These are lightweight utilities which should only be called by parse_operands
|
2012-08-13 16:52:54 +02:00
|
|
|
|
and other parsers. GAS processes each assembly line by parsing it against
|
|
|
|
|
instruction template(s), in the case of multiple templates (for the same
|
|
|
|
|
mnemonic name), those templates are tried one by one until one succeeds or
|
|
|
|
|
all fail. An assembly line may fail a few templates before being
|
|
|
|
|
successfully parsed; an error saved here in most cases is not a user error
|
|
|
|
|
but an error indicating the current template is not the right template.
|
|
|
|
|
Therefore it is very important that errors can be saved at a low cost during
|
|
|
|
|
the parsing; we don't want to slow down the whole parsing by recording
|
|
|
|
|
non-user errors in detail.
|
|
|
|
|
|
2017-01-23 16:23:07 +01:00
|
|
|
|
Remember that the objective is to help GAS pick up the most appropriate
|
2012-08-13 16:52:54 +02:00
|
|
|
|
error message in the case of multiple templates, e.g. FMOV which has 8
|

|
|
|
templates. */

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the

in future if necessary.

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp

makes the changes easier to read.

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.

register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

[aarch64] Add support for pointer authentication B key
Armv8.3-A has another key used in pointer authentication called the
B-key (other than the A-key that is already supported). In order for
stack unwinders to work it is necessary to be able to identify frames
that have been signed with the B-key rather than the A-key and it was
felt that keeping this as an augmentation character in the CIE was the
best bet. The DWARF extensions for ARM therefore propose to add a new
augmentation character 'B' to the CIE augmentation string and the
corresponding cfi directive ".cfi_b_key_frame". I've made the relevant
changes to GAS and LD to add support for B-key unwinding, which required
modifying LD to check for 'B' in the augmentation string, adding the
".cfi_b_key_frame" directive to GAS and adding a "pauth_key" field to
GAS's fde_entry and cie_entry structs.
The pointer authentication instructions will behave as NOPs on
architectures that don't support them, and so a check for the
architecture being assembled for is not necessary since there will be no
behavioural difference between augmentation strings with and without the
'B' character on such architectures.

[AArch64][SVE 07/32] Replace hard-coded uses of REG_TYPE_R_Z_BHSDQ_V
To remove parsing ambiguities and to avoid register names being
accidentally added to the symbol table, the immediate parsing
routines reject things like:
.equ x0, 0
add v0.4s, v0.4s, x0
An explicit '#' must be used instead:
.equ x0, 0
add v0.4s, v0.4s, #x0
Of course, it wasn't possible to predict what other register
names might be added in future, so this behaviour was restricted
to the register names that were defined at the time. For backwards
compatibility, we should continue to allow things like:
.equ p0, 0
add v0.4s, v0.4s, p0
even though p0 is now an SVE register.
However, it seems reasonable to extend the x0 behaviour above to
SVE registers when parsing SVE instructions, especially since none
of the SVE immediate formats are relocatable. Doing so removes the
same parsing ambiguity for SVE instructions as the x0 behaviour removes
for base AArch64 instructions.
As a prerequisite, we then need to be able to tell the parsing routines
which registers to reject. This patch changes the interface to make
that possible, although the set of rejected registers doesn't change
at this stage.

[AArch64][SVE 07/32] Replace hard-coded uses of REG_TYPE_R_Z_BHSDQ_V
To remove parsing ambiguities and to avoid register names being
accidentally added to the symbol table, the immediate parsing
routines reject things like:
.equ x0, 0
add v0.4s, v0.4s, x0
An explicit '#' must be used instead:
.equ x0, 0
add v0.4s, v0.4s, #x0
Of course, it wasn't possible to predict what other register
names might be added in future, so this behaviour was restricted
to the register names that were defined at the time. For backwards
compatibility, we should continue to allow things like:
.equ p0, 0
add v0.4s, v0.4s, p0
even though p0 is now an SVE register.
However, it seems reasonable to extend the x0 behaviour above to
SVE registers when parsing SVE instructions, especially since none
of the SVE immediate formats are relocatable. Doing so removes the
same parsing ambiguity for SVE instructions as the x0 behaviour removes
for base AArch64 instructions.
As a prerequisite, we then need to be able to tell the parsing routines
which registers to reject. This patch changes the interface to make
that possible, although the set of rejected registers doesn't change
at this stage.

[AArch64][SVE 26/32] Add SVE MUL VL addressing modes
This patch adds support for addresses of the form:
[<base>, #<offset>, MUL VL]
This involves adding a new AARCH64_MOD_MUL_VL modifier, which is
why I split it out from the other addressing modes.
For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, .... The patch
therefore extends value_aligned_p to handle non-power-of-2 alignments.
include/
* opcode/aarch64.h (AARCH64_OPND_SVE_ADDR_RI_S4xVL): New aarch64_opnd.
(AARCH64_OPND_SVE_ADDR_RI_S4x2xVL, AARCH64_OPND_SVE_ADDR_RI_S4x3xVL)

(AARCH64_OPND_SVE_ADDR_RI_S9xVL): Likewise.
(AARCH64_MOD_MUL_VL): New aarch64_modifier_kind.
opcodes/
* aarch64-tbl.h (AARCH64_OPERANDS): Add entries for new MUL VL
operands.
* aarch64-opc.c (aarch64_operand_modifiers): Initialize
the AARCH64_MOD_MUL_VL entry.
(value_aligned_p): Cope with non-power-of-two alignments.
(operand_general_constraint_met_p): Handle the new MUL VL addresses.
(print_immediate_offset_address): Likewise.
(aarch64_print_operand): Likewise.
* aarch64-opc-2.c: Regenerate.
* aarch64-asm.h (ins_sve_addr_ri_s4xvl, ins_sve_addr_ri_s6xvl)

[AArch64][SVE 24/32] Add AARCH64_OPND_SVE_PATTERN_SCALED
Some SVE instructions count the number of elements in a given vector
pattern and allow a scale factor of [1, 16] to be applied to the result.
This scale factor is written ", MUL #n", where "MUL" is a new operator.
E.g.:
UQINCD X0, POW2, MUL #2
This patch adds support for this kind of operand.
All existing operators were shifts of some kind, so there was a natural
range of [0, 63] regardless of context. This was then narrowered further
by later checks (e.g. to [0, 31] when used for 32-bit values).
In contrast, MUL doesn't really have a natural context-independent range.
Rather than pick one arbitrarily, it seemed better to make the "shift"
amount a full 64-bit value and leave the range test to the usual
operand-checking code. I've rearranged the fields of aarch64_opnd_info
so that this doesn't increase the size of the structure (although I don't
think its size is critical anyway).

[AArch64][SVE 26/32] Add SVE MUL VL addressing modes
This patch adds support for addresses of the form:
[<base>, #<offset>, MUL VL]
This involves adding a new AARCH64_MOD_MUL_VL modifier, which is
why I split it out from the other addressing modes.
For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, .... The patch
therefore extends value_aligned_p to handle non-power-of-2 alignments.

[AArch64][SVE 26/32] Add SVE MUL VL addressing modes
This patch adds support for addresses of the form:
[<base>, #<offset>, MUL VL]
This involves adding a new AARCH64_MOD_MUL_VL modifier, which is
why I split it out from the other addressing modes.
For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, .... The patch
therefore extends value_aligned_p to handle non-power-of-2 alignments.

[AArch64][SVE 24/32] Add AARCH64_OPND_SVE_PATTERN_SCALED
Some SVE instructions count the number of elements in a given vector
pattern and allow a scale factor of [1, 16] to be applied to the result.
This scale factor is written ", MUL #n", where "MUL" is a new operator.
E.g.:
UQINCD X0, POW2, MUL #2
This patch adds support for this kind of operand.
All existing operators were shifts of some kind, so there was a natural
range of [0, 63] regardless of context. This was then narrowered further
by later checks (e.g. to [0, 31] when used for 32-bit values).
In contrast, MUL doesn't really have a natural context-independent range.
Rather than pick one arbitrarily, it seemed better to make the "shift"
amount a full 64-bit value and leave the range test to the usual
operand-checking code. I've rearranged the fields of aarch64_opnd_info
so that this doesn't increase the size of the structure (although I don't
think its size is critical anyway).

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

[AArch64][SVE 26/32] Add SVE MUL VL addressing modes
This patch adds support for addresses of the form:
[<base>, #<offset>, MUL VL]
This involves adding a new AARCH64_MOD_MUL_VL modifier, which is
why I split it out from the other addressing modes.
For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, .... The patch
therefore extends value_aligned_p to handle non-power-of-2 alignments.

[AArch64][SVE 26/32] Add SVE MUL VL addressing modes
This patch adds support for addresses of the form:
[<base>, #<offset>, MUL VL]
This involves adding a new AARCH64_MOD_MUL_VL modifier, which is
why I split it out from the other addressing modes.
For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, .... The patch
therefore extends value_aligned_p to handle non-power-of-2 alignments.

[AArch64][SVE 26/32] Add SVE MUL VL addressing modes
This patch adds support for addresses of the form:
[<base>, #<offset>, MUL VL]
This involves adding a new AARCH64_MOD_MUL_VL modifier, which is
why I split it out from the other addressing modes.
For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, .... The patch
therefore extends value_aligned_p to handle non-power-of-2 alignments.

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

[AArch64][SVE 12/32] Remove boolean parameters from parse_address_main
In the review of the original version of this series, Richard didn't
like the use of boolean parameters to parse_address_main. I think we
can just get rid of them and leave the callers to check the addressing
modes. As it happens, the handling of ADDR_SIMM9{,_2} already did this
for relocation operators (i.e. it used parse_address_reloc and then
rejected relocations).
The callers are already set up to reject invalid register post-indexed
addressing, so we can simply remove the accept_reg_post_index parameter
without adding any more checks. This again creates a corner case where:
.equ x2, 1
ldr w0, [x1], x2
was previously an acceptable way of writing "ldr w0, [x1], #1" but
is now rejected.
Removing the "reloc" parameter means that two cases need to check
explicitly for relocation operators.
ADDR_SIMM9_2 appers to be unused. I'll send a separate patch
to remove it.
This patch makes parse_address temporarily equivalent to
parse_address_main, but later patches in the series will need
to keep the distinction.

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

[AArch64][SVE 12/32] Remove boolean parameters from parse_address_main
In the review of the original version of this series, Richard didn't
like the use of boolean parameters to parse_address_main. I think we
can just get rid of them and leave the callers to check the addressing
modes. As it happens, the handling of ADDR_SIMM9{,_2} already did this
for relocation operators (i.e. it used parse_address_reloc and then
rejected relocations).
The callers are already set up to reject invalid register post-indexed
addressing, so we can simply remove the accept_reg_post_index parameter
without adding any more checks. This again creates a corner case where:
.equ x2, 1
ldr w0, [x1], x2
was previously an acceptable way of writing "ldr w0, [x1], #1" but
is now rejected.
Removing the "reloc" parameter means that two cases need to check
explicitly for relocation operators.
ADDR_SIMM9_2 appers to be unused. I'll send a separate patch
to remove it.
This patch makes parse_address temporarily equivalent to
parse_address_main, but later patches in the series will need
to keep the distinction.

[AArch64][SVE 26/32] Add SVE MUL VL addressing modes
This patch adds support for addresses of the form:
[<base>, #<offset>, MUL VL]
This involves adding a new AARCH64_MOD_MUL_VL modifier, which is

For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, .... The patch

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated

makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the

For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better

[AArch64][SVE 12/32] Remove boolean parameters from parse_address_main
In the review of the original version of this series, Richard didn't
like the use of boolean parameters to parse_address_main. I think we
can just get rid of them and leave the callers to check the addressing
modes. As it happens, the handling of ADDR_SIMM9{,_2} already did this
for relocation operators (i.e. it used parse_address_reloc and then
rejected relocations).
The callers are already set up to reject invalid register post-indexed
addressing, so we can simply remove the accept_reg_post_index parameter
without adding any more checks. This again creates a corner case where:
.equ x2, 1
ldr w0, [x1], x2
was previously an acceptable way of writing "ldr w0, [x1], #1" but
is now rejected.
Removing the "reloc" parameter means that two cases need to check
explicitly for relocation operators.
ADDR_SIMM9_2 appers to be unused. I'll send a separate patch
to remove it.
This patch makes parse_address temporarily equivalent to
parse_address_main, but later patches in the series will need
to keep the distinction.

[AArch64][SVE 26/32] Add SVE MUL VL addressing modes
This patch adds support for addresses of the form:
[<base>, #<offset>, MUL VL]
This involves adding a new AARCH64_MOD_MUL_VL modifier, which is
why I split it out from the other addressing modes.
For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, .... The patch

[AArch64][SVE 26/32] Add SVE MUL VL addressing modes
This patch adds support for addresses of the form:
[<base>, #<offset>, MUL VL]
This involves adding a new AARCH64_MOD_MUL_VL modifier, which is
why I split it out from the other addressing modes.
For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, .... The patch
therefore extends value_aligned_p to handle non-power-of-2 alignments.

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

[PATCH, BINUTILS, AARCH64, 7/9] Add BTI instruction
This patch is part of the patch series to add support for ARMv8.5-A
extensions.
(https://developer.arm.com/products/architecture/cpu-architecture/a-profile/docs/ddi0596/a/a64-base-instructions-alphabetic-order/bti-branch-target-identification)
The Branch Target Identification instructions (BTI) are allocated to
existing HINT space, using HINT numbers 32, 34, 36, 38, such that
bits[7:6] of the instruction identify the compatibility of the BTI
instruction to different branches.
BTI {<targets>}
where <targets> one of the following, specifying which type of
indirection is allowed:
j : Can be a target of any BR Xn isntruction.
c : Can be a target of any BLR Xn and BR {X16|X17}.
jc: Can be a target of any free branch.
A BTI instruction without any <targets> is the strictest of all and
can not be a target of nay free branch.

Modify AArch64 Assembly and disassembly functions to be able to fail and report why.
This patch if the first patch in a series to add the ability to add constraints
to system registers that an instruction must adhere to in order for the register
to be usable with that instruction.
These constraints can also be used to disambiguate between registers with the
same encoding during disassembly.
This patch adds a new flags entry in the sysreg structures and ensures it is
filled in and read out during assembly/disassembly. It also adds the ability for
the assemble and disassemble functions to be able to gracefully fail and re-use
the existing error reporting infrastructure.
The return type of these functions are changed to a boolean to denote success or
failure and the error structure is passed around to them. This requires
aarch64-gen changes so a lot of the changes here are just mechanical.

to system registers that an instruction must adhere to in order for the register
to be usable with that instruction.
These constraints can also be used to disambiguate between registers with the
same encoding during disassembly.
This patch adds a new flags entry in the sysreg structures and ensures it is
filled in and read out during assembly/disassembly. It also adds the ability for
the assemble and disassemble functions to be able to gracefully fail and re-use
the existing error reporting infrastructure.
The return type of these functions are changed to a boolean to denote success or
failure and the error structure is passed around to them. This requires
aarch64-gen changes so a lot of the changes here are just mechanical.

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

[AArch64][SVE 07/32] Replace hard-coded uses of REG_TYPE_R_Z_BHSDQ_V
To remove parsing ambiguities and to avoid register names being
accidentally added to the symbol table, the immediate parsing
routines reject things like:
.equ x0, 0
add v0.4s, v0.4s, x0
An explicit '#' must be used instead:
.equ x0, 0
add v0.4s, v0.4s, #x0
Of course, it wasn't possible to predict what other register
names might be added in future, so this behaviour was restricted
to the register names that were defined at the time. For backwards
compatibility, we should continue to allow things like:
.equ p0, 0
add v0.4s, v0.4s, p0
even though p0 is now an SVE register.
However, it seems reasonable to extend the x0 behaviour above to
SVE registers when parsing SVE instructions, especially since none
of the SVE immediate formats are relocatable. Doing so removes the
same parsing ambiguity for SVE instructions as the x0 behaviour removes
for base AArch64 instructions.
As a prerequisite, we then need to be able to tell the parsing routines
which registers to reject. This patch changes the interface to make
that possible, although the set of rejected registers doesn't change
at this stage.

The string representation of the corrected instruction and other

valid variants are generated by
|
|
|
|
|
|
|
|
|
|
1) obtaining the intermediate representation of the erroneous

|
instruction;
|
|
|
|
|
2) manipulating the IR, e.g. replacing the operand qualifier;
|
|
|
|
|
3) printing out the instruction by calling the printer functions
|
|
|
|
|
shared with the disassembler.
|
|
|
|
|
|
|
|
|
|
The limitation of this method is that the exact input assembly
|
|
|
|
|
line cannot be accurately reproduced in some cases, for example an
|
|
|
|
|
optional operand present in the actual assembly line will be
|
|
|
|
|
omitted in the output; likewise for the optional syntax rules,
|
|
|
|
|
e.g. the # before the immediate. Another limitation is that the
|
|
|
|
|
assembly symbols and relocation operations in the assembly line
|
|
|
|
|
currently cannot be printed out in the error report. Last but not
|
|
|
|
|
least, when there is other error(s) co-exist with this error, the
|
|
|
|
|
'corrected' instruction may be still incorrect, e.g. given
|
|
|
|
|
'ldnp h0,h1,[x0,#6]!'
|
|
|
|
|
this diagnosis will provide the version:
|
|
|
|
|
'ldnp s0,s1,[x0,#6]!'
|
|

which is still not right. */

[AArch64][SVE 20/32] Add support for tied operands
SVE has some instructions in which the same register appears twice
in the assembly string, once as an input and once as an output.
This patch adds a general mechanism for that.
The patch needs to add new information to the instruction entries.
One option would have been to extend the flags field of the opcode
to 64 bits (since we already rely on 64-bit integers being available
on the host). However, the *_INSN macros mean that it's easy to add
new information as top-level fields without affecting the existing
table entries too much. Going for that option seemed to give slightly
neater code.
include/
* opcode/aarch64.h (aarch64_opcode): Add a tied_operand field.
(AARCH64_OPDE_UNTIED_OPERAND): New aarch64_operand_error_kind.

essentially, because each operand template is tried recursively you may

prevents us from printing errors that are not appropriate, since we did

match a condition, but it also has warnings that it wants to print. */

[AArch64] Add SVE condition codes
SVE defines new names for existing NZCV conditions, to reflect the
result of instructions like PTEST. This patch adds support for these
names.
The patch also adds comments to the disassembly output to show the
alternative names of a condition code. For example:
cinv x0, x1, cc
becomes:
cinv x0, x1, cc // cc = lo, ul, last
and:
b.cc f0 <...>
becomes:
b.cc f0 <...> // b.lo, b.ul, b.last
Doing this for the SVE names follows the practice recommended by the
SVE specification and is definitely useful when reading SVE code.
If the feeling is that it's too distracting elsewhere, we could add
an option to turn it off.

alternative names of a condition code. For example:
cinv x0, x1, cc
becomes:
cinv x0, x1, cc // cc = lo, ul, last
and:
b.cc f0 <...>
becomes:
b.cc f0 <...> // b.lo, b.ul, b.last
Doing this for the SVE names follows the practice recommended by the
SVE specification and is definitely useful when reading SVE code.
If the feeling is that it's too distracting elsewhere, we could add
an option to turn it off.

[AArch64] Add SVE condition codes
SVE defines new names for existing NZCV conditions, to reflect the
result of instructions like PTEST. This patch adds support for these
names.
The patch also adds comments to the disassembly output to show the

cinv x0, x1, cc

[BINUTILS, AArch64, 2/2] Update Store Allocation Tag instructions
This patch updates the Store allocation tags instructions in
Armv8.5-A Memory Tagging Extension. This is part of the changes
that have been introduced recently in the 00bet10 release
All of these instructions have an updated register operand (Xt -> <Xt|SP>)
- STG <Xt|SP>, [<Xn|SP>, #<simm>]
- STG <Xt|SP>, [<Xn|SP>, #<simm>]!
- STG <Xt|SP>, [<Xn|SP>], #<simm>
- STZG <Xt|SP>, [<Xn|SP>, #<simm>]
- STZG <Xt|SP>, [<Xn|SP>, #<simm>]!
- STZG <Xt|SP>, [<Xn|SP>], #<simm>
- ST2G <Xt|SP>, [<Xn|SP>, #<simm>]
- ST2G <Xt|SP>, [<Xn|SP>, #<simm>]!
- ST2G <Xt|SP>, [<Xn|SP>], #<simm>
- STZ2G <Xt|SP>, [<Xn|SP>, #<simm>]
- STZ2G <Xt|SP>, [<Xn|SP>, #<simm>]!
- STZ2G <Xt|SP>, [<Xn|SP>], #<simm>
In order to accept <Rt|SP> a new operand type Rt_SP is introduced which has
the same field as FLD_Rt but follows other semantics of Rn_SP.

Fix AArch64 encodings for by element instructions.
Some instructions in Armv8-a place a limitation on FP16 registers that can be
used as the register from which to select an element from.
e.g. fmla restricts Rm to 4 bits when using an FP16 register. This restriction
does not apply for all instructions, e.g. fcmla does not have this restriction
as it gets an extra bit from the M field.
Unfortunately, this restriction to S_H was added for all _Em operands before,
meaning for a large number of instructions you couldn't use the full register
file.
This fixes the issue by introducing a new operand _Em16 which applies this
restriction only when paired with S_H and leaves the _Em and the other
qualifiers for _Em16 unbounded (i.e. using the full 5 bit range).
Also the patch updates all instructions that should be affected by this.

[AArch64][SVE 24/32] Add AARCH64_OPND_SVE_PATTERN_SCALED
Some SVE instructions count the number of elements in a given vector
pattern and allow a scale factor of [1, 16] to be applied to the result.
This scale factor is written ", MUL #n", where "MUL" is a new operator.
E.g.:
UQINCD X0, POW2, MUL #2
This patch adds support for this kind of operand.
All existing operators were shifts of some kind, so there was a natural
range of [0, 63] regardless of context. This was then narrowered further
by later checks (e.g. to [0, 31] when used for 32-bit values).
In contrast, MUL doesn't really have a natural context-independent range.
Rather than pick one arbitrarily, it seemed better to make the "shift"
amount a full 64-bit value and leave the range test to the usual
operand-checking code. I've rearranged the fields of aarch64_opnd_info
so that this doesn't increase the size of the structure (although I don't
think its size is critical anyway).

[PATCH, BINUTILS, AARCH64, 7/9] Add BTI instruction
This patch is part of the patch series to add support for ARMv8.5-A
extensions.
(https://developer.arm.com/products/architecture/cpu-architecture/a-profile/docs/ddi0596/a/a64-base-instructions-alphabetic-order/bti-branch-target-identification)
The Branch Target Identification instructions (BTI) are allocated to
existing HINT space, using HINT numbers 32, 34, 36, 38, such that
bits[7:6] of the instruction identify the compatibility of the BTI
instruction to different branches.
BTI {<targets>}
where <targets> one of the following, specifying which type of
indirection is allowed:
j : Can be a target of any BR Xn isntruction.
c : Can be a target of any BLR Xn and BR {X16|X17}.
jc: Can be a target of any free branch.
A BTI instruction without any <targets> is the strictest of all and
can not be a target of nay free branch.

[AArch64][SVE 07/32] Replace hard-coded uses of REG_TYPE_R_Z_BHSDQ_V
To remove parsing ambiguities and to avoid register names being
accidentally added to the symbol table, the immediate parsing
routines reject things like:
.equ x0, 0
add v0.4s, v0.4s, x0
An explicit '#' must be used instead:
.equ x0, 0
add v0.4s, v0.4s, #x0
Of course, it wasn't possible to predict what other register
names might be added in future, so this behaviour was restricted
to the register names that were defined at the time. For backwards
compatibility, we should continue to allow things like:
.equ p0, 0
add v0.4s, v0.4s, p0
even though p0 is now an SVE register.
However, it seems reasonable to extend the x0 behaviour above to
SVE registers when parsing SVE instructions, especially since none
of the SVE immediate formats are relocatable. Doing so removes the
same parsing ambiguity for SVE instructions as the x0 behaviour removes
for base AArch64 instructions.
As a prerequisite, we then need to be able to tell the parsing routines
which registers to reject. This patch changes the interface to make
that possible, although the set of rejected registers doesn't change
at this stage.

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

[BINUTILS, AArch64, 2/2] Update Store Allocation Tag instructions
This patch updates the Store allocation tags instructions in
Armv8.5-A Memory Tagging Extension. This is part of the changes
that have been introduced recently in the 00bet10 release
All of these instructions have an updated register operand (Xt -> <Xt|SP>)
- STG <Xt|SP>, [<Xn|SP>, #<simm>]
- STG <Xt|SP>, [<Xn|SP>, #<simm>]!
- STG <Xt|SP>, [<Xn|SP>], #<simm>
- STZG <Xt|SP>, [<Xn|SP>, #<simm>]
- STZG <Xt|SP>, [<Xn|SP>, #<simm>]!
- STZG <Xt|SP>, [<Xn|SP>], #<simm>
- ST2G <Xt|SP>, [<Xn|SP>, #<simm>]
- ST2G <Xt|SP>, [<Xn|SP>, #<simm>]!
- ST2G <Xt|SP>, [<Xn|SP>], #<simm>
- STZ2G <Xt|SP>, [<Xn|SP>, #<simm>]
- STZ2G <Xt|SP>, [<Xn|SP>, #<simm>]!
- STZ2G <Xt|SP>, [<Xn|SP>], #<simm>
In order to accept <Rt|SP> a new operand type Rt_SP is introduced which has
the same field as FLD_Rt but follows other semantics of Rn_SP.

Fix AArch64 encodings for by element instructions.
Some instructions in Armv8-a place a limitation on FP16 registers that can be
used as the register from which to select an element from.
e.g. fmla restricts Rm to 4 bits when using an FP16 register. This restriction
does not apply for all instructions, e.g. fcmla does not have this restriction
as it gets an extra bit from the M field.
Unfortunately, this restriction to S_H was added for all _Em operands before,
meaning for a large number of instructions you couldn't use the full register
file.
This fixes the issue by introducing a new operand _Em16 which applies this
restriction only when paired with S_H and leaves the _Em and the other
qualifiers for _Em16 unbounded (i.e. using the full 5 bit range).
Also the patch updates all instructions that should be affected by this.

[AArch64][SVE 27/32] Add SVE integer immediate operands
This patch adds the new SVE integer immediate operands. There are
three kinds:
- simple signed and unsigned ranges, but with new widths and positions.
- 13-bit logical immediates. These have the same form as in base AArch64,
but at a different bit position.
In the case of the "MOV Zn.<T>, #<limm>" alias of DUPM, the logical
immediate <limm> is not allowed to be a valid DUP immediate, since DUP
is preferred over DUPM for constants that both instructions can handle.
- a new 9-bit arithmetic immediate, of the form "<imm8>{, LSL #8}".
In some contexts the operand is signed and in others it's unsigned.
As an extension, we allow shifted immediates to be written as a single
integer, e.g. "#256" is equivalent to "#1, LSL #8". We also use the
shiftless form as the preferred disassembly, except for the special
case of "#0, LSL #8" (a redundant encoding of 0).

[AArch64][SVE 27/32] Add SVE integer immediate operands
This patch adds the new SVE integer immediate operands. There are
three kinds:
- simple signed and unsigned ranges, but with new widths and positions.
- 13-bit logical immediates. These have the same form as in base AArch64,
but at a different bit position.
In the case of the "MOV Zn.<T>, #<limm>" alias of DUPM, the logical
immediate <limm> is not allowed to be a valid DUP immediate, since DUP
is preferred over DUPM for constants that both instructions can handle.
- a new 9-bit arithmetic immediate, of the form "<imm8>{, LSL #8}".
In some contexts the operand is signed and in others it's unsigned.
As an extension, we allow shifted immediates to be written as a single
integer, e.g. "#256" is equivalent to "#1, LSL #8". We also use the
shiftless form as the preferred disassembly, except for the special
case of "#0, LSL #8" (a redundant encoding of 0).

[AArch64] Add ARMv8.3 FCMLA and FCADD instructions
Add support for FCMLA and FCADD complex arithmetic SIMD instructions.
FCMLA has an indexed element variant where the index range has to be
treated specially because a complex number takes two elements and the
indexed vector size depends on the other operands.
These complex number SIMD instructions are part of ARMv8.3

[AArch64][SVE 24/32] Add AARCH64_OPND_SVE_PATTERN_SCALED
Some SVE instructions count the number of elements in a given vector
pattern and allow a scale factor of [1, 16] to be applied to the result.
This scale factor is written ", MUL #n", where "MUL" is a new operator.
E.g.:
UQINCD X0, POW2, MUL #2
This patch adds support for this kind of operand.
All existing operators were shifts of some kind, so there was a natural
range of [0, 63] regardless of context. This was then narrowered further
by later checks (e.g. to [0, 31] when used for 32-bit values).
In contrast, MUL doesn't really have a natural context-independent range.
Rather than pick one arbitrarily, it seemed better to make the "shift"
amount a full 64-bit value and leave the range test to the usual
operand-checking code. I've rearranged the fields of aarch64_opnd_info
so that this doesn't increase the size of the structure (although I don't
think its size is critical anyway).

[AArch64][SVE 07/32] Replace hard-coded uses of REG_TYPE_R_Z_BHSDQ_V
To remove parsing ambiguities and to avoid register names being
accidentally added to the symbol table, the immediate parsing
routines reject things like:
.equ x0, 0
add v0.4s, v0.4s, x0
An explicit '#' must be used instead:
.equ x0, 0
add v0.4s, v0.4s, #x0
Of course, it wasn't possible to predict what other register
names might be added in future, so this behaviour was restricted
to the register names that were defined at the time. For backwards
compatibility, we should continue to allow things like:
.equ p0, 0
add v0.4s, v0.4s, p0
even though p0 is now an SVE register.
However, it seems reasonable to extend the x0 behaviour above to
SVE registers when parsing SVE instructions, especially since none
of the SVE immediate formats are relocatable. Doing so removes the
same parsing ambiguity for SVE instructions as the x0 behaviour removes
for base AArch64 instructions.
As a prerequisite, we then need to be able to tell the parsing routines
which registers to reject. This patch changes the interface to make
that possible, although the set of rejected registers doesn't change
at this stage.

[AArch64][SVE 07/32] Replace hard-coded uses of REG_TYPE_R_Z_BHSDQ_V
To remove parsing ambiguities and to avoid register names being
accidentally added to the symbol table, the immediate parsing
routines reject things like:
.equ x0, 0
add v0.4s, v0.4s, x0
An explicit '#' must be used instead:
.equ x0, 0
add v0.4s, v0.4s, #x0
Of course, it wasn't possible to predict what other register
names might be added in future, so this behaviour was restricted
to the register names that were defined at the time. For backwards
compatibility, we should continue to allow things like:
.equ p0, 0
add v0.4s, v0.4s, p0
even though p0 is now an SVE register.
However, it seems reasonable to extend the x0 behaviour above to
SVE registers when parsing SVE instructions, especially since none
of the SVE immediate formats are relocatable. Doing so removes the
same parsing ambiguity for SVE instructions as the x0 behaviour removes
for base AArch64 instructions.
As a prerequisite, we then need to be able to tell the parsing routines
which registers to reject. This patch changes the interface to make
that possible, although the set of rejected registers doesn't change
at this stage.

[AArch64] Add SVE condition codes
SVE defines new names for existing NZCV conditions, to reflect the
result of instructions like PTEST. This patch adds support for these
names.
The patch also adds comments to the disassembly output to show the
alternative names of a condition code. For example:
cinv x0, x1, cc
becomes:
cinv x0, x1, cc // cc = lo, ul, last
and:
b.cc f0 <...>
becomes:
b.cc f0 <...> // b.lo, b.ul, b.last
Doing this for the SVE names follows the practice recommended by the
SVE specification and is definitely useful when reading SVE code.
If the feeling is that it's too distracting elsewhere, we could add
an option to turn it off.

[AArch64][SVE 12/32] Remove boolean parameters from parse_address_main
In the review of the original version of this series, Richard didn't
like the use of boolean parameters to parse_address_main. I think we
can just get rid of them and leave the callers to check the addressing
modes. As it happens, the handling of ADDR_SIMM9{,_2} already did this
for relocation operators (i.e. it used parse_address_reloc and then
rejected relocations).
The callers are already set up to reject invalid register post-indexed
addressing, so we can simply remove the accept_reg_post_index parameter
without adding any more checks. This again creates a corner case where:
.equ x2, 1
ldr w0, [x1], x2
was previously an acceptable way of writing "ldr w0, [x1], #1" but
is now rejected.
Removing the "reloc" parameter means that two cases need to check
explicitly for relocation operators.
ADDR_SIMM9_2 appers to be unused. I'll send a separate patch
to remove it.
This patch makes parse_address temporarily equivalent to
parse_address_main, but later patches in the series will need
to keep the distinction.

[AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things. It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.
SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough. It's more convenient to pass the type of register around as
a qualifier instead.
As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.
Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted. We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants. This is easier to do if the function returns the
reg_entry rather than just the register number.
This does create a corner case where:
.equ sp, 1
ldr w0, [x0, sp]
was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:
.equ sp, 1
add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.

add x0, x1, sp
To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE. The next patch also relies on this.
Finally, aarcch64_check_reg_type was written in a pretty
conservative way. It should always be equivalent to a single
bit test.
gas/
* config/tc-aarch64.c (REG_TYPE_R_Z, REG_TYPE_R_SP): New register
types.
(get_reg_expected_msg): Handle them and REG_TYPE_R64_SP.
(aarch64_check_reg_type): Simplify.
(aarch64_reg_parse_32_64): Return the reg_entry instead of the
register number. Return the type as a qualifier rather than an
"isreg32" boolean. Remove reject_sp, reject_rz and isregzero
parameters.
(parse_shifter_operand): Update call to aarch64_parse_32_64_reg.
Use get_reg_expected_msg.
(parse_address_main): Likewise. Use aarch64_check_reg_type.
(po_int_reg_or_fail): Replace reject_sp and reject_rz parameters
with a reg_type parameter. Update call to aarch64_parse_32_64_reg.
Use aarch64_check_reg_type to test the result.
(parse_operands): Update after the above changes. Parse ADDR_SIMPLE
addresses normally before enforcing the syntax restrictions.
* testsuite/gas/aarch64/diagnostic.s: Add tests for a post-index
zero register and for a stack pointer index.
* testsuite/gas/aarch64/diagnostic.l: Update accordingly.
Also update existing diagnostic messages after the above changes.
* testsuite/gas/aarch64/illegal-lse.l: Update the error message
for 32-bit register bases.

[AArch64][SVE 12/32] Remove boolean parameters from parse_address_main
In the review of the original version of this series, Richard didn't
like the use of boolean parameters to parse_address_main. I think we
can just get rid of them and leave the callers to check the addressing
modes. As it happens, the handling of ADDR_SIMM9{,_2} already did this
for relocation operators (i.e. it used parse_address_reloc and then
rejected relocations).
The callers are already set up to reject invalid register post-indexed
addressing, so we can simply remove the accept_reg_post_index parameter
without adding any more checks. This again creates a corner case where:
.equ x2, 1
ldr w0, [x1], x2
was previously an acceptable way of writing "ldr w0, [x1], #1" but
is now rejected.
Removing the "reloc" parameter means that two cases need to check
explicitly for relocation operators.
ADDR_SIMM9_2 appers to be unused. I'll send a separate patch
to remove it.
This patch makes parse_address temporarily equivalent to
parse_address_main, but later patches in the series will need
to keep the distinction.

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

[AArch64][SVE 12/32] Remove boolean parameters from parse_address_main
In the review of the original version of this series, Richard didn't
like the use of boolean parameters to parse_address_main. I think we
can just get rid of them and leave the callers to check the addressing
modes. As it happens, the handling of ADDR_SIMM9{,_2} already did this
for relocation operators (i.e. it used parse_address_reloc and then
rejected relocations).
The callers are already set up to reject invalid register post-indexed
addressing, so we can simply remove the accept_reg_post_index parameter
without adding any more checks. This again creates a corner case where:
.equ x2, 1
ldr w0, [x1], x2
was previously an acceptable way of writing "ldr w0, [x1], #1" but
is now rejected.
Removing the "reloc" parameter means that two cases need to check
explicitly for relocation operators.
ADDR_SIMM9_2 appers to be unused. I'll send a separate patch
to remove it.
This patch makes parse_address temporarily equivalent to
parse_address_main, but later patches in the series will need
to keep the distinction.

accept_reg_post_index parameters. Parse relocations and register

[AArch64][SVE 26/32] Add SVE MUL VL addressing modes
This patch adds support for addresses of the form:
[<base>, #<offset>, MUL VL]
This involves adding a new AARCH64_MOD_MUL_VL modifier, which is
why I split it out from the other addressing modes.
For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, .... The patch

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

[AArch64][SVE 26/32] Add SVE MUL VL addressing modes
This patch adds support for addresses of the form:
[<base>, #<offset>, MUL VL]
This involves adding a new AARCH64_MOD_MUL_VL modifier, which is
why I split it out from the other addressing modes.
For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, .... The patch
therefore extends value_aligned_p to handle non-power-of-2 alignments.

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

Modify AArch64 Assembly and disassembly functions to be able to fail and report why.
This patch if the first patch in a series to add the ability to add constraints
to system registers that an instruction must adhere to in order for the register
to be usable with that instruction.
These constraints can also be used to disambiguate between registers with the
same encoding during disassembly.
This patch adds a new flags entry in the sysreg structures and ensures it is
filled in and read out during assembly/disassembly. It also adds the ability for
the assemble and disassemble functions to be able to gracefully fail and re-use
the existing error reporting infrastructure.
The return type of these functions are changed to a boolean to denote success or
failure and the error structure is passed around to them. This requires
aarch64-gen changes so a lot of the changes here are just mechanical.

[PATCH, BINUTILS, AARCH64, 7/9] Add BTI instruction
This patch is part of the patch series to add support for ARMv8.5-A
extensions.
(https://developer.arm.com/products/architecture/cpu-architecture/a-profile/docs/ddi0596/a/a64-base-instructions-alphabetic-order/bti-branch-target-identification)
The Branch Target Identification instructions (BTI) are allocated to
existing HINT space, using HINT numbers 32, 34, 36, 38, such that
bits[7:6] of the instruction identify the compatibility of the BTI
instruction to different branches.
BTI {<targets>}
where <targets> one of the following, specifying which type of
indirection is allowed:
j : Can be a target of any BR Xn isntruction.
c : Can be a target of any BLR Xn and BR {X16|X17}.
jc: Can be a target of any free branch.
A BTI instruction without any <targets> is the strictest of all and
can not be a target of nay free branch.

AArch64: Update encodings for stg, st2g, stzg and st2zg.
This patch is part of a series of patches to introduce a few changes to the
Armv8.5-A Memory Tagging Extension. This patch updates the st*g instructions
to use a previously reserved field for a new register operand. Thus the
new versions of the instructions are as follows:
- STG Xt, [<Xn|SP>, #<simm>]
- STG Xt, [<Xn|SP>, #<simm>]!
- STG Xt, [<Xn|SP>], #<simm>
- STZG Xt, [<Xn|SP>, #<simm>]
- STZG Xt, [<Xn|SP>, #<simm>]!
- STZG Xt, [<Xn|SP>], #<simm>
- ST2G Xt, [<Xn|SP>, #<simm>]
- ST2G Xt, [<Xn|SP>, #<simm>]!
- ST2G Xt, [<Xn|SP>], #<simm>
- STZ2G Xt, [<Xn|SP>, #<simm>]
- STZ2G Xt, [<Xn|SP>, #<simm>]!
- STZ2G Xt, [<Xn|SP>], #<simm>
Committed on behalf of Sudakshina Das.

of an rs_align_code fragment.
|
|
|

|

|
Here we fill the frag with the appropriate info for padding the
|
|
|
|
|
output stream. The resulting frag will consist of a fixed (fr_fix)
|
|
|
|
|
and of a repeating (fr_var) part.
|
|
|
|
|
|
|
|
|
|
The fixed content is always emitted before the repeating content and
|
|
|
|
|
these two parts are used as follows in constructing the output:
|
|
|
|
|
- the fixed part will be used to align to a valid instruction word
|
|
|
|
|
boundary, in case that we start at a misaligned address; as no
|
|
|
|
|
executable instruction can live at the misaligned location, we
|
|
|
|
|
simply fill with zeros;
|
|
|
|
|
- the variable part will be used to cover the remaining padding and
|
|
|
|
|
we fill using the AArch64 NOP instruction.
|
|
|
|
|
|
|
|
|
|
Note that the size of a RS_ALIGN_CODE fragment is always 7 to provide
|
|
|
|
|
enough storage space for up to 3 bytes for padding the back to a valid
|
|
|
|
|
instruction alignment and exactly 4 bytes to store the NOP pattern. */

bfd_section_* macros
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

[BINUTILS, AARCH64, 4/8] Add Tag setting instructions in Memory Tagging Extension
This patch is part of the patch series to add support for ARMv8.5-A
Memory Tagging Extensions which is an optional extension to
ARMv8.5-A and is enabled using the +memtag command line option.
This patch add support to the Tag setting instructions from
MTE which consists of the following instructions:
- STG [<Xn|SP>, #<simm>]
- STG [<Xn|SP>, #<simm>]!
- STG [<Xn|SP>], #<simm>
- STZG [<Xn|SP>, #<simm>]
- STZG [<Xn|SP>, #<simm>]!
- STZG [<Xn|SP>], #<simm>
- ST2G [<Xn|SP>, #<simm>]
- ST2G [<Xn|SP>, #<simm>]!
- ST2G [<Xn|SP>], #<simm>
- STZ2G [<Xn|SP>, #<simm>]
- STZ2G [<Xn|SP>, #<simm>]!
- STZ2G [<Xn|SP>], #<simm>
- STGP <Xt>, <Xt2>, [<Xn|SP>, #<imm>]
- STGP <Xt>, <Xt2>, [<Xn|SP>, #<imm>]!
- STGP <Xt>, <Xt2>, [<Xn|SP>], #<imm>
where
<Xn|SP> : Is the 64-bit GPR or Stack pointer.
<simm> : Is the optional signed immediate offset, a multiple of 16
in the range -4096 to 4080, defaulting to 0.

+sha2: Enables the SHA1 and SHA2 instructions of Armv8-a,
enabled by default with +crypto.
These options have been turned on by default when +crypto
is used, as such no breakage is expected.
The reason for the split is because with the introduction of Armv8.4-a
the implementation of AES has explicitly been made independent of the
implementation of the other crypto extensions. Backporting the split does
not break any of the previous requirements and so is safe to do.

Split the AArch64 Crypto instructions for AES and SHA1+2 into their own options (+aes and +sha2).
The new options are:
+aes: Enables the AES instructions of Armv8-a,
enabled by default with +crypto.
+sha2: Enables the SHA1 and SHA2 instructions of Armv8-a,
enabled by default with +crypto.
These options have been turned on by default when +crypto
is used, as such no breakage is expected.
The reason for the split is because with the introduction of Armv8.4-a

[binutils][aarch64] SVE2 feature extension flags.
Include all feature flag macros.
The "sve2" extension that enables the core sve2 instructions.
This also enables the sve extension, since sve is a requirement of sve2.
Extra optional sve2 features are the bitperm, sm4, aes, and sha3 extensions.
These are all given extra feature flags, "bitperm", "sve2-sm4",
"sve2-aes", and "sve2-sha3" respectively.
The sm4, aes, and sha3 extensions are explicitly marked as sve2
extensions to distinguish them from the corresponding NEON extensions.
Rather than continue extending the current feature flag numbers, I used
some bits that have been skipped.

[binutils][aarch64] SVE2 feature extension flags.
Include all feature flag macros.
The "sve2" extension that enables the core sve2 instructions.
This also enables the sve extension, since sve is a requirement of sve2.
Extra optional sve2 features are the bitperm, sm4, aes, and sha3 extensions.
These are all given extra feature flags, "bitperm", "sve2-sm4",
"sve2-aes", and "sve2-sha3" respectively.
The sm4, aes, and sha3 extensions are explicitly marked as sve2
extensions to distinguish them from the corresponding NEON extensions.
Rather than continue extending the current feature flag numbers, I used
some bits that have been skipped.
gas/ChangeLog:
