[PATCH] OpenRISC support for opcodes

To: binutils at sources dot redhat dot com
Subject: [PATCH] OpenRISC support for opcodes
From: Johan Rydberg <johan dot rydberg at netinsight dot se>

Hi!

Here's a patch that add support for OpenRISC to opcodes.  The openrisc-*
files need to be generated from src/cgen/openrisc.cpu.

I will post a patch for "ld" and "gas" within some days, it just needs some
more work before it can be contributed.


/src/include:
2001-04-24  Johan Rydberg  <jrydberg@opencores.org>

        * dis-asm.h (print_insn_openrisc): Add prototype.

/src/opcodes:
2001-04-24  Johan Rydberg  <jrydberg@opencores.org>

        * Makefile.am: Add OpenRISC target.
        * Makefile.in: Regenerated.

        * disassemble.c (disassembler): Recognize the OpenRISC disassembly.

        * configure.in (bfd_openrisc_arch): Add target.
        * configure: Regenerated.

        * openrisc-asm.c: New file.
        * openrisc-desc.c: Likewise.
        * openrisc-desc.h: Likewise.
        * openrisc-dis.c: Likewise.
        * openrisc-ibld.c: Likewise.
        * openrisc-opc.c: Likewise.
        * openrisc-opc.h: Likewise.

/src/binutils:
2001-04-24  Johan Rydberg  <jrydberg@opencores.org>

        * NEWS: Announce support for OpenRISC.

+* Support for OpenRISC by Johan Rydberg.
+
 * New command line switch to objcopy -B (or --binary-architecture) which sets
   the archiceture of the output file to the given argument.  This option only
   makes sense, if the input target is binary.  Otherwise it is ignored.
