1d37bd83 - perf loongarch: Remove dwarf-regs.c

Fri, 08 Nov 2024 23:45:56 +0000

perf loongarch: Remove dwarf-regs.cThe file just provides the function get_arch_regstr, however, if inthe only caller get_dwarf_regstr EM_HOST is used for the EM_NONE casethe function can never be called. So remove as dead code. Tidy up theEM_NONE cases for loongarch in dwarf-regs.c.Reviewed-by: Masami Hiramatsu (Google) Signed-off-by: Ian Rogers Cc: Anup Patel Cc: Yang Jihong Cc: Palmer Dabbelt Cc: David S.
