Use the FloatRoundMode enum type introduced in commit 3dede407cc6
("softfloat: Name rounding mode enum") instead of 'unsigned int'.

MSA means 'MIPS SIMD Architecture' and is defined as a Module by
MIPS.
To keep the directory sorted, we use the 'mod' prefix for MIPS
modules. Rename msa_helper.c as mod-msa_helper.c.

move them with the other helpers in 'mod-msa_helper.c'.

Extract 2200 lines from the huge translate.c to a new file,
'mod-msa_translate.c.inc'. As there are too many inter-dependencies
we don't compile it as another object, but keep including it in the
big translate.o. We gain in code maintainability.

Extract 2150 lines from the huge translate.c to a new file,
'mod-dsp_translate.c.inc'. As there are too many inter-
dependencies we don't compile it as another object, but
keep including it in the big translate.o. We gain in code
maintainability.

Extract 1200 lines from the huge translate.c to a new file,
'ase-mips16e_translate.c.inc'. As there are too many inter-
dependencies we don't compile it as another object, but
keep including it in the big translate.o. We gain in code
maintainability.

Extract 3300 lines from the huge translate.c to a new file,
'isa-micromips_translate.c.inc'. As there are too many inter-
dependencies we don't compile it as another object, but
keep including it in the big translate.o. We gain in code
maintainability.

Extract 4800 lines from the huge translate.c to a new file,
'isa-nanomips_translate.c.inc'. As there are too many inter-
dependencies we don't compile it as another object, but
keep including it in the big translate.o. We gain in code
maintainability.

Media eXtension Unit is a SIMD extension from Ingenic.
Extract 2900 lines from the huge translate.c to a new file,
'vendor-xburst-mxu_translate.c.inc'. As there are too many
inter-dependencies we don't compile it as another object,
but keep including it in the big translate.o. We gain in
code maintainability.

- * AN OVERVIEW OF MXU EXTENSION INSTRUCTION SET
- * ============================================
- *
- *
- * MXU (full name: MIPS eXtension/enhanced Unit) is a SIMD extension of MIPS32
- * instructions set. It is designed to fit the needs of signal, graphical and
- * video processing applications. MXU instruction set is used in Xburst family
- * of microprocessors by Ingenic.
- *
- * MXU unit contains 17 registers called X0-X16. X0 is always zero, and X16 is
- * the control register.
- *
- *
- * The notation used in MXU assembler mnemonics
- * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- *
- * Register operands:
- *
- * XRa, XRb, XRc, XRd - MXU registers
- * Rb, Rc, Rd, Rs, Rt - general purpose MIPS registers
- *
- * Non-register operands:
- *
- * aptn1 - 1-bit accumulate add/subtract pattern
- * aptn2 - 2-bit accumulate add/subtract pattern
- * eptn2 - 2-bit execute add/subtract pattern
- * optn2 - 2-bit operand pattern
- * optn3 - 3-bit operand pattern
- * sft4 - 4-bit shift amount
- * strd2 - 2-bit stride amount
- *
- * Prefixes:
- *
- * Level of parallelism: Operand size:
- * S - single operation at a time 32 - word
- * D - two operations in parallel 16 - half word
- * Q - four operations in parallel 8 - byte
- *
- * Operations:
- *
- * ADD - Add or subtract
- * ADDC - Add with carry-in
- * ACC - Accumulate
- * ASUM - Sum together then accumulate (add or subtract)
- * ASUMC - Sum together then accumulate (add or subtract) with carry-in
- * AVG - Average between 2 operands
- * ABD - Absolute difference
- * ALN - Align data
- * AND - Logical bitwise 'and' operation
- * CPS - Copy sign
- * EXTR - Extract bits
- * I2M - Move from GPR register to MXU register
- * LDD - Load data from memory to XRF
- * LDI - Load data from memory to XRF (and increase the address base)
- * LUI - Load unsigned immediate
- * MUL - Multiply
- * MULU - Unsigned multiply
- * MADD - 64-bit operand add 32x32 product
- * MSUB - 64-bit operand subtract 32x32 product
- * MAC - Multiply and accumulate (add or subtract)
- * MAD - Multiply and add or subtract
- * MAX - Maximum between 2 operands
- * MIN - Minimum between 2 operands
- * M2I - Move from MXU register to GPR register
- * MOVZ - Move if zero
- * MOVN - Move if non-zero
- * NOR - Logical bitwise 'nor' operation
- * OR - Logical bitwise 'or' operation
- * STD - Store data from XRF to memory
- * SDI - Store data from XRF to memory (and increase the address base)
- * SLT - Set of less than comparison
- * SAD - Sum of absolute differences
- * SLL - Logical shift left
- * SLR - Logical shift right
- * SAR - Arithmetic shift right
- * SAT - Saturation
- * SFL - Shuffle
- * SCOP - Calculate x’s scope (-1, means x<0; 0, means x==0; 1, means x>0)
- * XOR - Logical bitwise 'exclusive or' operation
- *
- * Suffixes:
- *
- * E - Expand results
- * F - Fixed point multiplication
- * L - Low part result
- * R - Doing rounding
- * V - Variable instead of immediate
- * W - Combine above L and V
- *

+ *
+ * AN OVERVIEW OF MXU EXTENSION INSTRUCTION SET
+ * ============================================
+ *
+ *
+ * MXU (full name: MIPS eXtension/enhanced Unit) is a SIMD extension of MIPS32
+ * instructions set. It is designed to fit the needs of signal, graphical and
+ * video processing applications. MXU instruction set is used in Xburst family
+ * of microprocessors by Ingenic.
+ *
+ * MXU unit contains 17 registers called X0-X16. X0 is always zero, and X16 is
+ * the control register.
+ *
+ *
+ * The notation used in MXU assembler mnemonics
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * Register operands:
+ *
+ * XRa, XRb, XRc, XRd - MXU registers
+ * Rb, Rc, Rd, Rs, Rt - general purpose MIPS registers
+ *
+ * Non-register operands:
+ *
+ * aptn1 - 1-bit accumulate add/subtract pattern
+ * aptn2 - 2-bit accumulate add/subtract pattern
+ * eptn2 - 2-bit execute add/subtract pattern
+ * optn2 - 2-bit operand pattern
+ * optn3 - 3-bit operand pattern
+ * sft4 - 4-bit shift amount
+ * strd2 - 2-bit stride amount
+ *
+ * Prefixes:
+ *
+ * Level of parallelism: Operand size:
+ * S - single operation at a time 32 - word
+ * D - two operations in parallel 16 - half word
+ * Q - four operations in parallel 8 - byte
+ *
+ * Operations:
+ *
+ * ADD - Add or subtract
+ * ADDC - Add with carry-in
+ * ACC - Accumulate
+ * ASUM - Sum together then accumulate (add or subtract)
+ * ASUMC - Sum together then accumulate (add or subtract) with carry-in
+ * AVG - Average between 2 operands
+ * ABD - Absolute difference
+ * ALN - Align data
+ * AND - Logical bitwise 'and' operation
+ * CPS - Copy sign
+ * EXTR - Extract bits
+ * I2M - Move from GPR register to MXU register
+ * LDD - Load data from memory to XRF
+ * LDI - Load data from memory to XRF (and increase the address base)
+ * LUI - Load unsigned immediate
+ * MUL - Multiply
+ * MULU - Unsigned multiply
+ * MADD - 64-bit operand add 32x32 product
+ * MSUB - 64-bit operand subtract 32x32 product
+ * MAC - Multiply and accumulate (add or subtract)
+ * MAD - Multiply and add or subtract
+ * MAX - Maximum between 2 operands
+ * MIN - Minimum between 2 operands
+ * M2I - Move from MXU register to GPR register
+ * MOVZ - Move if zero
+ * MOVN - Move if non-zero
+ * NOR - Logical bitwise 'nor' operation
+ * OR - Logical bitwise 'or' operation
+ * STD - Store data from XRF to memory
+ * SDI - Store data from XRF to memory (and increase the address base)
+ * SLT - Set of less than comparison
+ * SAD - Sum of absolute differences
+ * SLL - Logical shift left
