Also fix the incorrect definitions of multiply and divide carry and overflow float. Changes to the instructions are made in the .cpu file, then we regenerate the binutils and sim files. The changes also required a few fixups for tests and additional sim helpers. cpu/ChangeLog: yyyy-mm-dd Richard Henderson <rth@twiddle.net> Stafford Horne <shorne@gmail.com> * or1korbis.cpu (insn-opcode-mac): Add opcodes for MACU and MSBU. (insn-opcode-alu-regreg): Add opcodes for MULD and MULDU. (l-mul): Fix overflow support and indentation. (l-mulu): Fix overflow support and indentation. (l-muld, l-muldu, l-msbu, l-macu): New instructions. (l-div); Remove incorrect carry behavior. (l-divu): Fix carry and overflow behavior. (l-mac): Add overflow support. (l-msb, l-msbu): Add carry and overflow support. opcodes/ChangeLog: yyyy-mm-dd Richard Henderson <rth@twiddle.net> Stafford Horne <shorne@gmail.com> * or1k-desc.c: Regenerate. * or1k-desc.h: Regenerate. * or1k-opc.c: Regenerate. * or1k-opc.h: Regenerate. * or1k-opinst.c: Regenerate. sim/common/ChangeLog: yyyy-mm-dd Stafford Horne <shorne@gmail.com> * cgen-ops.h (ADDCFDI): New function, add carry flag DI variant. (ADDOFDI): New function, add overflow flag DI variant. (SUBCFDI): New function, subtract carry flag DI variant. (SUBOFDI): New function, subtract overflow flag DI variant. sim/ChangeLog: yyyy-mm-dd Stafford Horne <shorne@gmail.com> * or1k/cpu.h: Regenerate. * or1k/decode.c: Regenerate. * or1k/decode.h: Regenerate. * or1k/model.c: Regenerate. * or1k/sem-switch.c: Regenerate. * or1k/sem.c: Regenerate: sim/testsuite/sim/or1k/ChangeLog: yyyy-mm-dd Stafford Horne <shorne@gmail.com> * div.S: Fix tests to match correct overflow/carry semantics. * mul.S: Likewise. gas/ChangeLog: yyyy-mm-dd Stafford Horne <shorne@gmail.com> * testsuite/gas/or1k/allinsn.s: Add instruction tests for l.muld, l.muldu, l.macu, l.msb, l.msbu. * testsuite/gas/or1k/allinsn.d: Add test results for new instructions. |

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.
