        * Patches from Jeffrey Law <law@cs.utah.edu>.
        * hppa.h: Rework single precision FP
        instructions so that they correctly disassemble code
        PA1.1 code.

Thu May 27 19:21:22 1993  Bruce Bauman  (boot@osf.org)

        * i386.h (i386_optab, mov pattern): Remove Mem16 restriction from
        mov to allow instructions like mov ss,xyz(ecx) to assemble.

Tue May 25 00:39:40 1993  Ken Raeburn  (raeburn@cygnus.com)

        * hppa.h: Use new version from Utah if OLD_TABLE isn't defined;
        gdb will define it for now.

Mon May 24 15:20:06 1993  Ken Raeburn  (raeburn@cambridge.cygnus.com)

        * sparc.h: Don't end enumerator list with comma.

Fri May 14 15:15:50 1993  Ian Lance Taylor  (ian@cygnus.com)

        * Based on patches from davidj@ICSI.Berkeley.EDU (David Johnson):
        * mips.h (OP_MASK_COPZ, OP_SH_COPZ): Define.
        ("bc2t"): Correct typo.
        ("[ls]wc[023]"): Use T rather than t.
        ("c[0123]"): Define general coprocessor instructions.

Mon May 10 06:02:25 1993  Ken Raeburn  (raeburn@kr-pc.cygnus.com)

        * m68k.h: Move split point for gcc compilation more towards
        middle.

Fri Apr  9 13:26:16 1993  Jim Kingdon  (kingdon@cygnus.com)

        * rs6k.h: Clean up instructions for primary opcode 19 (many were
        simply wrong, ics, rfi, & rfsvc were missing).
        Add "a" to opr_ext for "bb".  Doc fix.

Thu Mar 18 13:45:31 1993  Per Bothner  (bothner@rtl.cygnus.com)

        * i386.h:  486 extensions from John Hassey (hassey@dg-rtp.dg.com).
        * mips.h:  Add casts, to suppress warnings about shifting too much.
        * m68k.h:  Document the placement code '9'.

Thu Feb 18 02:03:14 1993  John Gilmore  (gnu@cygnus.com)

        * m68k.h (BREAK_UP_BIG_DECL, AND_OTHER_PART):  Add kludge which
        allows callers to break up the large initialized struct full of
        opcodes into two half-sized ones.  This permits GCC to compile
        this module, since it takes exponential space for initializers.
        (numopcodes, endop):  Revise to use AND_OTHER_PART in size calcs.

Thu Feb  4 02:06:56 1993  John Gilmore  (gnu@cygnus.com)

        * a29k.h:  Remove RCS crud, update GPL to v2, update copyrights.

        Delta 88 changes inspired by Carl Greco, <cgreco@Creighton.Edu>:
        * m88k.h (PMEM):  Avoid previous definition from <sys/param.h>.
        (AND):  Change to AND_ to avoid ansidecl.h `AND' conflict.

Sat Jan 23 18:10:49 PST 1993  Ralph Campbell  (ralphc@pyramid.com)

        * mips.h: document "i" and "j" operands correctly.

Thu Jan  7 15:58:13 1993  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

        * mips.h: Removed endianness dependency.

        and deposit instructions.

Sat Dec 12 16:09:48 1992  Ian Lance Taylor  (ian@cygnus.com)

        * i386.h: accept shld and shrd both with and without the shift
        count argument, which is always %cl.

Fri Nov 27 17:13:18 1992  Ken Raeburn  (raeburn at cygnus.com)

        * i386.h (i386_optab_end, i386_regtab_end): Now const.
        (one_byte_segment_defaults, two_byte_segment_defaults,
        i386_prefixtab_end): Ditto.

Mon Nov 23 10:47:25 1992  Ken Raeburn  (raeburn@cygnus.com)

        * vax.h (bb*): Use "v" (bitfield type), not "a" (address operand)
        for operand 2; from John Carr, jfc@dsg.dec.com.

Wed Nov  4 07:36:49 1992  Ken Raeburn  (raeburn@cygnus.com)

        * m68k.h: Define FIXED_SIZE_BRANCH, so bsr and bra instructions
        always use 16-bit offsets.  Makes calculated-size jump tables
        feasible.

Fri Oct 16 22:52:43 1992  Ken Raeburn  (raeburn@cygnus.com)

        * i386.h: Fix one-operand forms of in* and out* patterns.

        * m68k.h: merged Motorola and MIT syntax.

Thu Sep  3 09:33:22 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

        * m68k.h (pmove): make the tests less strict, the 68k book is
        wrong.

Tue Aug 25 23:25:19 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)

        * m68k.h (m68ec030): Defined as alias for 68030.
        (m68k_opcodes): New type characters "3" for 68030 MMU regs and "t"
        for immediate 0-7 added.  Set up some opcodes (ptest, bkpt) to use
        them.  Tightened description of "fmovex" to distinguish it from
        some "pmove" encodings.  Added "pmove" for 68030 MMU regs, cleaned
        up descriptions that claimed versions were available for chips not
        supporting them.  Added "pmovefd".

Mon Aug 24 12:04:51 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

        * m68k.h: fix where the . goes in divull

Wed Aug 19 11:22:24 1992  Ian Lance Taylor  (ian@cygnus.com)

        * m68k.h: the cas2 instruction is supposed to be written with
        indirection on the last two operands, which can be either data or
        address registers.  Added a new operand type 'r' which accepts
        either register type.  Added new cases for cas2l and cas2w which
        use them.  Corrected masks for cas2 which failed to recognize use
        of address register.

Fri Aug 14 14:20:38 1992  Per Bothner  (bothner@cygnus.com)

        * m68k.h:  Merged in patches (mostly m68040-specific) from
        Colin Smith <colin@wrs.com>.

        * m68k.h:  Merged m68kmri.h and m68k.h (using the former as a
        base).  Also cleaned up duplicates, re-ordered instructions for
        the sake of dis-assembling (so aliases come after standard names).
        * m68kmri.h: Now just defines some macros, and #includes m68k.h.

Wed Aug 12 16:38:15 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

        * m68kmri.h: added various opcodes. Moved jbxx to bxxes. Filled in
        all missing .s

        so that the Lucid C compiler can digest this as well...

Fri Jun 26 21:27:17 1992  John Gilmore  (gnu at cygnus.com)

        * i386.h:  Add setc, setnc, addr16, data16, repz, repnz aliases.
        Fix opcodes on various sizes of fild/fist instructions
        (16bit=no suffix, 32bit="l" suffix, 64bit="ll" suffix).
        Use tabs to indent for comments.  Fixes suggested by Minh Tran-Le.

Thu Jun 25 16:13:26 1992  Stu Grossman  (grossman at cygnus.com)

        * h8300.h:  Fill in all the holes in the opcode table so that the
        losing HPUX C compiler can digest this...

Thu Apr  9 00:31:19 1992  Per Bothner  (bothner@rtl.cygnus.com)

        * rs6k.h: Fix incorrect extended opcode for instructions `fm'
        and `fd'.  (From metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik).)

Tue Apr  7 13:38:47 1992  Stu Grossman  (grossman at cygnus.com)

        * rs6k.h:  Move from ../../gdb/rs6k-opcode.h.

Fri Apr  3 11:30:20 1992  Fred Fish  (fnf@cygnus.com)

        * m68k.h (one, two):  Cast macro args to unsigned to suppress
        complaints from compiler and lint about integer overflow during
        shift.

        * sparc.h (OP):  Avoid signed overflow when shifting to high order bit.

Fri Mar  6 00:22:38 1992  John Gilmore  (gnu at cygnus.com)

        * mips.h:  Make bitfield layout depend on the HOST compiler,
        not on the TARGET system.

Fri Feb 21 01:29:51 1992  K. Richard Pixley  (rich@cygnus.com)

        * i386.h: added inb, inw, outb, outw opcodes, added att syntax for

Fri Dec 27 10:55:50 1991  Per Bothner  (bothner at cygnus.com)

        * sparc.h (nop):  Made the 'lose' field be even tighter,
        so only a standard 'nop' is disassembled as a nop.

Sun Dec 22 12:18:18 1991  Michael Tiemann  (tiemann at cygnus.com)

        * sparc.h (nop): Add RD_GO to `lose' so that only %g0 in dest is
        disassembled as a nop.

Tue Dec 10 00:22:20 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
