Currently there are many prefix commands that do nothing but call either help_list or cmd_show_list. I happened to notice that one such call, for "set print type", used the wrong command list parameter, causing incorrect output. Rather than fix this bug in isolation, I decided to eliminate this possibility by adding two new ways to add prefix commands, which simply route the call to help_list or cmd_show_list, as appropriate. This makes it impossible for a mismatch to occur. In some cases, a bit of output was removed; however, I don't think this output in general was very useful. It seemed redundant with what's already printed by help_list. A representative example is this hunk, removed from ada-lang.c: - printf_unfiltered (_(\ -"\"set ada\" must be followed by the name of a setting.\n")); This simplified the CLI style set/show commands quite a bit, and allowed the deletion of a macro. This also cleans up some unusual code in windows-tdep.c. Tested on x86-64 Fedora 30. Note that I have no way to build the go32-nat.c change. gdb/ChangeLog 2020-04-17 Tom Tromey <tromey@adacore.com> * auto-load.c (show_auto_load_cmd): Remove.
