            Bug ID: 23825
           Summary: Linker creates COPY relocs for reference to TLS
                    symbols
           Product: binutils
           Version: 2.31
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: address@hidden

  Target Milestone: ---
            Target: riscv64-*-*

When linking elf/tst-tls12 from glibc the linker creates COPY relocs for the
references to the TLS symbols a1 and a2, ending up overwriting the
.preinit_array and .init_array contents.

$ objdump -t tst-tls12.o | grep 'a[12]'
0000000000000000         *UND*  0000000000000000 a1
0000000000000000         *UND*  0000000000000000 a2
$ objdump -R tst-tls12 | grep COPY
0000000000013d68 R_RISCV_COPY      a1
0000000000013d78 R_RISCV_COPY      a2
$ objdump -p tst-tls12 | grep INIT
  PREINIT_ARRAY        0x0000000000013d68
  PREINIT_ARRAYSZ      0x0000000000000008
  INIT_ARRAY           0x0000000000013d70
  INIT_ARRAYSZ         0x0000000000000008
