         operand specifiers.  Change warning generated by 'B' operand
         specifier to reflect its new multi-purpose usage.
 
+        * config/tc-mips.c (mips_set_options): Use ISA_UNKNOWN rather than
+        -1, and update comment.
+        (file_mips_isa): Likewise.
+        (mips_cpu): Use CPU_UNKNOWN rather than -1, and update comment.
+        (ISA_HAS_COPROC_DELAYS, ISA_HAS_64BIT_REGS, gpr_interlocks): Use
+        ISA_* constants rather than hard-coded numbers.
+        (mips_cpu_info): New structure.
+        (mips_cpu_info_table): New table describing CPU and ISA names
+        and numbers.
+        (mips_cpu_info_from_name, mips_cpu_info_from_isa,
+        mips_cpu_info_from_cpu): New functions.
+        (mips_isa_to_str): New function to get string for ISA name.
+        (mips_cpu_to_str): Convert to use mips_cpu_info_from_cpu, and
+        return const char *.
+        (md_begin): Redo CPU and ISA selection logic, using
+        mips_cpu_info_from_*.  Convert to use ISA_* constants rather
+        than hard-coded numbers.
+        (append_insn, mips_emit_delays, macro, macro2): Convert to use
+        ISA_* constants rather than hard-coded numbers.
+        (mips_ip): Convert to use mips_isa_to_str to get ISA name.
+        (md_longopts): Delete OPTION_NO_MIPS32.
+        (md_parse_option): Convert to use ISA_* constants rather than
+        hard-coded numbers.  Make OPTIONS_MIPS32 case treat MIPS32
+        as an ISA.  Delete OPTION_NO_MIPS32 case.  Convert OPTION_MCPU
+        to use strcasecmp to recognize "default" and to use
+        mips_cpu_info_from_name to get CPU numbers from argument.
+        (md_show_usage): Move -mips32 so it's with the rest of the ISA
+        flags.  Change 4Kc, 4Kp and 4Km CPU entries to just be
+        mips32-4k.
+        (s_mipsset): Accept ISA value 32.
+        * doc/as.texinfo: Clean up MIPS options summary slightly,
+        remove -no-mips32.  Add note about -mips4 and -mips32
+        specifying those ISA levels.  Delete -mips32 and -no-mips32
+        cpu flag descriptions.
+        * doc/c-mips.texi: Add -mips32 to list of ISA switches.  Clean
+        up the supported CPU switch list, and replace 4Kc, 4Km, and
+        4Kp entries with a single mips32-4k entry.  Note that you can
+        use ".set mips32".
