+Thu Jul 1 20:36:17 1993 Doug Evans (dje@canuck.cygnus.com)
+
+ * h8300.h: Fix typo in UNOP3 (affected sh[al][lr].l).
+
+Fri Jun 11 18:38:44 1993 Ken Raeburn (raeburn@cygnus.com)
+
+ Patches from Jeff Law, law@cs.utah.edu:
+ * hppa.h: Clean up some of the OLD_TABLE, non-OLD_TABLE braindamage.
+ Make the tables be the same for the following instructions:
+ "bb", "addb[tf]", "addib[tf]", "add", "add[loc]", "addco",
+ "sh[123]add", "sh[123]add[lo]", "sub", "sub[obt]", "sub[bt]o",

+ "frnd", "fcpy", "fcnvff", "fcnvxf", "fcnvfx", "fcnvfxt",
+ "fcmp", and "ftest".
+
+ * hppa.h: Make new and old tables the same for "break", "mtctl",
+ "mfctl", "bb", "ssm", "rsm", "xmpyu", "fmpyadd", "fmpysub".
+ Fix typo in last patch. Collapse several #ifdefs into a
+ single #ifdef.
+
+ * hppa.h: Delete remaining OLD_TABLE code. Bring some
+ of the comments up-to-date.
+
+ * hppa.h: Update "free list" of letters and update
+ comments describing each letter's function.

+/* These are bit masks and shift counts to use to access the various

+ i = (i &~ (OP_MASK_X << OP_SH_X)) | (j << OP_SH_X)
+
+ Make sure you use fields that are appropriate for the instruction,
+ of course.
+
+ The 'i' format uses OP, RS, RT and IMMEDIATE.
+
+ The 'j' format uses OP and TARGET.
+
+ The 'r' format uses OP, RS, RT, RD, SHAMT and FUNCT.
+
+ The 'b' format uses OP, RS, RT and DELTA.
+
+ The floating point 'i' format uses OP, RS, RT and IMMEDIATE.
+
+ The floating point 'r' format uses OP, FMT, FT, FS, FD and FUNCT.
+
+ A breakpoint instruction uses OP, CODE and SPEC (10 bits of the
+ breakpoint instruction are not defined; Kane says the breakpoint
+ code field in BREAK is 20 bits; yet MIPS assemblers and debuggers
+ only use ten bits).
+
+ The syscall instruction uses SYSCALL.
+
+ The general coprocessor instructions use COPZ. */
