        * hppa.h: Delete remaining OLD_TABLE code.  Bring some
        of the comments up-to-date.

        * hppa.h: Update "free list" of letters and update

Thu May 27 19:21:22 1993  Bruce Bauman  ([email protected])

        * 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  ([email protected])

        * 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  ([email protected])

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

Fri May 14 15:15:50 1993  Ian Lance Taylor  ([email protected])

        ("c[0123]"): Define general coprocessor instructions.

Mon May 10 06:02:25 1993  Ken Raeburn  ([email protected])

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

Fri Apr  9 13:26:16 1993  Jim Kingdon  ([email protected])

        * rs6k.h: Clean up instructions for primary opcode 19 (many were

Thu Mar 18 13:45:31 1993  Per Bothner  ([email protected])

        * i386.h:  486 extensions from John Hassey ([email protected]).
        * mips.h:  Add casts, to suppress warnings about shifting too much.

Thu Feb 18 02:03:14 1993  John Gilmore  ([email protected])

        * 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  ([email protected])

        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  ([email protected])

        * vax.h (bb*): Use "v" (bitfield type), not "a" (address operand)
        for operand 2; from John Carr, [email protected].

Wed Nov  4 07:36:49 1992  Ken Raeburn  ([email protected])

        * 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  ([email protected])

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

Tue Sep 22 14:08:14 1992  Ken Raeburn  ([email protected])

        * m68k.h: Added CPU32 support.

Tue Sep 22 00:38:41 1992  John Gilmore  ([email protected])

Thu Sep  3 09:33:22 1992  Steve Chamberlain  ([email protected])

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

Tue Aug 25 23:25:19 1992  Ken Raeburn  ([email protected])

        * 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  ([email protected])

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

Wed Aug 19 11:22:24 1992  Ian Lance Taylor  ([email protected])

        * 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  ([email protected])

        * m68k.h:  Merged in patches (mostly m68040-specific) from
        Colin Smith <[email protected]>.

        * 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  ([email protected])

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

        * 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 Jun 11 12:15:25 1992  John Gilmore  (gnu at cygnus.com)

        * mips.h:  Fix decoding of coprocessor instructions, somewhat.
        (Fix by Eric Anderson, [email protected].)

Thu May 28 11:17:44 1992  Jim Wilson  ([email protected])

        * sparc.h: Add new architecture variant sparclite; add its scan
        and divscc opcodes.  Define ARCHITECTURES_CONFLICT_P macro.

Tue May  5 14:23:27 1992  Per Bothner  ([email protected])

        * mips.h:  Add some more opcode synonyms (from Frank Yellin,
        [email protected]).

        and `fd'.  (From [email protected] (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  ([email protected])

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

Sun Mar 29 12:22:08 1992  John Gilmore  (gnu at cygnus.com)

        * 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  ([email protected])

        * i386.h: added inb, inw, outb, outw opcodes, added att syntax for
          scmp, slod, smov, ssca, ssto.  Curtesy Minh Tran-Le
          <[email protected]>.

        similar instructions -- they've been renamed to "fitoq", etc.
        REALLY fix tsubcctv.  Fix "fcmpeq" and "fcmpq" which had wrong
        number of arguments.
        * h8300.h:  Remove extra ; which produces compiler warning.

        * 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.
