We missed a "_gp" when changing the GP symbol. To make sure that
doesn't happen again, we now use the same definition everywhere (thanks,
Nick).
include/ChangeLog:
2017-04-03 Palmer Dabbelt <palmer@dabbelt.com>
* elf/riscv.h (RISCV_GP_SYMBOL): New define.
bfd/ChangeLog:
2017-04-03 Palmer Dabbelt <palmer@dabbelt.com>
* elfnn-riscv.c (GP_NAME): Delete.
(riscv_global_pointer_value): Change GP_NAME to RISCV_GP_SYMBOL.
(_bfd_riscv_relax_lui): Likewise.
opcodes/ChangeLog:
2017-04-03 Palmer Dabbelt <palmer@dabbelt.com>
* riscv-dis.c (riscv_disassemble_insn): Change "_gp" to
RISCV_GP_SYMBOL.
