Expand "show disassembler-options" output
I typed this: (gdb) help set disassembler-options Set the disassembler options. Usage: set disassembler-options OPTION [,OPTION]... See: 'show disassembler-options' for valid option values. ... so I tried what it said and got: (gdb) show disassembler-options The current disassembler options are '' This surprised me a little, so this patch adds some text to explain the situation when an architecture does not have disassembler options. While there I noticed one more spot where gdb was not using the GNU style for metasyntactic variables. This patch fixes this as well. gdb/ChangeLog 2018-09-16 Tom Tromey <tom@tromey.com> * disasm.c (show_disassembler_options_sfunc): Use GNU style for metasyntactic variables. Print message if no disassembler options are available.
