The tests were failing due to md_atof trying to do word-wise endian
switching on the float16 (for little-endian targets sometimes
multi word values have their word order changed).
However since a float16 is only 1 word wide, it would end up writing
incorrect data, as you cannot switch the word order of just one word.
* config/tc-arm.c (md_atof): Add precision check. Formatting.
This is a change to the first published specifications [1][a] but since there is no hardware
out there that uses the old instructions we do not want to support the old variant.
This changes are done based on the latest published specifications [1][b].

Half precision floating point numbers will be encoded using the IEEE 754
half precision floating point format - 16 bits in total, 1 for sign, 5
for exponent and 10 bits of mantissa.
This patch implements the float16 directive for both the IEEE 754 format
and the Arm alternative format for the Arm backend.
The syntax of the directive is:
.float16 <0-n decimal numbers>
e.g.
.float16 12.0
.float16 0.23, 433.1, 0.06
The Arm alternative format is almost identical to the IEEE 754 format,
except that it doesn't encode for NaNs or Infinity (instead an exponent
of 0x1F represents a normalized number in the range 65536 to 131008).
The alternative format is documented in the reference manual:
https://static.docs.arm.com/ddi0487/db/DDI0487D_b_armv8_arm.pdf?_ga=2.72318806.49764181.1561632697-999473562.1560847439
Which format is used is controlled by the .float16_format <format>
directive, where if <format> = ieee, then use the IEEE 754
half-precision format else if <format> = alternative, then use the
Arm alternative format
Or the format can be set on the command line via the -mfp16-format
option that has a similar syntax. -mfp16-format=<ieee|alternative>.
This also fixes the format and it cannot be changed by any directives.
Once the format has been set (either by the command line option or a directive) it cannot be changed,
and any attempts to change it (i.e. with the float16_format directive) will result in a warning and the
line being ignored.
For ELF targets the appropriate EABI attribute will be written out at the end of assembling
if the format has been explicitly specified. If no format has been explicitly specified then no
EABI attributes will be written.
If the format is not explicitly specified then any float16 directives are encoding using the IEEE 754-2008
format by default until the format is fixed or changed with the float16_format directive.

Previously GAS would accept .u32, .u16 and .u8 suffixes to the VQ(R)DMLAH and VQ(R)DMLASH
instructions, however the Armv8.1-M Mainline specification states that these functions only
have signed variations (.s32, .s16 and .s8 suffixes).
This is documented here:
https://static.docs.arm.com/ddi0553/bh/DDI0553B_h_armv8m_arm.pdf?_ga=2.143079093.1892401233.1563295591-999473562.1560847439#page=1183

* testsuite/gas/arm/mve-vqdmlash.d: Remove unsigned instruction tests.
* testsuite/gas/arm/mve-vqdmlash.s: Remove unsigned instruction tests.
opcodes * arm-dis.c: Only accept signed variants of VQ(R)DMLAH and VQ(R)DMLASH
instructions.
The instructions that this change apply to are:
VQDMLADH, VQRDMLADH, VQDMLSDH, VQRDMLSDH
The updated documentation is here: https://static.docs.arm.com/ddi0553/bh/DDI0553B_h_armv8m_arm.pdf
Fixed this by removing the check for this warning from GAS as well as opcodes.
Added testcases to test that the warning is not generated for the instructions that have a 32-bit element size
and the same source and destination operand. Also fixed tests that would previously check for this warning.
gas * config/tc-arm.c (do_mve_vqdmladh): Remove check for UNPREDICTABLE.

* testsuite/gas/arm/mve-vqdmlsdh.d: New tests.
* testsuite/gas/arm/mve-vqdmlsdh.s: New tests.
opcodes * arm-dis.c (is_mve_unpredictable): Stop marking some MVE
instructions as UNPREDICTABLE.
For example, this code is invalid:
smc #0x6951
The code would previously check for and encode for up to 16 bit immediate values, however
this immediate should instead be only a 4 bit value
(as documented herehttps://static.docs.arm.com/ddi0406/c/DDI0406C_C_arm_architecture_reference_manual.pdf ).
Fixed this by adding range checks in the relevant areas and also removing code that would
encode more than the first 4 bits of the immediate (code that is now redundant, as any immediate operand
larger than 0xF would error now anyway).
gas * config/tc-arm.c (do_smc): Add range check for immediate operand.
(do_t_smc): Add range check for immediate operand. Remove
obsolete immediate encoding.
(md_apply_fix): Fix range check. Remove obsolete immediate encoding.

This patch makes changes to the <spec_reg> operand for VMRS and VMSR
instructions as per the Armv8.1-M Mainline.
New <spec_reg> options to support are:
0b0010: FPSCR_nzcvqc, access to FPSCR condition and saturation flags.
0b1100: VPR, privileged only access to the VPR register.
0b1101: P0, access to VPR.P0 predicate fields
0b1110: FPCXT_NS, enables saving and restoring of Non-secure floating
point context.
0b1111: FPCXT_S, enables saving and restoring of Secure floating point
context
