Add disassembler helper for GDB, that uses opcodes structure arc_instruction and adds convenience functions to handle instruction operands. This interface solves at least those problems with arc_instruction: * Some instructions, like "push_s", have implicit operands which are not directly present in arc_instruction. * Operands of particular meaning, like branch/jump targets, have various locations and meaning depending on type of branch/target. * Access to operand value is abstracted into a separate function, so callee code shouldn't bother if operand value is an immediate value or in a register. Testcases included in this commit are fairly limited - they test exclusively branch instructions, something that will be used in software single stepping. Most of the other parts of this disassembler helper are tested during prologue analysis testing. gdb/ChangeLog: yyyy-mm-dd Anton Kolesov <anton.kolesov@synopsys.com> * configure.tgt: Add arc-insn.o. * arc-tdep.c (arc_delayed_print_insn): Make non-static.

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.
