+
+ * i386-dis.c: Combine aflag and dflag into sizeflag. Change OP_*
+ functions to void.
+ (OP_DSreg): Rename from OP_DSSI.
+ (OP_ESreg): Rename from OP_ESDI.
+ (Xb, Xv, Yb, Yv): Use index reg code, not b_mode or v_mode.
+ (DSBX): Define.
+ (append_seg): Rename from append_prefix.
+ (ptr_reg): New function.
+ (dis386): Add S suffix to pushf, popf, ret, lret, enter, leave.
+ Add DSBX for xlat.
+ (PREFIX_ADDR): Rename from PREFIX_ADR.
+ (float_reg): Add non-broken opcodes for people who don't want
+ UNIXWARE_COMPAT.
+
Fri Jun 5 19:15:04 1998 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* m68k-opc.c (tstb, tstw, tstl): Don't allow pcrel on
