In the operand handling rewrite made for the MIPS disassembler with
commit ab90248154ba ("Add structures to describe MIPS operands"),
<https://sourceware.org/ml/binutils/2013-07/msg00135.html>, the `g'
operand code has become redundant for the regular MIPS instruction set
by duplicating the OP_REG_COPRO semantics of the `G' operand code.
Later commit 351cdf24d223 ("Implement O32 FPXX, FP64 and FP64A ABI
extensions") converted the CTTC1 instruction from the `g' to the `G'
operand code, but still left a few instructions behind.
Convert the three remaining instructions still using the `g' code then,
namely: CTTC2, MTTC2 and MTTHC2, and remove all traces of the operand
code, freeing it up for other use.
opcodes/
* mips-opc.c (mips_builtin_opcodes): Switch "cttc2", "mttc2",
and "mtthc2" to using the `G' rather than `g' operand code for
the coprocessor control register referred.
include/
* opcode/mips.h: Complement change made to opcodes and remove
references to the `g' regular MIPS ISA operand code.
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.
