp0-8|fp0+0
Here the "r11:" label for stack arg slot 0 is misleading since r11
is a special register (BPF_REG_PARAMS). The next patch corrects
this to "sa0:", properly representing the 'stack arg slot 0'.
