From d35d2a6640628be7a91230f5b2465710e4f76de7 Mon Sep 17 00:00:00 2001 From: Richard Earnshaw Date: Sat, 22 Mar 2003 16:22:18 +0000 Subject: * arm-tdep.c (setarmcmdlist, showarmcmdlist): New command lists. (set_arm_command, show_arm_command): New functions. (_initialize_arm_tdep): Add them. (num_disassembly_options): Renamed from num_flavor_options. (valid_disassembly_styles): Renamed from valid_flavors. (disassembly_style): Renamed from disassembly_flavor. (set_disassembly_style_sfunc): Renamed from set_disassembly_flavor_sfunc. (set_disassembly_style): Renamed from set_disassembly_flavor. (arm_othernames): Updated. (_initialize_arm_tdep): Deprecate "set/show disassembly-flavor" command. Add "set/show arm disassembly" commands.
