  "message": "[gdb/tdep, aarch64] Remove fp and sp reg aliases, add x31 reg alias\n\nIn aarch64-tdep.c we find these register aliases:\n...\n{\n  /* 64-bit register names.  */\n  {\"fp\", AARCH64_FP_REGNUM},\n  {\"lr\", AARCH64_LR_REGNUM},\n  {\"sp\", AARCH64_SP_REGNUM},\n...\n\nThe sp alias is superfluous, because the canonical name of x31 is already sp.\n\nThe fp alias is superfluous, because it\u0027s already taken by the default meaning\nof fp, assigned here in _initialize_frame_reg:\n...\n  user_reg_add_builtin (\"fp\", value_of_builtin_frame_fp_reg, NULL);\n...\n\nFix this by removing the fp and sp aliases.\n\nWhile we\u0027re at it, add an x31 alias for sp.\n\nApproved-By: Luis Machado \u003cluis.machado@arm.com\u003e\n\nTested on aarch64-linux.\nPR tdep/30012\nBug: https://sourceware.org/bugzilla/show_bug.cgi?id\u003d30012\n",
