The extended instructions implemented in powerpc_macros aren't used by the disassembler. That means instructions like "sldi r3,r3,2" appear in disassembly as "rldicr r3,r3,2,61", which is annoying since many other extended instructions are shown. Note that some of the instructions moved out of the macro table to the opcode table won't appear in disassembly, because they are aliases rather than a subset of the underlying raw instruction. If enabled, rotrdi, extrdi, extldi, clrlsldi, and insrdi would replace all occurrences of rotldi, rldicl, rldicr, rldic and rldimi. (Or many occurrences in the case of clrlsldi if n <= b was added to the extract functions.) The patch also fixes a small bug in opcode sanity checking. include/ * opcode/ppc.h (PPC_OPSHIFT_SH6): Define. opcodes/ * ppc-opc.c (insert_erdn, extract_erdn, insert_eldn, extract_eldn), (insert_crdn, extract_crdn, insert_rrdn, extract_rrdn), (insert_sldn, extract_sldn, insert_srdn, extract_srdn), (insert_erdb, extract_erdb, insert_csldn, extract_csldb), (insert_irdb, extract_irdn): New functions.

(powerpc_opcodes): Add "rotrdi", "srdi", "extrdi", "clrrdi", "sldi", "extldi", "clrlsldi", "insrdi" and corresponding record (ie. dot suffix) forms.

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.
