            Bug ID: 27584
           Summary: nm riscv: Suppress empty name symbols unless
                    --special-syms?
           Product: binutils
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: i at maskray dot me
  Target Milestone: ---

On ARM, mapping symbols are suppressed by default.

% arm-linux-gnueabi-gcc-nm test.o                                      
00000000 T _start
% arm-linux-gnueabi-gcc-nm --special-syms test.o
00000000 t $a.0
00000008 t $d.1
00000000 T _start

RISC-V needs many empty name symbols for -mrelax. Should such symbols be
suppressed as well?
