Beyond the need to encode any registers involved in data transfer and
the address base register for load/stores, it is necessary to specify
the data register addressing mode and whether the address register is
to be pre/post-indexed, whereby loads may be post-indexed and stores
pre-indexed with write-back.
The use of a single bit to specify both the indexing mode and indexing
value requires a novel function be written to accommodate this for
address operand insertion in assembly and another for extraction in
disassembly, along with the definition of two insn fields for use with
these instructions.
This therefore defines the following functions:
- aarch64_ins_rcpc3_addr_opt_offset
- aarch64_ins_rcpc3_addr_offset
- aarch64_ext_rcpc3_addr_opt_offset
- aarch64_ext_rcpc3_addr_offset
It extends the `do_special_{encoding|decoding}' functions and defines
two rcpc3 instruction fields:
- FLD_opc2
- FLD_rcpc3_size
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.
