MIPS16: Remove "extended" BREAK/SDBBP handling
Remove special casing for the `6' operand code used for the embedded
trap code of the BREAK and the SDBBP instructions to support supposedly
extended forms of these instructions.
According to all versions of the MIPS16 ASE specifications these
instructions are not extensible [1][2][3][4][5][7][8][10][11], and as
from revision 2.50 of the MIPS16e ASE specifications it has been further
clarified what was previously implied, that non-extesiable instructions
when preceded with an EXTEND prefix must cause a Reserved Instruction
exception [5][6][9][10].
Therefore supposedly extended BREAK and SDBBP instructions do not serve
their purpose anymore as they do not cause a Bp and a Debug exception
respectively and supporting these forms in disassembly only causes
confusion.

MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

MIPS16: Handle non-extensible instructions correctly
Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.
