[Crash-utility] [PATCH 6/6] LoongArch64: print exception registers only with bt -f
LoongArch64 exception frames include a full pt_regs dump. Printing that
register block in normal bt output makes the backtrace harder to scan and
visually separates the exception frame from the frames that follow it.
Keep normal bt output focused on stack frames and print the exception
register block only for full backtraces. The detailed data remains
available with bt -f, where crash already prints per-frame stack details.
