As a result xtensa-linux-gdb behaves as xtensa-elf-gdb and cannot communicate with the linux gdbserver. Fix tdep->num_pseudo_regs calculation and call set_gdbarch_num_regs and set_gdbarch_num_pseudo_regs in xtensa_linux_init_abi. gdb/ 2018-11-16 Max Filippov * xtensa-linux-tdep.c (xtensa_linux_init_abi): Update tdep->num_pseudo_regs.
