Fix for remote G Packet message too long error for baremetal. Prior to version MicroBlaze v8.10.a,EDK 13.1, XMD's gdbserver stub returned 57 registers in response to GDB's G request. Starting with version MicroBlaze v8.10.a, EDK 13.1, XMD added the slr and shr register, for a count of 59 registers. This patch adds these registers to the expected G response. This patch fixes the above problem for baremetal and also supports the backward compatibility. ChangeLog: 2014-07-02 Ajit Agarwal <ajitkum@xilinx.com> * microblaze-tdep.c (microblaze_register_names): Add the rshr and rslr register names. (microblaze_gdbarch_init): Use of tdesc_has_registers. Use of tdesc_find_feature. Use of tdesc_data_alloc. Use of tdesc_numbered_register. Use of microblaze_register_g_packet_guesses. Use of tdesc_use_registers. Use of set_gdbarch_register_type. (microblaze_register_g_packet_guesses): New. * microblaze-tdep.h (microblaze_reg_num): Add field MICROBLAZE_SLR_REGNUM MICROBLAZE_SHR_REGNUM MICROBLAZE_NUM_REGS and MICROBLAZE_NUM_CORE_REGS. (microblaze_frame_cache): Use of MICROBLAZE_NUM_REGS. * features/microblaze-core.xml: New file. * features/microblaze-stack-protect.xml: New file. * features/microblaze-with-stack-protect.c: New file. * features/microblaze-with-stack-protect.xml: New file. * features/microblaze.xml: New file. * features/microblaze.c: New file. * features/Makefile (microblaze-with-stack-protect): Add microblaze-with-stack-protect microblaze and microblaze-expedite. * regformats/microblaze-with-stack-protect.dat: New file. * regformats/microblaze.dat: New file. * doc/gdb.texinfo (MicroBlaze Features): New.
