The idea of this change is simple: Populate a data structure, namely "disasm_option_and_arg_t" from "include/dis-asm.h", to encompass the disassembly options and their possible arguments. This will make it easier to manage or extend those options by adapting entries in a data structure, "arc_options". There will be lesser need to hard-code the options in the code itself. Moreover, ARC GDB will use this population function, "disassembler_options_arc ()", to enable the "set disassembler-option" for ARC targets. The gdb change will be in a separate patch though. The changes in this patch can be divided into: 1) Introduction of "disassembler_options_arc ()" that will return a "disasm_option_and_arg_t" structure representing the disassembly options and their likely arguments. 2) New data type "arc_options_arg_t" and new data "arc_options". These are the internals for keeping track of options and arguments entries that can easily be extended. 3) To print the options, the "print_arc_disassembler_options ()" has been adjusted to use this dynamically built structure instead of having them hard-coded inside. To see this in effect, one can look into the output of: $ ./binutils/objdump --help ... The following ARC specific disassembler options are... ... include/ChangeLog: * dis-asm.h (disassembler_options_arc): New prototype. opcodes/ChangeLog: * arc-dis.c (arc_option_arg_t): New enumeration. (arc_options): New variable. (disassembler_options_arc): New function. (print_arc_disassembler_options): Reimplement in terms of "disassembler_options_arc".
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
